photo of Ivan CsiszarIvan Csiszar received his Ph.D. in Earth Sciences in 1996 from the Eötvös Loránd University in Budapest, Hungary. From 1988 until 1997 he worked at the Hungarian Meteorological Service, during which time he also visited the Max-Planck-Institut für Météorologie in Hamburg, Germany, and the Laboratoire de Météorologie Dynamique in Palaiseau, France. He was a visiting scientist at NOAA/NESDIS between 1997 and 2001 and an Associate Research Scientist at the Department of Geography of the University of Maryland between 2002 and 2008. He joined NOAA/NESDIS/STAR in 2008.

Ivan Csiszar's early research focused on atmospheric sounding and on the retrieval of cloud optical and microphysical properties. He also worked on various issues related to the retrieval of land surface properties. He led several NOAA and NASA-funded research projects aimed at fire mapping and evaluating fire products and impacts, including products from the Advanced Very High Resolution Radiometer (AVHRR), the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Visible Infrared Imaging Radiometer Suite (VIIRS).

Currently he is the NOAA Joint Polar Satellite System (JPSS) Product Lead for the operational VIIRS Active Fire product and the Lead of the NOAA JPSS Land Product Domain. He is also involved in activities aimed at operational applications of fire products in disaster and resource management through the NOAA JPSS Fire and Smoke Proving Ground Initiative. He is also working on the use of satellite-derived land products in Numerical Weather Forecast models, in collaboration with the Land Team at the Environmental Modeling Center (EMC) of the National Centers for Environmental Prediction (NCEP).

Dr. Csiszar has been an active contributor to the Fire Mapping and Monitoring thematic area of the Global Observation of Forest and Land Cover Dynamics (GOFC-GOLD) program and Group on Earth Observations (GEO). He has led the evaluation and specification process of the Fire Disturbance Essential Climate Variable for the Global Climate Observing System (GCOS) and the Global Terrestrial Observing System (GTOS). He has also served as the Associate Editor of the International Journal of Wildland Fire.

Ivan Csiszar has published over 50 peer-reviewed journal articles and book chapters and has given numerous invited and contributing presentations at scientific conferences. He has taught full courses on dynamic meteorology and climatology, and has been a lecturer on weather, climate and satellite-based environmental monitoring for courses at domestic and international institutions. He has organized and chaired international scientific workshops and conference sessions related to fire monitoring. He has also served on scientific advisory and review panels for NOAA and NASA.

He is the recipient of the Zeldovich Award from the Scientific Commission A of the Committee on Space Research, the World Meteorological Organization Research Award for Young Scientists, and awards from the Hungarian Academy of Sciences and the Hungarian Meteorological Society. In 2014 he was part of the NOAA JPSS Environmental Data Record (EDR) Team to receive the United States Department of Commerce Bronze Medal Award for his work on the operational data products from the Suomi National Polar-orbiting Partnership (NPP) satellite. In 2023 he was part of the joint NOAA Oceanic and Atmospheric Research (OAR) and NESDIS Team to receive the United States Department of Commerce Silver Medal Award for the development of the High Resolution Rapid Refresh (HRRR)-smoke and its operational value during the 2022 wildfire season.
