Welcome to the Data Pool at the Land Processes Distributed Active Archive Center (LP DAAC). The Data Pool is an online archive that provides, without a charge, FTP access to selected LP DAAC data products from both the Terra and Aqua satellite platforms. The ASTER contribution is the Level-1B product over the United States and Territories. These data are populated on a two-year rolling archive basis. This means that an ASTER L1B data set older than 2 years (730 days since its acquisition) is removed from the Data Pool. MODIS collections span three varieties: Daily products are retained for an 8-day period; Composite products include at least one year's retention of 8- and 16-day products; Science collections are ad hoc temporary data sets staged and removed in short order based on special requests. They also include certain permanent collections.

There are two basic methods to access and acquire Data Pool products via FTP. The first is a search mechanism with a simple "drill-down" process to quickly locate data of interest. Browse and metadata are viewable directly in any Internet browser. The second is a direct access to the FTP directories for downloading. If you are new to the Data Pool, please read the Help and Release Notes for a quick overview. The Data Pool contents are a subset of the Warehouse Inventory Search Tool (WIST). In case you missed acquiring any particular data granule within its retention period, please request the same from WIST.
