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 coverage for the Murrumbidgee Catchment is summarised below. ASTER data can be downloaded from NASA.

ASTER overpass time

The ASTER overpass times for the SMAPEx study area have been determined from a Fortran program based on the NORAD data, and are provided in the table below. Date and time are in UTC.

                  ●=full ASTER coverage of airborne box;        ○=partial ASTER coverage

                  ●=concurrent;                                                                ●=non concurrent

No coverage were found during 5th to 10th July 2010.
