Title Verification of Aerosol Optical Depth Retrieval Using the Terra Satellite.
Publication Date Jun 2012
Media Count 55p
Personal Author B. D. Cimbora
Abstract A method for sensing retrieval of Aerosol Optical Depth (AOD) was investigated by Vincent (2006). This technique is known as the Shadow Method. Using high-resolution commercial satellite imagery, Vincent was able to calculate AOD values by measuring the radiance of a scene in and out of a shadow. Over the last five years, several advancements have been made to validate the Shadow Method. Using the MODerate resolution Imaging Spectrometer (MODIS), scenes were analyzed over desert regions to exploit shadows generated by clouds and terrain. The results were quickly compiled using MATLAB. Results confirm that the Shadow Method is capable of producing AOD values.
