Enhancing the Quality of Typhoon Image Database Using NOAA AVHRR Data Received in Thailand

The Japanese geostationary meteorological satellite GMS-5, or also known as ”Himawari,” is positioned at 140◦E above the equator, and serves as a powerful tool for monitoring typhoons on the Pacific Ocean. This satellite is best suited for the monitoring of typhoons because of frequent observation, wide coverage, and fixed scan range. However, the degradation of effective resolution due to earth curvature arises as a limitation to the monitoring of typhoons in South East Asia. To improve the quality of typhoon imagery over those areas, here we propose to solve this problem by means of combining GMS satellite data with NOAA polar orbiting satellite data, in particular those received at Asian Institute of Technology (AIT), Thailand. We compare the characteristics of satellite imagery from those two satellites with an example, and demonstrates ideas on the comprehensive collection of typhoon imagery.
