ECHO has been replaced by the Common Metadata Repository (CMR), a high-performance, high-quality, continuously evolving metadata system that catalogs all data and service metadata records for the EOSDIS system and will be the authoritative management system for all EOSDIS metadata.
The information contained within this ECHO wiki is now archived for historical reference. Please navigate to the CMR wiki pages, or to the CMR Overview page on Earthdata.
