The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | 4 km AVHRR Pathfinder v5.0 Global Day-Night Sea Surface Temperature Monthly and Yearly Averages, 1985-2009 (NODC Accession 0077816) |
| Abstract: | This data set contains a set of monthly and yearly global day-night sea surface temperature averages, derived from the AVHRR Pathfinder Version 5 sea surface temperature cloudscreened data set (http://pathfinder.nodc.noaa.gov) in GeoTIFF format. The AVHRR Pathfinder SST data sets provide the longest, most accurate, and highest resolution consistently-reprocessed SST climate data record from the AVHRR sensor series. These data files were produced to facilitate the utilization of high resolution Pathfinder v5.0 sea surface temperature data within geographic information system (GIS) software. These day-night combined monthly and yearly means were produced from cloud-screened day-night monthly full resolution files of Pathfinder SST data from 1985-2009. The data are available for download at http://accession.nodc.noaa.gov/0077816 or through the NODC Geoportal at http://geoid:8080/geoportal/catalog/main/home.page. The original .HDF files are archived at the National Oceanographic Data Center under separate accession numbers. The GeoTIFF SST averages were assigned projection GCS_WGS_1984. In addition, browse images in PNG format with an associated KML file for each year are included with these data as well as detailed metadata. |

| Supplementary information: | Please acknowledge the use of these data with - The Pathfinder Version 5.0 SST Data were provided by the NOAA/National Oceanographic Data Center at URL: http://pathfinder.nodc.noaa.gov A land mask is not included with these data. The NODC does not routinely provide land masks in its products. A suggested shoreline is the Global Self-consistent Hierarchical High-resolution Shoreline Database (GSHHS) available at http://www.ngdc.noaa.gov/mgg/shorelines/gshhs.html and http://www.soest.hawaii.edu/pwessel/gshhs/index.html (Wessel, P., and W. H. F. Smith, A Global Self-consistent, Hierarchical, High-resolution Shoreline Database, J. Geophys. Res., 101, 8741-8743, 1996.) During the averaging process, NODATA pixels were not included; data pixels with no corresponding data pixels were maintained as their original number to maximize the amount of available data. The complete product development process is available at http://www.nodc.noaa.gov/SatelliteData/pathfinder4km/PFV5_GIS_tutorial.html. The NODC collection of value-added, cloud-screened products in HDF4 were developed from original AVHRR Pathfinder files archived at the NODC. These products contain daytime, nighttime, and day-night averaged data of quality flags 4-7, as well as standard deviation and pixel count information. They have been produced from the original Pathfinder Version 5.0 data by NODC for Daily, 5-day, 7-day, and monthly temporal averages at 4km and one degree spatial resolution, as well as five degree spatial resolution for monthly products. The monthly full resolution products were utilized to develop the final GIS files of this data set. While these cloudscreened files are derived from official Pathfinder Version 5.0 data, they are NOT part of the official NODC Version 5.0 collection. To access this collection use the Version5.0/ directory at the NODC's Pathfinder section of the website. For more information on their provenance, contents, or relationship to official Pathfinder Version 5.0 data, please contact Ken Casey at Kenneth.Casey@noaa.gov. NODC December 2010 |
