On Monday 20th of March the SolR back-end for the metadata catalogue of the data portal will be changed.

Some major modifications will be present, including changes of metadata identifiers for some of the records.

A namespace prefix no.met.adc for all records managed by the Arctic Data Centre (adc.met.no) is now added.

Some records might be missing at the beginning, but we are working on filling these gaps.

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.

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 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).

Information from the CNR Antarctic YOPP catalogue is now harvested into the YOPP data catalogue.

Information of MOSAIC datasets are now routinely harvested from PANGAEA and ingested in the YOPP Data Catalogue.

Harvesting issues with NIPR-ADS are now solved and harvesting is back to normal.

Information on datasets generated in the context of the Polar Amplification Model intercomparison Project (PAMIP) is currently under ingestion in the data catalogue. The first datasets to be ingested are the APPLICATE datasets. A list of relevant datasets is available at https://pcmdi.llnl.gov/CMIP6/ArchiveStatistics/esgf_data_holdings/PAMIP….

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.
