Rajendra Bhatt (Contractor)

Title: Senior Scientist
Technical Focus Area: Climate Science, Photonics
Mission Project: CERES
Study Topic: Sensor calibration


Rajendra Bhatt is a Senior Research Scientist with Science Systems and Applications, Inc. (SSAI), Hampton, VA, supporting on-going radiometric calibration projects at the Climate Science Branch of the NASA LaRC Science Directorate. He has 14 years of experience in developing techniques for in-flight calibration of geostationary and low earth-orbiting satellite imagers to assess their radiometric performance on orbit and ensure the usability of the satellite observations for climate studies. He is an expert in characterizing and modeling the bidirectional reflectances over invariant Earth targets, including deserts, polar ice caps, and tropical deep convective clouds. He has utilized these models to establish radiometric harmonization among the MODIS, VIIRS, AVHRR, and numerous geostationary sensors to facilitate consistent satellite retrieval datasets. Furthermore, he has studied the differences between multiple reference solar irradiance spectra, and quantified their impact on satellite sensor inter-calibration. For the CERES project, he also independently monitors and validates the temporal radiometric stability and calibration consistency of the MODIS and VIIRS reflective solar channels in the L1B products. He has a strong foundation in photonics and electrical engineering, along with hands-on experience with designing and characterizing spectrally selective surfaces for thermal emission control, analog and digital hardware designing, prototyping, testing, and debugging. He has published more than 30 scientific articles in peer-reviewed journals.
