High Resolution Directional Polarimetric Camera (DPC) used in theremote sensing of aerosol properties

摘要

A new airborne Directional Polarimetric Camera (DPC) was developed to retrieve aerosol optical and microphysical properties over urban with high spatial resolution, dealing with the apportionment of sources and controls on air quality in the city. The instrument is a Polarization and Directionality of Earth's Reflectance (POLDER) type polarized camera with significant improvement in the space resolution realizing monitoring aerosol emission and absorption sources like megacities in China. This paper describes the DPC instrument characteristics, instrument calibration, and the flight experiment in the Delta Peal Region of China.
