The first PAMIP data are now available through https://pcmdi.llnl.gov/CMIP6/ArchiveStatistics/esgf_data_holdings/. These data are important for PPP and YOPP. Further information is available in https://www.geosci-model-dev.net/12/1139/2019/.

CNRM, University de Toulouse, Météo-France, CNRS, Toulouse, France has provided YOPP Model Site Intercomparison data for the Arctic Supersites. These data are indexed in the catalogue and the results are available through https://yopp.met.no/metadata_search/?quid=3d5a7b4b0a927c64ef1d0f6d5759ba... (push "search").

The Norwegian Meteorological Institute is extracting public data from WMO GTS and converting these to NetCDF/CF. This is being done for SYNOP, TEMP and SHIP data. Some of these data have been indexed in the catalogue with discovery metadata (SYNOP), but not all. Furthermore, work is in progress on the TEMP data to support high resolution profiles.

Several of the YOPP modelling teams have been working on extraction of data over YOPP supersites. Information from two models in the Arctic, ARPEGE and ECCC-CAPS are now available in NetCDF/CF through a THREDDS Data Server. Work is in progress to make these data searchable through the YOPP catalogue. The data is available at http://thredds.met.no/thredds/catalog/alertness/YOPP_supersite/catalog.html.
