2011-05-24: AVHRR Pathfinder Version 5.2 Data Completes Public Review

24 May 2011 09:00:00 GMT

The GHRSST Long Term Stewardship and Reanalysis Facility at the NOAA National Oceanographic Data Center thanks everyone who participated in the public review and comment period for AVHRR Pathfinder Version 5.2 (PFV52). Numerous minor comments and questions were received but no major issues identified with the draft data set. The Pathfinder team at NODC and the University of Miami is making final adjustments based on these comments and plans to release the full PFV52 data set prior to the 12th GHRSST Science Team meeting, which is being held 27 June to 1 July 2011 in Edinburgh, Scotland. Thank you for helping us create the best possible AVHRR-based climate data record for SST!



2011-05-02: AVHRR Pathfinder Version 5.2 Data Released for Public Review

02 May 2011 09:00:00 GMT

The GHRSST Long Term Stewardship and Reanalysis Facility at the NOAA National Oceanographic Data Center announces a public review period for the AVHRR Pathfinder Version 5.2 (PFV52) sea surface temperature product. PFV52 was computed using an entirely modernized system, based on SeaDAS and incorporating several key changes as we prepare for the future Version 6 (PFV6) data set (no release has yet been established for PFV6). These changes include the use of an entirely new land mask, a modified grid, and the inclusion of sea ice and wind speed ancillary data to support the use of the SST data. Importantly, the new PFV52 data are provided in netCDF-4 (classic model, with internal compression and chunking) and are nearly 100% compliant with the GHRSST Data Specification Version 2.0 (http://data.nodc.noaa.gov/pathfinder/PFV52_PublicReview/GDS_TechSpecs_v2.0.pdf) for L3C products. These data deviate from that standard only in that the sses_bias, sses_standard_deviation, and sst_dtime variables are empty and the aerosol_dynamic_indicator variable is not yet present. We have made a collection of data spanning 2005-2010 (some days are presently missing) available for download via the following services: HTTP: http://data.nodc.noaa.gov/pathfinder/PFV52_PublicReview; FTP: ftp://ftp.nodc.noaa.gov/pub/data.nodc/pathfinder/PFV52_PublicReview; and THREDDS: http://data.nodc.noaa.gov/thredds/catalog/pathfinder/PFV52_PublicReview. We ask you to review and examine these data, then send questions, comments, or concerns to Kenneth.Casey@noaa.gov by 11:59 PM EST on Monday, 23 May 2011. We will address as many problems identified through this public review as we can, prior to production of the full PFV52 data set. We expect to release the full PFV52 data set prior to the 12th GHRSST Science Team meeting, which is being held 27 June to 1 July 2011 in Edinburgh, Scotland. Thank you for helping us create the best possible AVHRR-based climate data record for SST!

2010-10-13: Envisat mission extension to cause gap in AATSR data

13 Oct 2010 09:00:00 GMT

The Envisat mission extension scenario will be implemented later this month, which will lower the spacecraft altitude and allow the orbit inclination to drift. The fuel saved from the drifting orbit should allow the mission to continue for another three years. Due to this maneuver, all data distribution from Envisat will stop completely between October 22nd and November 2nd, 2010. Once data flow is resumed, there should be no change in AATSR data quality and GHRSST users should continue to use AATSR data as normal.
