Research Interests:

The primary goal of the SO2 group at UMBC and GSFC is generation of UV volcanic eruption data products (SO2 and ash) from NASA Total Ozone Mapping Spectrometer (TOMS) missions and from hyperspectral Ozone Monitoring Instrument (OMI) on NASA EOS Aura satellite to allow SO2 detection from satellites for both volcanic and anthropogenic sources, which is an important component of aviation hazard alerts and air quality monitoring from space.

Biography:

Dr. Nickolay A. Krotkov received a Ph.D. in oceanography (physics and mathematics1990) from the P. P. Shirshov Institute of Oceanology Russian Academy of Sciences, and a MS (with honor) in Remote Sensing (1985) and a BS in physics (1983) from Moscow Institute of Physics and Technology, Russia. His Ph.D. thesis is on using polarization properties of scattered solar radiation in the oceanic remote sensing. He worked for 2 years at Russian Central Aerological Observatory on surface UV radiation modeling. Since 1993 he worked as a Post Doctoral Research Associate at USRA and UMCP and as research scientist at Raytheon on NASA Total Ozone Mapping Spectrometer mission to study volcanic clouds, surface and underwater ultraviolet radiation and aerosols. In 2000 he joined the Goddard Earth Sciences and Technology Center at the University of Maryland, Baltimore County, as a senior research scientist. His main research interests include radiative transfer modeling, ground-based and satellite UV remotes sensing of trace gases and aerosols. Since 2006 he is member of the Aura OMI science team responsible for SO2 data. He has published over 40 refereed papers where the most recent ones are concentrated on satellite estimation of the surface ultraviolet irradiance, SO2 and measuring of aerosol UV absorption properties.
