Istvan Laszlo's research interests include atmospheric radiation,
radiative transfer, radiation budget and remote sensing of atmospheric
and surface properties from space. He is a co-author of the well-known
Discrete Ordinate Radiative Transfer (DISORT) code, worked on estimating
the broadband top of atmosphere albedo from narrowband sensors;
developed an algorithm for estimating the shortwave radiation budget,
surface albedo, aerosol and cloud optical depth from satellite data. He
is currently working on remote sensing of aerosol properties from space
and on the estimation of the shortwave radiation budget from operational
geostationary satellites.
Istvan Laszlo was an elected member of the International Radiation
Commission of the International Association of Meteorology and
Atmospheric Physics (IAMAP) and a member of the Scanner for Radiation
Budget (ScaRaB) International Science Team. His current memberships
include the Clouds and the Earth’s Radiant Energy System (CERES) and
NPOESS Science Teams, and the Operational Algorithm Teams for the NPOESS
Aerosol Polarimeter Sensor (APS) and for the NPOESS Earth Radiation
Budget (ERBS) instrument. He is also a co-chair of the Earth Radiation
Budget Oversight Panel (EPOP) and the chair of the GOES-R Radiation
Budget Algorithm Working Group at NESDIS.
Istvan Laszlo is the aerosol and radiation budget lead scientist at
NESDIS/STAR. He also served as the Acting Chief of the Environmental
Monitoring Branch between Sep, 2007 and Aug, 2008.
