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

2011-04-13: GHRSST Newsletter No. 3 for April 2011 available
The third monthly GHRSST newsletter is now available through the GHRSST Project Office website at http://www.ghrsst.org/news/q/date/2011/04/13/ghrsst-newsletter-no-3/.

2011-03-25: EUMETSAT Launching IASI SST L2PCore
GHRSST is pleased to announce the launch of the new Infrared Atmospheric Sounding Interferometer (IASI) Sea Surface Temperature (SST) product, identified as IASI SST L2PCore. The product has been designed in accordance with the specifications defined by GHRSST, and will initially contain SST, Single Sensor Error Statistics (SSES), quality levels, flags and collocated model surface winds. Quality levels for this product have been defined by stratifying against integrated water vapor, calculated by integrating IASI water vapor profiles from the IASI Level 2 products with pressure level information. SSES for each quality level have been derived using a matchup database of IASI SSTs collocated with in situ buoy SST observations (built up following GHRSST guidelines) spanning from 1 April to 28 September 2010. EUMETSAT plans to recalculate the SSES every 6 months. The IASI SST L2PCore product will be available via the EUMETSAT Data Centre and the FTP server, for which registration is possible on the EO Portal. Upon registration users will receive information on accessing the data on the FTP server. Test data of this product is currently available via FTP at: ftp://ftp.eumetsat.int/pub/EUM/out/OPS/User/IASI_SST_L2PCORE/.

2011-02-16: Several updates to GHRSST products to be ingested into LTSRF
Beginning today, the GHRSST LTSRF at NODC will be processing a large volume of backlogged GHRSST data, ingesting it into the archive, and making it available online. This backlog contains updates to data from several GHRSST products, and may include the addition of new data files, removal of old data files, one-to-one replacement of existing data files, or some combination of these. Many of these updates have already been available via the GHRSST GDAC, but have remained offline at the LTSRF while we determined the best way to clearly capture and document such updates. If you have downloaded GHRSST data and would like to ensure that you have the most recent version of the data, please check the following: For users accessing data through the various LTSRF web services (HTTP, FTP, OPeNDAP, THREDDS) there will be an "accession update log" text file in the root GHRSST directory that contains a list of daily directories affected by the updates. This list will also contain corresponding NODC accession numbers and the data of the update, and will capture all changes to the GHRSST LTSRF collection moving forward. For users accessing data through the NODC Ocean Archive System, information about each update will be captured in the journal.txt file in the "about" directory of the accession. Note: ALL GHRSST data, old and new, will still be available through the NODC Ocean Archive System. For questions or concerns about this process, please contact the LTSRF. For more information about updates to individual products, please contact the Technical Contact for the relevant GHRSST RDAC.

2010-11-15: New Global 1km Level 4 product from NASA JPL now available through GHRSST
The Multiscale Ultrahigh Resolution (MUR) blended sea surface temperature (SST) product has been updated to version 1. This is a daily 1 km resolution product funded by the NASA MEaSUREs program to meet the goals of an accurate and consistent retrospective Level 4 SST record, for US coastal regions initially. The output data sets are made to GDS 2.0 specifications for Level 4 netCDF. Some of the improvements and differences of version in comparison to the previous version 0 (beta) are: 1) uses only nighttime input data from MODIS Aqua, Terra and AMSRE; 2) includes nighttime AVHRR data; 3) improves sensor bias corrections; and 4) improves spatial dependence of interpolation parameters. This product is produced at the NASA Jet Propulsion Laboratory by Dr. Mike Chin. The data for 2008-2010 are available from the GDAC at ftp://podaac.jpl.nasa.gov/GHRSST2/data/L4/NCAMERICA/JPL/MUR/, and will be available from the LTSRF soon. Any questions concerning this product can be addressed to ghrsst@podaac.jpl.nasa.gov.

2010-10-28: Envisat mission extension - update on AATSR data availability

Further details can be found on the meeting webpage at http://www.ghrsst.org/Joint-DVWG,-HL-TAG-and-ST-VAL-Workshop-2011.html.

2010-10-13: Envisat mission extension to cause gap in AATSR data
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. A statement confirming the quality of AATSR data after the change in orbit will be made at the beginning of December, 2010. Updates on data quality or changes to the implementation schedule will be announced via the GHRSST Program Office website as well as the LTSRF RSS News Feed as soon as they are known. For more information, refer to the full article on the GHRSST Program Office website at http://www.ghrsst.org/Envisat-mission-extension-%E2%80%93-implications-for-AATSR-data-News.htm.

