Version 3.4 ASTER Level 2 Order Processing

This Terra ASTER surface reflectance Level 2 natural color composite image shows differences in reflectance over forested hills, irrigated agriculture, and arid regions. A new algorithm for generating ASTER Level 2 products has been released and includes updated input data source options.

Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER)

ASTER is one of five instruments aboard NASA’s Terra Earth observing satellite. A joint United States/Japan Science Team is responsible for instrument design, calibration, and data validation. ASTER data are used to create detailed maps of land surface temperature, reflectance, and elevation.


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.
