Measurements of UVB started in India around 1980 by independent scientists around India. Since its inception, the care of these instruments has changed hands several times and future funding is in jeopardy. The instruments were banded into a more formal network under the Indian Middle Atmospheric Programme (IMAP) in 1982-83. The IMAP program ended in 1989 and funding has continued for all stations except Jodhpur since then under ISRO-UGC. The six instruments originally included Jodhpur, Pune, Visakhapatnam, Mysore, New Delhi and Trivandrum. The instruments are filter based instruments which measure four wavelength bands with 10 nm FWHM. The center wavelengths are roughly 280, 290, 300 and 310 nm. For the moment, Dr. S. C. Chakravarty of the Space Science Office, ISRO and B. H. Subbaraya are keeping the program running.

Instruments:

All instruments are four channel (280 nm, 290 nm, 300 nm and 310 nm +-10) filter instruments. The Pune instrument may be slightly different because it was built separately.
