Vladimir Kondratovich earned his Ph.D. degree from the University of St. Petersburg, Russia in the area of theoretical spectroscopy. His work on absorption spectra in strong fields allowed for better understanding of the distant space observations. For the last two decades, he has worked on the calibration and data processing of the spectrometer sensors flown on the geostationary, low-Earth, and high-Earth orbits by the GOES-R, METEOSAT, SNPP, JPSS, and THEMIS missions. The current focus of his research is on the geometric calibration of images produced by the ABI sensor onboard the GOES-16 and GOES-17 satellites. This work is part of the scope of the Calibration Work Group (CWG) at NOAA/NESDIS/STAR. He is the recipient of the Significant Achievements Award by the GOES-R Flight Program and several other awards. Dr. Kondratovich supports international collaboration with EUMETSAT, ESA, KMA, and JMA, presents results at the international and national conferences, and reviews submissions to several international journals.
