The AVHRR is a space-borne scanning sensor on the National Oceanic and Atmospheric Administration (NOAA) family of Polar Orbiting Environmental Satellites (POES) having a operational legacy that traces back to the Television Infrared Observation Satellite-N (TIROS-N) launched in 1978. AVHRR instruments measure the radiance of the Earth in 5 (or 6) relatively wide spectral bands. The first two are centered around the red (0.6 micrometer) and near-infrared (0.9 micrometer) regions, the third one is located around 3.5 micrometer, and the last two sample the emitted thermal radiation, around 11 and 12 micrometers, respectively. The legacy 5 band instrument is known as AVHRR/2 while the more recent version, the AVHRR/3 (first carried on the NOAA-15 platform), acquires data in a 6th channel located at 1.6 micrometer. Typically the 11 and 12 micron channels are used to derive SST sometimes in combination with the 3.5 micron channel. The NOAA platforms are sun synchronous generally viewing the same earth location twice a day (latitude dependent) due to the relatively large AVHRR swath of approximately 2400 km. The highest ground resolution that can be obtained from the current AVHRR instruments is 1.1 km at nadir. AVHRR data are acquired in three formats: High Resolution Picture Transmission (HRPT), Local Area Coverage (LAC), and Global Area Coverage (GAC). HRPT data are full resolution image data transmitted to a ground stations as they are collected. LAC are also full resolution data, but the acquisition is prescheduled and recorded with an on-board tape recorder for subsequent transmission during a station overpass. This particular dataset is produced from GAC data that are derived from an on-board sample averaging of the full resolution global AVHRR data. Four out of every five samples along the scan line are used to compute on average value and the data from only every third scan line are processed, yielding an effective 4 km resolution at nadir. Further binning and averaging of these pixels results in a final dataset resolution of 8.8 km.' description_attribution: http://podaac.jpl.nasa.gov/dataset/NAVO-L2P-AVHRR17_G display_name: GHRSST Level 2P Global Bulk Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-17 satellite produced by NAVO doi: ~ end_time: 2009-07-06T15:00:00 files: - display_name: NAVO-L2P-AVHRR17_G.jpg file: d8/68/30ebaec1a4b34c513a0a0c2fa5dd/NAVO-L2P-AVHRR17_G.jpg href: http://data.globalchange.gov/assets/d8/68/30ebaec1a4b34c513a0a0c2fa5dd/NAVO-L2P-AVHRR17_G.jpg identifier: f35df8d8-bfa9-4009-9e12-07e04707d55b landing_page: http://podaac.jpl.nasa.gov/Podaac/thumbnails/NAVO-L2P-AVHRR17_G.jpg location: ~ mime_type: image/jpeg sha1: 86dbd6a81dfe1472dfb428638ec3e48feef92a1b size: 36318 thumbnail: d8/68/30ebaec1a4b34c513a0a0c2fa5dd/.thumb-f35df8d8-bfa9-4009-9e12-07e04707d55b.png thumbnail_href: http://data.globalchange.gov/assets/d8/68/30ebaec1a4b34c513a0a0c2fa5dd/.thumb-f35df8d8-bfa9-4009-9e12-07e04707d55b.png type: file uri: /file/f35df8d8-bfa9-4009-9e12-07e04707d55b url: http://data.globalchange.gov/assets/d8/68/30ebaec1a4b34c513a0a0c2fa5dd/NAVO-L2P-AVHRR17_G.jpg href: http://52.38.26.42:8080/dataset/nasa-podaac-navo-l2p-avhrr17_g.yaml identifier: nasa-podaac-navo-l2p-avhrr17_g instrument_measurements: - dataset_identifier: nasa-podaac-navo-l2p-avhrr17_g display_name: national-oceanic-and-atmospheric-administration-17/advanced-very-high-resolution-radiometer-3/nasa-podaac-navo-l2p-avhrr17_g instrument_identifier: advanced-very-high-resolution-radiometer-3 platform_identifier: national-oceanic-and-atmospheric-administration-17 type: instrument_measurement lat_max: 80 lat_min: -70 lon_max: 180 lon_min: -180 name: GHRSST Level 2P Global Bulk Sea Surface Temperature from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-17 satellite produced by NAVO native_id: NAVO-L2P-AVHRR17_G parents: [] processing_level: ~ publication_year: ~ references: [] release_dt: 2011-01-21T17:10:13 scale: ~ scope: ~ spatial_extent: ~ spatial_ref_sys: ~ spatial_res: ~ start_time: 2006-06-21T06:24:32 temporal_extent: ~ temporal_resolution: ~ type: dataset uri: /dataset/nasa-podaac-navo-l2p-avhrr17_g url: http://podaac.jpl.nasa.gov/dataset/NAVO-L2P-AVHRR17_G variables: ~ version: ~ vertical_extent: ~
