The application of airborne shortwave spectral irradiance measurements to atmosphere and surface remote sensing.

다국어 초록 (Multilingual Abstract)

We apply airborne shortwave spectral irradiance measurements to atmosphere and surface remote sensing. Spectral surface albedo and cloud optical properties (optical depth and effective radius) are retrieved by indirectly relating measurements of reflected sunlight from Earth's surface and from clouds to these parameters. The inversion techniques and the radiative transfer model used to simulate the measured upwelling and downwelling irradiance needed in the inversions are discussed. Results are shown from measurements taken during two field campaigns: The Megacity Initiative: Local and Global Research Observations (MILAGRO) and the Intercontinental Chemical Transport Experiment (INTEX-A). The airborne-based retrievals are compared to satellite-retrieved quantities. Also discussed is a theoretical method for evaluating the contribution of uncertainty and error in measured and modeled irradiance to the accuracy and uniqueness of the retrieved cloud properties.
