Title: Sea surface temperatures from AVHRR
Abstract:
The production of these AVHRR L2P data is a NEODAAS activity in collaboration with the UK National Centre for Ocean Forecasting (NCOF). NEODAAS-Dundee acquires approx. 15 AVHRR HRPT passes per day over NW Europe and Arctic, each approx. 15 minutes duration. These are immediately transferred to NEODAAS-Plymouth where they are processed into SST products and converted to L2P. This metadata record is a collection-level description for sea surface temperatures from AVHRR data for all time periods. Select time periods and files are accessible through the servers detailed in the DISTRIBUTION SECTION of this record.
Supplemental_Information:
Entry ID: NEODAAS-L2P-AVHRR19_L Projection_Information: Projection Type: Satellite native swath Ellipsoid_Type: Other Projection Details: Geolocation information included for each pixel Data Resolution: Latitude resolution: 1.1 km Longitude resolution: 1.1 km The temporal resolution: Revisit four times each day (night and daytime passes) This metadata record was generated from an original data set description (DSD) record in DIF format: <http://www.ghrsst.org> Reference: Information about the AVHRR processing system at NEODAAS can be found at: <http://www.npm.ac.uk/rsdas/faq/> and in this conference paper: Miller P, Groom S, McManus A, Selley J and Mironnet N.

    Other_Citation_Details:
    The Global Ocean Data Assimilation Experiment (GODAE) is an international collaboration for ocean forecasting activities which, in 2002, initiated a GODAE High Resolution SST Pilot Project (GHRSST-PP) to address an emerging need for accurate high resolution sea surface temperature (SST) products. The Pilot Project was replaced by the Group for High Resolution SST (GHRSST) in 2009. The aim of the GHRSST is to provide the best quality sea surface temperature data for applications in short, medium and decadal/climate time scales in the most cost effective and efficient manner through international collaboration and scientific innovation.

  7. How does the data set describe geographic features?

    Entity_and_Attribute_Overview:
    Within the GHRSST DIF-style metadata framework, every data set type is described by a static Data Set Description (DSD), and the individual netCDF files making up that dataset are described by dynamic File Records (FR). These FRs contain the spatial and temporal domain contained in each data file. The DIF-style metadata (the DSD and its children FRs) are converted to a single FGDC record for each NODC GHRSST accession, which can consist of several discrete data files. This conversion is accomplished using an XML stylesheet which builds a framework FGDC record based on the DSD, and populates it with one Entity for each data file based on the FRs. These Entities are given three Attributes: Latitude, Longitude, and Time. The Range Domain Minimum and Maximum elements within each of those Attributes are use to describe the spatial and temporal domain contained in the data file. So, for example, the Range Domain Minimum for the Attribute Latitude corresponds to a South Bounding Coordinate for that Entity.
