GHRSST DSD Metadata Records The following are links to Dataset Description (DSD) XML metadata records for all GHRSST L2P/L3/L4 products.These records, in conjunction with the granule File Record (FR) metadata, describe the productcollections. The GDAC uses these DSD and FR records together to construct the FGDC metadata records accessible via the GHRSST Longterm Stewardship and Reanalysis Facility (LTSRF; http://ghrsst.nodc.noaa.gov).
