Data Access within the GHRSST-PP

Data products within the GHRSST-PP are formatted as netCDF files according to the CF convention. Example data read software is provided to read GHRSST-PP data files which can be downloaded from the Data Tools page. Two types of satellite SST products are generated: L4 SST analysis products and L2P SST integrated observation products. L2P data are ideal as input to data assimilation systems and SST analysis systems as they preserve the original SST values but provide additional uncertainty estimates and a suite of ancillary data to aid interpretation of the SST observations themselves. Data are generated at both Regional Data Assembly Centres (RDAC) sites and at a single Global Data Analysis Centre ( GDAC) located at the NASA PO.DAAC. In the coming months, all GHRSST-PP data will be served by the JPL GDAC with a mirror GDAC located in Europe as part of the European Commission MERSEA project.

This page describes where to find and access GHRSST-PP data data products.

Finding the data you want - the GHRSST-PP MMR

The GHRSST-PP has developed a Master Metadata Repository (MMR) system that catalogues all data files that have been ingested by the GHRSST-PP GDAC system. The MMR is a data discovery tool implemented as a searchable web based interface designed to allow users simple and easy lookups to the GHRSST-PP data sets. The GHRSST-PP prototype MMR system is now live and all data records can bve searched on-line using a simple user interface.
