UNITED STATES

UV monitoring efforts in the U.S. are being coordinated through the US Global Change Research Program. In addition to the networks described below, there are a variety of UV monitoring instruments operated independently at universities, hospitals and research institutes. Others are operated by interested individuals.

The National Science Foundation (NSF)

Biospherical Instruments Inc. (BSI), under the direction of National Science Foundation, is responsible for the operation and maintenance of the NSF UV Monitoring Network, and for the distribution of network data to the scientific community. The network, established in 1988, has since been in operation responding to predictions of increased UV radiation in the polar regions. The network currently consists of six high resolution spectroradiometers (BSI model SUV-100). Three instruments are in Antarctica, the other three are located in southern-most Argentina, the northern-most point in Alaska, and in San Diego, California. The San Diego system also serves for training and testing. Multi-channel filter radiometers (BSI models GUV-511C and GUV-541) were added to all sites in 2003. The network performs measurements of global spectral irradiance in the UV and visible. Data is provided to researchers studying the effects of ozone depletion on terrestrial and marine biological systems. Network data is also used for atmospheric research, and the validation of satellite observations.

The Environmental Protection Agency (EPA)

The U.S. Environmental Protection Agency (EPA) developed a program to operate a monitoring network to measure ultraviolet (UV) radiation flux at the earth's surface using the Brewer Spectrophotometer instrument. Although this network ceased operation in 2006, data and other information is available by following the link below. The EPA's monitoring program included 21 Brewer spectrophotometers located in both urban (polluted) and National Park locations. These enabled the EPA to improve the algorithms on which the index predictions are based. Other parameters measured included total column ozone, cloud cover,and interfering tropospheric pollutants. Various other experiments were performed to determine other factors, such as cloud type and aerosols, that may affect the UV flux. Network operations and instrument calibration was undertaken by the National UV Monitoring Center (University of Georgia) and independent calibration audits were performed by the Central UV Calibration Facility. The EPA currently provides for public awareness of exposure to UV radiation through the adaptation and publication of a predictive UV "exposure Index." This "Index," which is in agreement with the standards set by WHO and WMO for providing UV index information, was developed in conjunction with the National Weather Service, and was initiated on June 29, 1994 in 58 cities across the US.

The United States Department of Agriculture (USDA)

The USDA began operating a network of broadband meters in 1992. Since that time, the network has expanded to 37 sites and has introduced additional instrumentation throughout the network. Each station has a UV-B broadband meter and PAR quantum sensor, plus visible and UV 7-channel multi filter rotating shadowband radiometers (MFRSR's). Most stations also employ air temperature and humidity sensors, a Licor, barometers, and UV-A sensors. The data are displayed on the world wide web daily and include direct, normal, diffuse, and total horizontal irradiance at 13 nominal wavelengths (300,305,311,317,325,332,368,415,500,610,665,862,940 nanometers). The network is expected to expand to approximately 40 sites.

The US Department of Commerce/NOAA UV Monitoring Network

Three NOAA monitoring networks have been collecting UV data.

Monitoring Locations & Instrumentation

ISIS

NOAA's Surface Radiation Research Branch (SRRB), part of the Earth System Research Lab's (ESRL) Global Monitoring Division (GMD), operates the Integrated Surface Irradiance Study (ISIS) Network. This network monitors surface radiation in the continental US, in collaboration with NOAA's Surface Radiation Budget Measurement (SURFRAD) Network. ISIS operates at two levels: level 1 monitors incoming radiation only and level 2 (SURFRAD) focuses on the surface radiation budget. NOAA's Air Resources Laboratory in Oak Ridge operates the level 1 ISIS sites.

SURFRAD

NOAA's Surface Radiation Research Branch also operates and maintains seven sites in the United States forming the SURFRAD network for the purpose of understanding the radiation energy balance. The sites are equipped with the following instrumentation:
A Yankee multi-filter rotating shadowband radiometer (MFRSR) measuring aerosols, a LI-COR sensor measuring photsynthetically active radiation (PAR), A Yankee UVB-1 broadband radiometer measuring incoming UV-B radiation, an Eppley PSP broadband radiometer measuring total incoming solar radiation, an Eppley Normal Incidence Pyrheliometer (NIP) measuring direct solar radiation, tow Eppley Precision Infrared Radiometer (PIR) measuring incoming and outgoing long-wave radiation, an Eppley 8-48 Pyranometer measuring diffuse radiation, A Yankee Total Sky Imager (TSI) measuring cloud cover, and a Spectrosun SR-75 pyranometer measuring reflected solar radiation. In addition, all sites maintain air temperature, relative humidity, and pressure sensors, as well as wind speed and direction gauges.

