Brief Bio

Dr. Isaac Moradi is a remote sensing scientist with over fifteen years of experience specializing in radiative transfer modeling; Observing System Simulation Experiments (OSSE); data assimilation; satellite data analysis and bias correction; atmospheric humidity and ice clouds; inverse methods and retrieving geophysical variables from satellite observations; solar radiation resource assessment; quality assurance of solar radiation and in-situ radiosonde measurements; and developing new instrument concepts especially for measuring tropospheric humidity.

Isaac worked at the Renewable Energy Organization of Iran from 2005 to 2007 where he led the development of Iranian solar radiation atlas from geostationary satellite observations and installation of radiometric networks for the validation of solar radiation retrievals. Additionally, Dr. Moradi contributed to developing control systems for parabolic trough solar thermal power-plants. Isaac then joined the University of Tehran (UT) as an Assistant Professor in 2007. While at UT, in addition to teaching courses in Probability and Statistics and Microclimatology, Dr. Moradi conducted research on thermal remote sensing and radiative transfer modeling. Isaac moved to the Department of Computer Science, Electrical and Space Engineering, Luleå University of Technology (LTU, Sweden) in 2008. While at LTU, in addition to giving lectures on Atmospheric Physics, Isaac conducted research on microwave remote sensing, radiative transfer modeling, and validation of in-situ radiosonde measurements.

Dr. Moradi joined UMD/ESSIC in 2010 where he led the development of homogenized climate data records from microwave humidity sounders in collaboration with the NOAA Center for Satellite Applications and Research (STAR). In addition, Dr. Moradi served as the Principal Investigator of several projects on calibration and validation of microwave satellite measurements. Meanwhile, Isaac worked at the NOAA Joint Center for Satellite Data Assimilation where he led the development of the Community Global Observing System Simulation Experiment Package (CGOP). CGOP is currently used by several NOAA divisions for generating satellite radiances, GPS-RO, and in-situ measurements for conducting OSSE experiments. Dr. Moradi joined the NASA GMAO in 2016 where his research is focused on radiative transfer modeling, OSSE, all-sky radiance data assimilation, and severe weather prediction.
