The AERONET program is a federation of ground-based remote sensing aerosol networks established by NASA and PHOTONS (Univ. of Lille 1, CNES, and CNRS-INSU) and is greatly expanded by collaborators from national agencies, institutes, universities, individual scientists, and partners. The program provides a long-term, continuous and readily accessible public domain database of aerosol optical, microphysical and radiative properties for aerosol research and characterization, validation of satellite retrievals, and synergism with other databases. The network imposes standardization of instruments, calibration, processing and distribution.
Bucharest CIMEL sunphotometer is part of AERONET since Jul. 2007 (P.I. Dr. Doina Nicolae; site manager Dr. Anca Nemuc), providing continuous data (automatic data collection and transfer).
