The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is part of NASA’s Earth Observing System Data and Information System (EOSDIS). PO.DAAC’s purpose is to store oceanography and climatography related data obtained by NASA. PO.DAAC also serves as a pathway to other related archives and provides relevant tools making their datasets easily consumable and applicable. NASA’s PO.DAAC Granules Metadata API retrieves granule metadata from PO.DAAC's dataset. The Granules Metadata API can retrieve metadata for one given granule or a list of granules added within 24 hours.
