In order to serve the Land Processes Distributed Active Archive Center (LP DAAC) user community more effectively, the LP DAAC will transition from FTP to HTTP for ASTER and MODIS downloads.
The HTTP updates are designed to increase performance and improve security during data retrieval. Both FTP and HTTP capabilities will be available during this transition. Users of LP DAAC data should plan to update any automated scripts for LP DAAC data retrieval. LP DAAC will continue to provide both protocols until further notice, however we highly recommend users begin the migration to HTTP as soon as possible to ensure data delivery.
Please contact LP DAAC User Services with any questions at lpdaac@usgs.gov.
