Remote Sensing of Aerosol Optical Depth Using an Airborne Polarimeter over North China
Remote Sensing, 2017 The airborne Atmosphere Multi-angle Polarization Radiometer (AMPR) was employed to perform airborne measurements over North China between 2012 and 2016. Seven flights and synchronous ground-based observations were acquired.

Determination of aerosol content in the atmosphere from ERTS-1 data [PDF]
The author has identified the following significant results. Significant results, relating the radiance over water surfaces to the atmospheric aerosol content, have been obtained. The results indicate that the MSS channels 4, 5, and 6 centered at 0.55, 0.
