Satellite Data

The current processing stream for Day and Night Fog/Low Cloud detection and related parameters are obtained from Terra and Aqua MODIS radiances and retrievals from LAADS Web.

Presently, we are also testing retrievals and processing of fog-related parameters from geostationary satellites, for near-real time continuous monitoring of fog, water vapor and aerosols over south Asia.

Output images available from our web portal may be used by authors in presentations. When doing so, please include a reference to “Satellite Fog monitoring (Gautam et al.)”. Processed fog-related satellite data and original measurements/retrievals can be obtained by, contacting Ritesh Gautam at rgautam<at>iitb.ac.in.
