The Data Pool is the publicly available portion of the LP DAAC online holdings. Data Pool provides a more direct way to access files by foregoing their retrieval from the nearline tape storage devices. All Data Pool holdings are available at no cost to the user.
MODIS Composites are mostly online and will be completely online in the near future. Many of the MODIS dailies are online and will be completely populated during the longer term.
The most recent two years of ASTER Level-1B products for the U.S. and territories is available for Data Pool access. Please see the SWIR Avisory Alert.
Download via FTP
This Data Pool access method allows users to navigate directly to the product collection of interest and then to the product period(s) of interest within the online file structure. Then, the HDF-EOS files, XML metadata files, and JPG browse images (if available) may simply be downloaded by FTP.
Direct Search Interface
This Data Pool access method allows users to select a collection interest, then define spatial and temporal filters to return a listing of data sets meeting their criteria. Data files returned from this search are exposed to limited on-the-fly reformatting, reprojection, and subsetting services (see Reformat tab, below).

The Data Pool HDFEOS-to-GeoTiff (HEG) tool provides the ability to reformat, reproject, or spatially subset data available via the Data Pool from the Direct Search Interface. The Data Pool HEG services are completed prior to product distribution, and may be applied only to products in the Data Pool.
The following tables summarize LP DAAC Data Pool HEG capabilities and available outputs for supported instruments.
