Professional Objectives: Advance the knowledge of clouds, aerosols, ecosystem structure and function, albedo, and feedbacks to climate. Build a well-calibrated, atmospherically corrected and feature-rich airborne dataset for calibration and validation of satellite sensors. Conduct elaborate experiments and develop new methods to define important surface and atmosphere radiative transfer functions, and improve remote sensing retrievals of aerosols and clouds using laboratory, ground-based, airborne and satellite remote sensing. Develop instruments and technologies for new measurements in support of Earth science missions. Inspire future scientists through education and outreach.
