Abstract

The Ocean Color Imager (OCI) onboard the ROCSAT-1 Satellite was employed to demonstrate its capability in monitoring sandstorm events around Mongolia and northwestern China where they have been occurring in great frequency over these past few years. The OCI measures the radiance from the visible to near infrared regions in six spectral channels. The radiance can be used to calculate the aerosol optical depth (AOD) of the atmosphere through an atmospheric correction algorithm. The variation in the AOD during January and February of 2001 is investigated in this study. A set of OCI images covering the Yellow Sea was selected for analysis. The results showed that the AOD values increased significantly after the sand-storms erupted, where its value was almost four times higher than before.
