The ASTER instrument
consists of three sub-instruments:
VNIR (Visible and Near
Infrared): The VNIR instrument measures 3 spectral bands that fall within the visible
and near infrared wavelengths. It has a 15 m resolution.
SWIR (Shortwave
Infrared): The SWIR instrument measures 6 spectral bands in the near infrared
wavelengths. It has a 30 m resolution.
TIR (Thermal Infrared):
The TIR instrument measures 5 spectral bands in the thermal infrared
wavelengths. It has a 90 m resolution.

information about the instrument click here. For characteristics about the instrument
such as the spectral ranges of the bands and the data rate click here.
ASTER data is
acquired based on submitted requests to observe specific areas. Below are links
to the different ways in which ASTER data can be acquired.