As of January 23, 2007, the NODC LTSRF contains 9897 accessions! One "accession" contains the data from one Regional Data Assembly Center, from one sensor, for one day. These accessions make up nearly 3 Terabytes of data, and every day more data are coming into the archive. Currently, data are available back to 2005 but eventually the archive will contain reprocessed GHRSST-formatted data back to 1985 and then late 1981.

2007-01-22: GHRSST Article for Bulletin of the AMS accepted
An article describing the GHRSST project has been accepted for publication in the Bulletin of the American Meteorological Society. No word yet on when it will appear in print, but stay tuned!

2006-10-26: GHRSST Data Now Being Formally Archived at NODC
NODC has successfully completed the first major phase of its work to develop the GODAE High Resolution SST (GHRSST) Long Term Stewardship and Reanalysis Facility (LTSRF, http://ghrsst.nodc.noaa.gov). This first phase was to implement the archive and long term stewardship aspects of the system. NODC now automatically acquires, generates metadata, and formally archives all of the GHRSST satellite SST data sets on a daily basis. These data are all available via ftp (ftp://data.nodc.noaa.gov/pub/data.nodc/ghrsst/), http (http://data.nodc.noaa.gov/ghrsst/), and OPeNDAP (http://data.nodc.noaa.gov/cgi-bin/nph-dods/ghrsst/) . Currently, there are over 7500 accessions in the NODC archive system for GHRSST Level 2P and Level 4 SST data, all of which are searchable via the NODC Ocean Archive System (http://www.nodc.noaa.gov/Archive/Search) as well. There are approximately 1 terabyte of compressed data in the archive now (about 20 terabytes uncompressed) spanning 2005 and 2006 for AMSR-E, AVHRR-16, AVHRR-17, AVHRR-18 (GAC and LAC/HRPT) , MODIS Aqua, SEVIRI, AATSR, and TMI. MODIS Terra and GOES SSTs will be available soon as well. Approximately 14 new accessions (each of which consists of satellite SST data produced from one GHRSST Regional Data Assembly Center from one sensor for one day) are added each day to the archive. The next phase of NODC's effort is to develop in association with the international community the ability to reprocess GHRSST data to create global, high resolution gap-free reanalysis climate data records for SST. NODC will also continue to augment and improve its archive, access, and stewardship services for GHRSST data and information.

2006-01-26: GHRSST presented to NOAA NPOESS Data Exploitation Team in Suitland, MD
Ken Casey gave a short briefing to the NOAA NPOESS Data Exploitation Team. The goals of the presentation were simple: to introduce GHRSST to the NOAA program that will be handing tailored products from NPP and NPOESS. It is likely that in some way this team would be involved in any future attempts to get SST data from VIIRS and CMIS (the future sensors to fly on NPP and/or NPOESS) into a GHRSST compatible format. The presentation is provided below in PowerPoint and PDF formats:

2005-11-07: NOAA GHRSST Meeting held in Silver Spring MD (SSMC3 - Room 4817)
On November 7, 2005, members of the NOAA SST community met in Silver Spring to discuss the current status and future plans of the GHRSST international framework. The goals of the meeting were to inform the NOAA community about NOAA's current involvement in GHRSST, and to discuss possible future roles for the various NOAA components that deal with SST data production and management as GHRSST grows into a long-term, sustained system. Presentation files in PowerPoint (~30 MB) and PDF (~3 MB) used at the meeting are as follows:

2005-10-21: GHRSST Reanalysis Project and Pathfinder Climate Data Records Featured at MARCDAT-II
During the week of October 17, Ken Casey, Chair of the GHRSST Reanalysis Technical Advisory Group, and Craig Donlon, Director of the GHRSST Project Office, gave talks on the GHRSST reanalysis effort and the use of the AVHRR Pathfinder Climate Data Records as a fundamental input to the GHRSST reanalysis system at the Second International Workshop on Advances in the Use of Historical Marine Climate Data (MARCDAT-II). The conference was held at the UK Met Office in the Exeter, UK. GHRSST featured prominently at this meeting as the means of delivering climate-quality satellite-based SST data to the international community.

2004-10-20: NODC - PO.DAAC Workshop on Establishing the LTSRF
A meeting was held at NODC on October 20, 2004, with PO.DAAC personnel to establish key technical components of the NODC/PO.DAAC interface. This meeting was a critical first step in establishing the GHRSST Long Term Stewardship and Reanalysis Facility (LTSRF) at NODC. A meeting report and related documents are available below:
