Above-Cloud Aerosol Properties from Multi-Spectral Satellite and Aircraft Measurements during the ORACLES Field Campaign

Aircraft measurements of aerosol and cloud optical properties during the ObseRvations of Aerosols above CLouds and their intEractionS (ORACLES) field campaign during 2016 and 2017 has offered a validation source and algorithm development for satellite measurements. Specifically, the retrieval of aerosol and cloud optical properties from the Spinning Enhanced Visible and Infrared Imager (SEVIRI) and polar-orbiting sensors are compared with the Spectrometers for Sky-Scanning, Sun-Tracking Atmospheric Research (4STAR) data set. An estimation of the temporal variations of the aerosols and clouds are evaluated. Biases in the retrieval of optical properties associated with spatial resolution among various sensors are examined. This study also compares the differences in aerosol direct radiative effects when computing from aircraft and satellite measurements.
