Utilizing aerosol data from satellite measurements has an advantage of identifying pollution episodes on places where there are minimal to no data measurements. Such applications are available from a constellation of satellite sensors polar-orbiting the earth on a regular basis, called the A-train. This study uses the vertical feature mask from one of the satellite-constellation, the Cloud-Aerosol LiDAR and Infrared Pathfinder Satellite Observations (CALIPSO) to determine the vertically-resloved aerosol quality over the Philippines. On the ground, data from the Aerosol Robotics Network (AERONET) station in the Manila Observatory was used to quantitate the Aerosol optical depth (AOD). From a selected time frame of satellite data for the whole month of November 2011 it was observed that the AOD on the ground level reached as high as 3.3 on the afternoon of November 2, 2011. Severe cases of pollution from East Asia, specifically from China were also evident on the study period. Satellite data retrievals has shown its applicability for aerosol studies in the Philippines as of the moment when we do not have the technologies for in depth comparison of aerosol levels with the neighboring Asian countries.
