Abstract
Using the NOAA-HRPT data received at the Tohoku University, a satellite image database for regional researches is produced at the Computer Center of the university. The database is called“Tohoku Image Database: TIDAS”. The TIDAS is open for public, and can be accessed through computer networks. The albedo and brightness temperature processed from the AVHRR channel 2 and channel 4 are geocoded, and sent to the Computer Center for TIDAS production every day. The TIDAS contains the satellite images in 99.2% of the days from April, 1990 to the present. This paper describes the overall features of the TIDAStogether with the related background.
