Merged Observatory Data Files

By steingod | Mon, 08/22/2022 - 17:08

The team creating the Merged Observatory Data Files (MODF) to be compared with the Merged Model Data Files (MMDF) of the YOPP Site Model Intercomparison (YOPP SiteMIP) activity are working hard to complete files. Some test files have been made and will be made dicsoverable in the catalogue, these files will however be replaced with updated versions in the near future so please do not use these files for publications yet. Please wait for the updated files. The files are however good for tesing purposes although they have some issues.

Updated version of the H-K Table

By steingod | Sat, 04/16/2022 - 23:17

An updated version of the H-K Table was published today.  Version 1.2 corrects time variables that were present in the Version 1.1 pdf but not the json files; adds a variable for upward_air_velocity; tweaks attributes for a few existing variables (see the Lineage section for details); and adds license and citation information.  Many of these changes came about due to discussions associated with last week's hands-on workshop in Stockholm; thanks to all who helped in this fashion!

The H-K Variable SchemaTable developed for the YOPPsiteMIP (1.1)

The YOPP Supersite-Model Intercomparison Project (YOPPsiteMIP) is linking observations from selected land-based observatories and ship-based field campaigns with high frequency co-located outputs from numerical weather prediction models during the Special Observing Period during the Year of Polar Prediction (YOPP, May 2017 to June 2019).

YOPPSiteMIP data from Meteo-France

By steingod | Thu, 03/25/2021 - 10:06

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.

NRL has contributed YOPP SiteMIP data from Navy-ESPC

By steingod | Wed, 02/24/2021 - 18:02

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.

Arome-Arctic YOPPSiteMIP data available

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:


ECCC YOPP SiteMIP data available

By steingod | Wed, 12/11/2019 - 20:33

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).

ECMWF IFS YOPP SiteMIP data available

By steingod | Wed, 08/28/2019 - 17:26

ECMWF IFS for YOPP supersites are now available at http://thredds.met.no/thredds/catalog/alertness/YOPP_supersite/ifs-ecmw…. 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.
