Ship-borne radiosonde observation data from Korea Polar Prediction System (KPOPS)

By laraf | Tue, 10/08/2019 - 10:08

Data from the Yopp-endorsed project KPOPS are now available.

The radiosonde balloon sounding observations were performed from 5 August 2019 to 17 September 2019 to obtain the Arctic Ocean high-resolution atmospheric vertical profiles along the IBRV Araon cruise track at four times daily intervals (00, 06, 12, 18UTC). The data include vertical profiles of temperature, humidity, pressure, wind speed and wind direction up to about 30km. The data have been used for the data assimilation of the KOPRI Arctic weather forecast system.

ECMWF IFS for YOPP supersites are now available at…. 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.

Updates to the search facility for datasets

By steingod | Tue, 08/06/2019 - 22:16

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.

Meteo-France data for the YOPPsiteMIP SH

By steingod | Fri, 06/21/2019 - 14:08

Meteo-France has extracted ARPEGE data over the Southern Hemisphere YOPP supersites. These data are now available on the ftp site (user: yopp / password: Arpege). Change working directory to YOPP-SH where NetCdf-MIP contains the output for the supersites using the exact  same format as used for the YOPP-NH super site (now available on the YOPP Data Portal). In addition 3D fields are output in a GRIB format (under YOPP-SH/3DFIELDS) as well. Inclusion of the SH data as NetCDF/CF in the YOPP Data portal is currently in progress.

YOPP supersites data from ARPEGE

By steingod | Tue, 05/28/2019 - 01:16

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… (push "search").

Data extracted from WMO GTS

By steingod | Tue, 05/28/2019 - 00:38

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.
