Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER)

Source: http://terra.nasa.gov, access on 28th, Apr. 2010

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

ASTER overpass time

ASTER coverage for the Murrumbidgee Catchment during the AACES-2 campaign has been calculated by a Fortran program based on NORAD data for 29th, Aug. 2010, and is summarized in the table below. Date and time are in UTC. Aircraft flights were assumed to be conducted at 7:45 for descending overpass and 20:35 for ascending overpass.

  : Transect flight within 6 hours   : Patch flight within 6 hours
: Fully covered : Partially covered