STAR

NOAA's Global Monitoring Division (GMD) also operates and maintains five baseline observatories around the world which, in conjunction with other network instrumentation, forms the Solar and Thermal Atmospheric Radiation (STAR) Network. The STAR group's activities involve empirical and theoretical research of the Earth's surface radiation budget. The group specializes in the investigation of climatically significant variations in long-term radiation and meteorological measurements made primarily at a globally diverse network of surface sites. Research interests are in the extent and cause of observed variations, and in collaborating with other research groups making satellite observations and climate model calculations. In addition, the group makes some relative observations of spectral solar radiation for the purpose of remote sensing of certain atmospheric constituents. A relatively new program in the group is the absolute measurement of spectral solar UV for the investigation of the interaction of ozone and solar radiation.
In addition to the five GMD baseline stations, the STAR network maintains three additional sites which are components of the World Climate Research Program's Baseline Surface Radiation Network (BSRN). Five more sites in addition to all of the GMD baseline sites form part of the WMO's Global Atmospheric Watch (GAW) program. Three NSF sites in conjunction with Biospherical Instruments also contribute to the STAR network.

The Smithsonian Institute

The Smithsonian Institute's Environmental Research Center (SERC) is a participant in the US Interagency Ultraviolet Radiation Monitoring Network, whose overall goals are to define short and long-term variation in spectral UV-B; study the variation of UV-B over latitudinal gradients; and study the effects of clouds and other factors, such as aerosols, on UV-B. The program also supports SERC's program of UV-B effects research, which is conducted by the SERC's Photobiology/Solar Research Laboratory. Currrently in operation are four monitoring sites, detailed below, along with locations operated jointly with other agencies such as NIST, and the USDA's Forest Products Laboratory (FPL). Employed at each SERC site is an SR-18, and in some cases, an SR-19 UV-B scanning radiometer which also monitors short wavelength UV-A. The instruments are designed, consructed, and calibrated at SERC to maintain quality control as needed to ensure consistent long term data.

The National Institute of Standards and Technology (NIST)

The US Department of Commerce's National Institute of Standards and Technology (NIST) maintains a solar UV-B network. It is operated jointly by the Materials and Construction Research Division, the Building and Fire Research Laboratory, and the Smithsonian Environmental Research Center (SERC). Because UV radiation plays a role in the degradation of polymeric materials such as asphalt, paint, and plastics, the coatings service life community now has access to data specific to their needs. The sites within the network are all running the SERC SR-18 UV-B scanning radiometer.

The Department of Energy Atmospheric Radiation Measurement (ARM) Program

The US Department Energy's Atmospheric Radiation Measurement (ARM) Program maintains three main monitoring sites each with a host of extended facilities. In addition, ARm supports a mobile laboratory, and an unmanned aerospace vehicle (UAV) platform measuring solar radiation. A primary objective of the ARM program is improved scientific understanding of the fundamental physics related to interaction between clouds and radiative feedback processes in the atmosphere. ARM focuses on obtaining continuous field measurements and providing data products that promote the advancement of climate models.

The University of Oregon Solar Radiation Monitoring Laboratory (SRML)

The University of Oregon's SRML is a regional solar radiation data center, whose goal is to provide sound solar resource data for planning, design, deployment, and operation of solar electric facilities in the Pacific Northwest. Creating the long-term solar radiation data base necessary to achieve this goal requires persistence, maintenance of high standards, and an effort to educate people on the importance of a solar radiation database and how to use the database. The monitoring network consists of five reference stations and twelve subsidiary stations. During the period 2001-2003, we plan to add two more reference stations. These reference stations can supply the engineering data needed for large-scale system designs and for improved ground truthing of satellite solar radiation data, while the subsidiary stations provide solar resource information from a wider variety of locations, along with further data to validate satellite estimates.

