News 2016 02 16: pps is now also being run on ears-avhrr data from Metop-B and NOAA-19. This is complementing the direct readout data in situations of antenna conflicts.

News 2015 04 21: pps version 2014 with patch-20150327 installed. This patch provides a globally improved cloudmask. It was a result of extensive testing and tuning initiated by findings in December 2014 by the CMSAF in preparations for going into their CLARA-A2 dataset processing. In summary the improvements cover: Generally increased POD cloudy and Hitrate; Improved snow/ice detection. Less cirrus over water and cold water are classed as ice/snow. Specially at coast; Improved detection of small cumulus; Less false clouds: 1) in areas with fractional clouds. 2) over desert. 3) in Arcitc/Antarctic. 4) in sunglint conditions.

News 2015 02 12: pps version 2014 installed. Now also Terra and Aqua MODIS data are being processed with PPS. The PPS Task Manager is now descoped, and a new framework for polar satellite data processing has been introduced, which builts on Pytroll using message based processing.

News 2013 09 24: EARS -NWC validation and monitoring pages added to this site. Go to the EARS-NWC reference validation page to monitor the recent performance of the EARS-NWC products against the reference production at SMHI on DR data from Norrköping.

News 2013 06 28: The real time processing on the Metop-B gds via EUMETCast reception was resumed on Wednesday the 26th of June, after more than 3 weeks inerruption due to internal upgrades at SMHI of the ECMWF data streams. Unfortunately we discovered a bit late in the upgrade process that the CTTH product needed a small patch (is available on the Help desk since June 19) and was unable to patch the PPS in time before vacations. This means the CTTH demonstration has been put on halt until further notice. We expect to resume it in late August.

News 2013 03 26: Real time processing of Metop-B on both locally received AVHRR data and on Metop gds via EUMETCast reception introduced in operations. Check it out at the dr Product Demonstration pages and the gds Product Demonstration pages.

News 2013 02 21: pps patch to accomodate Metop-B released to users. The AAPP-v7.4 plus the patch released by the nwpsaf on February 8, 2013 (see the forum) is needed.

News 2012 12 17: Suomi npp satellite added in operations. All pps products now available also on VIIRS. See the Product Demonstration pages. First Suomi NPP scene in operations was orbit number 5903 at around 10:28 UTC December 17, 2012. The Suomi NPP satellite is currently being received at Norrköping with low priority relative to the NOAA satellites, as the RDR to SDR data acquisistion is not yet meeting reasonable timeliness requirements. When we have set up RT-STPS to run on real time CADU streaming and CSPP to run on granules using several instances in parallel (hopefully early 2013) we will raise Suomi NPP priority

News 2012 07 02: This web site updated - now consistent with the new production based on version 2012 of the Polar Platform System (pps). This includes the visualisation of the parameters from the Cloud Physical Properties (cpp) algorithm.

News 2012 06 11: pps version 2012 now in production at SMHI.

News 2012 05 07: Version 2012 of the Polar Platform System (pps) is now available through the nwc saf Help Desk. See release notes for an overview of changes since last version.

News 2011 02 16: Version 2010 Patch 2 now in operation at the reference system at SMHI.

News 2010 11 23: Patch 2 of version 2010 of the Polar Platform System (pps) is now available through the nwc saf Help Desk. This patch is valuable mainly for gac-processing. It also contains a bug correction related to re-projection and resampling. Previously some re-projection operations did result in location errors of half a pixel. See release notes for an overview of changes since last version.

News 2010 11 08: New web-site. New look, correct logo-types, updated information, and easier navigation.

News 2010 08 24: Patch 1 of version 2010 of the Polar Platform System (pps) is now available through the nwc saf Help Desk. This patch is valuable mainly for gac-processing and grib2-usage. See release notes for an overview of changes since last version.
