Abstract

The High Resolution Picture Transmission (HRPT) and Automatic Picture Transmission (APT) data from the National Oceanic and Atmospheric Administration weather satellite Advanced Very High Resolution Radiometers were the primary sources of satellite data used in this study. Several models were developed to convert the gray-level digital numbers of the satellite imagery into temperature values. The satellite-derived temperatures, which were stored in a geographic information system database, were well correlated with ground-truth temperature measurements. The results of this study indicated that the APT data is useful for lake temperature estimation as compared with the HRPT data. In other words, both HRPT and APT data are capable of being converted into lake surface temperature with acceptable accuracy.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
