Abstract

Aerosol optical depth (AOD) measures the extinction of light due to aerosols in the atmosphere. The Moderate Resolution Imaging Spectroradiometer (MODIS) provides AOD measurements twice a day over a wide spatial area through satellite remote sensing. The Aerosol Robotic Network (AERONET) is a network of ground-based sun photometers which measure AOD several times a day. In this paper, MODIS measurements are validated through the AERONET site at the Manila Observatory for February-June 2009. Using a validation method which minimizes the error between the MODIS and AERONET mean, an R² of 0.9789 was obtained.
