Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER)

ASTER provides high resolution visible (15m), near infrared (30m) and thermal infrared (90m) data on request. ASTER is onboard Terra and has a swath width of about 60km. ASTER is being used to obtain detailed maps of land surface temperature, reflectance and elevation. An order for ASTER data has been placed by an ASTER science team member to obtain data for mid January to end of February 2010. ASTER data can be downloaded from NASA.
