YOPP datasets

Meteo-France has a FTP site with all YOPPSiteMIP data produced. Further information is provided in the attached PDF document. These data will eventually be included in the YOPP data catalogue, but in the mean time they are also available directly from the FTP site.

The Naval Research Laboratory (NRL) has committed data from the Navy Earth System Prediction Capability (Navy‐ESPC) to YOPPSiteMIP datasets. the data are directly available at https://thredds.met.no/thredds/catalog/alertness/YOPP_supersite/navy-es… and addition of discovery metadata to the YOPP Data catalogue is in progress.

From the YOPP news section at https://www.polarprediction.net/news/:

MET Norway and the YOPP International Coordination Office are publishing the first of a series of video tutorials on how data can be searched in the YOPP Data Portal. YOPP maintains this metadata portal as an overview archive for Arctic and Antarctic data generated during the Year of Polar Prediction. The community is invited to find YOPP data from a specific area or time to use for their various purposes.

The Norwegian Meteorological Institute has uploaded YOPPSiteMIP data for YOPP supersites Ny-Ålesund and Sodankylä that are within the geographical domain of the Arome-Arctic model. Data are searchable and also directly available at:

The HydroMeteorological research Center of Russia has made YOPPSiteMIP data from the SL-AV model available for YOPP supersites.

Environment and Climate Change Canada (ECCC) has developed the Canadian Arctic Prediction System (CAPS). CAPS has been runned in operation at the Canadian Meteorological Service in experimental mode since February 2018. Prior to the 28th of June 2018 (included), CAPS was runned uncoupled, whereas since the 29th of June 2018 (included), CAPS was coupled with the Canadian Regional Ice and Ocean Prediction system (RIOPS).

During the Cinese Arctic Cruise in 2018 frequent radiosoundings were launched in support of YOPP Special Observation Period along the path of XUELONG ice breaker. The radiosoundes were launched 2-3 times per day from July 28th to September 3rd in the Arctic Ocean and a total of 76 soundings data were shared through WMO GTS in BUFR format. These BUFR files are now available for download at:

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.

Radiosonde and SYNOPs for Baranova and Tiksi stations for the YOPP SOP NH1 and NH2 are now available at

Data are yet not indexed in the YOPP catalogue. Work is in progress to index these datasets.