The National Renewable Energy Laboratory's (NREL) Cooperative Network for Renewable Resource Measurement (CONFRRM)

The Cooperative Network for Renewable Resource Measurements (CONFRRM) is a cooperative effort between the Department of Energy's NREL and other agencies to conduct long-term solar radiation and wind measurements at selected locations in the United States. CONFRRM expands the geographic coverage of measurement locations and provides high quality data for determining site-specific resources, as well as data for the validation and testing of models to predict available resources based on meteorological or satellite data. The CONFRRM network complements and provides additional geographic coverage to the National Oceanic and Atmospheric Administration's (NOAA's) Integrated Surface Irradiance Study (ISIS) network. Solar data elements measured and reported by the CONFRRM sites include: global horizontal irradiance (total solar radiation) and diffuse horizontal irradiance (synonym for diffuse sky radiation) measured with a precision spectral pyranometer; direct normal irradiance (synonym for beam radiation) measured with a pyrheliometer; and global horizontal irradiance measured with a LI-COR pyranometer. Meteorological data include air temperature, relative humidity, pressure, and wind.

The World Climate Research Program's Baseline Surface Radiation Network (BSRN)

BSRN is a project of the World Climate Research Programme (WCRP) and the Global Energy and Water Experiment (GEWEX) and as such is aimed detecting important changes in the earth's radiation field at the earth's surface which may related to climate changes. The data are of primary importance in supporting the validation and confirmation of satellite and computer model estimates of these quantities. At a small number of stations (currently fewer than 40) in contrasting climatic zones, covering a latitude range from 80�N to 90�S, solar and atmospheric radiation is measured with instruments of the highest available accuracy and with high time resolution (1 to 3 minutes). The BSRN was recently (early 2004) designated as the global baseline network for surface radiation for the Global Climate Observing System (GCOS). The radiation data are stored together with collocated surface and upper-air meteorological observations and station `metadata' in an integrated database at ETH Zurich, which has been designated as the World Radiation Monitoring Center (WRMC).

NOAA/NIST Central UV Calibration Facility (CUCF)

The UV central calibration laboratory is operated by the Surface Radiation Research Branch (SRRB) of NOAA's Earth System Research Laboratory's Global Monitoring Division in Boulder, Colorado. It is responsible for transfering NIST absolute standards to operational UV monitoring instruments on a regular basis. The design and development of this facility has been a joint effort involving U.S. governmental agencies and university scientists. It offers calibration of broadband, filter and spectral instruments. Both laboratory and field calibrations are also performed. In addition, the facility hosts an annual intercomparison of North American UV monitoring instruments. A portable field calibration device has also been developed and the facility serves private industry and non-USA agencies by offering services to manufacturers of UV measuring devices.

UV monitoring and research in the US is carried on by several agencies with coordination through the US Global Change Research Program.

Daily UV Index for US cities in text format supplied by the National Weather Service, this site is updated daily

Daily UV Index for the US as a color map supplied by the National Weather Service, this site is updated daily

The Weather channel offers a map of the current UV Index as well as a variety of other information such as weather forecasts for the U.S. and select cities.

Accu-weather offers maps of the UV Index along with information such as weather forecasts for the U.S. and select cities.

NOAA's UV Index page offers daily maps of the UV index as well as maps of monthly mean levels and past levels.

The US Department of Agriculture operates 26 UV monitoring stations with a variety of instruments primarily broad-bands. The site which is updated daily supplies daily maps from each of their instruments.

The Atmospheric Radiation Measurements Program has in depth measurements of a number of radiation, meteorological and constituent parameters including UV broad-band meters at a number of sites and a UV Spectroradiometer (UVS) at the Southern Great Plains site only.

NOAA's SurfRad program monitors surface radiation including UV at six sites in the U.S. The data are available from this site which is updated daily.

The National Science Foundation has four spectral radiometers in Antarctica, one in Barrow, AK and one in San Diego, CA. Data and summaries are available from this site which is updated periodically.

The US EPA together with the National Park Service operates 21 Brewer UV monitoring meters including 15 in National Parks. Programmatic description, plots and data downloads are available from this site which is operated by the US EPA.

NOAA's ISIS program operates nine broad-band meters in the continental US. Data are available as well as the prior day's diurnal plots.
