ASTER V002 and V003 Products from the LP DAAC
The Japanese Ground Data System (GDS) started processing ASTER Level-1 data (and re-processing of earlier data) using a newer, improved algorithm (Version 04.00R00) and also an improved set of radiometric calibration and geometric correction coefficients databases on May 1, 2001. To avoid user confusion in identifying different versions of the same granule in search results, it was decided to migrate Level-1 data produced in Japan on and after May 1, 2001 (and the routinely-produced higher-level products derived from them) to a separate collection, which is version 003.
The key determinants of the collection split are:
- Production Date & Time: May 1, 2001 at GDS, Japan
- PGE Version: Version 04.00R00 (and higher versions) at GDS, Japan
- Geometric Database Version: 02.00 (and higher versions)
- Radiometric Database Version: 02.05 (and higher versions)
Therefore, there are 2 separate collections (Versions 002 and 003) of ASTER Level-1 and Level-3 data sets available from the LP DAAC archives:
| Long Name
