Istvan Laszlo
Satellite Meteorology and Climatology Division
Environmental Monitoring Branch
Research Scientist / Acting Branch Chief
Istvan Laszlo received an M.S. degree in
Astronomy/Physics and a Ph.D. degree in Physics (Meteorology)
from the Eötvös Loránd University
in Budapest, Hungary. He worked at the Institute for Atmospheric
Physics of the Hungarian Meteorological Service before joining
the faculty of the Department
of Atmospheric and Oceanic Science at the University of Maryland
at College Park, Maryland. Since April 2001 he has been with the
National Oceanic and Atmospheric Administration.
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) at NESDIS.
Istvan Laszlo has published over 30 peer-reviewed scientific
articles and conference proceedings, one book chapter, five monographs, and presented over 40 scientific papers at professional meetings.
