ECMWF IFS for YOPP supersites are now available at http://thredds.met.no/thredds/catalog/alertness/YOPP_supersite/ifs-ecmwf.... Preparation of discovery metadata for inclusion in the YOPP Data Portal is in progress. ECMWF is not responsible for any use that may be made of the YOPPsiteMIP dataset.

Information on YOPP datasets hosted by the Arctic Data Archive System (ADS) of the National Institute for Polar Research in Japan is now included in the searchable data catalog for YOPP.

The search interface has been updated. Now the map used in the search box supports more map projections, including a southern and northern hemisphere map. Furthermore, the search interface has been further restructured and prepared for more faceted searchs (e.g. by institutions) in the future. The business logic supproting transformations has also received some upgrades, but many of these will first be fully visible once the backend services are updated as well.

The NOAA National Centers for Environmental Information (NCEI) have developed a number of templates following the CF and ACDD conventions as requested by the YOPP guidelines. Further information on these templates are available at https://www.nodc.noaa.gov/data/formats/netcdf/v2.0/.
