Agarwal, an eminent environmental scientist and former professor of IIT K and also former Member Secretary of CPCB during 1980- 83. Its sole mission is to protect and improve the air quality in India. Besides producing indigenous technology and instruments, it has carried out many assignments of EIA and industrial monitoring and has acquired competence and experience in monitoring air environment.
