Abstract

The Moderate Resolution Imaging Spectroradiometer (MODIS) and Multiangle Imaging Spectroradiometer (MISR) are instruments onboard the satellite Terra which provide aerosol optical depth (AOD) measurements over a wide spatial coverage. The Aerosol Robotic Network (AERONET) is a network of ground-based sun photometers which measure AOD several times a day. In this paper, satellite retrievals of AOD for January 2009 to May 2010 were validated through the AERONET site at the Manila Observatory. Correlation of MODIS and AERONET yielded an R² = 0.77 while MISR and AERONET had an R² = 0.88. Excluded data sets were attributed to cloud contamination. Improvements in the cloud-screening algorithms of the satellite retrievals are recommended.
