    Description:

    AVHRR satellite imagery of Eastern Antarctica, captured by the NOAA12 satellite. Data have been collected since June of 1996, but not all locations have archives dating back to this time. Images are available of the following areas: Princess Ragnhild Coast (West) Princess Ragnhild Coast Princess Ragnhild Coast (East) Enderby Land Mawson region Davis - Prydz Bay West Ice Shelf Shackleton Ice Shelf Casey region Sabrina Coast Wilkes Coast Dumont d'Urville - Mertz Gl. Ninnis Glacier region Cape Adare Terra Nova Bay Ross Ice Shelf However, this AVHRR sea-ice archival service was discontinued in 2015. Please contact the Bureau of Meteorology's Regional Manager for Antarctic Meteorology at tasrmam@bom.gov.au for any satellite archive support.

  • Bi-Weekly and Monthly Mean SST Archive and Accumulation Files from the NOAA TIROS/N Satellite Series

    https://cmr.earthdata.nasa.gov/search/concepts/C1214419996-SCIOPS.xml
    Description:

    The Bi-Monthly SST Archive tape (SSTFLD) contains a half month archive of 1 X 1 degree satellite-derived SST fields between 70S and 70N. The tape is produced on the 2nd and the 16th of each month and contains daily fields for the previous 20 days. The tape is a 9-track, 1600 bpi, unlabeled, odd-parity, binary tape produced on an IBM 360/195 computer. The tape has two physical files, each ending with a physical end-of-file mark. The first file has only one record (physical) which contains information about the data on the tape and serves as a header file. The second file has 2851 physical records. The first record is a directory record pointing to each of twenty individual fields. Each field has 142 records. The Satellite Monthly Mean Archive tape (SSTMON) contains 12 monthly mean sea surface temperature (SST) fields for one calendar year. File two of the tape is a direct copy of the disk data set NSS.PSATAV.SST.MEANFLD. This archive is created on January 10th every year, archiving the monthly mean fields for the previous year. Data on this tape were derived exclusively from satellite data. The field has a 2.5 X 2.5 degree resolution. For each 2.5 degree box in the field there is a count of the number of observations in the box, the mean, and the standard deviation. The tape is a 9-track, 1600 bpi, unlabeled, odd-parity, binary type produced on an IBM 360/195 computer. The tape has two physical files, each ending with a physical end-of-file mark. The first file has only one record (physical) which contains information about the data on the tape and serves as a header file. The second file has 72 physical records, each containing 12 logical records, containing satellite SST monthly mean data. The Monthly Mean SST Accumulation file (MOMEAN) provides storage for a global 2.5 degree resolution accumulation of SST information leading to a monthly determination of mean SST and standard deviation within each grid box. Boxes are bordered by meridians and parallels which are multiples of 2.5 degrees in latitude and longitude, so that 4 boxes may be combined to produce boxes centered on intersections of meridians and parallels which are multiples of 5 degrees in latitude and longitude. Three quantities are stored for each grid box and are operated twice weekly with newly arrived observations. These are 1) the number of observations occurring in the box, 2) the sum of the measured temperatures, and 3) the sum of these temperatures. From these, a mean temperature and standard deviation are derived for each box at the end of each month. There are 144 X 72 = 10,368 boxes covering the globe. Each requires 3 words--N, T, T2-- or 12 bytes of storage. Seven latitudinal rows of 144 boxes will fit on one track so that 10 2/7 tracks are required each month. Four months' data will be maintained on disk so that a quarterly report can be comprised from the file directly. The fourth month makes provision for lags in processing. One directory record will be needed, and 42 tracks are required in all.

  • BOREAS Level-3b AVHRR-LAC Imagery: Scaled At-Sensor Radiance in LGSOWG Format

    https://cmr.earthdata.nasa.gov/search/concepts/C179003254-ORNL_DAAC.xml
    Description:

    Data acquired from the AVHRR instrument on the NOAA-9, -11, -12, and -14 satellites were processed and archived. A few winter acquisitions are available, but the archive contains primarily growing season imagery. These gridded, at-sensor radiance image data cover the period of 30-Jan-1994 to 18-Sep-1996. Geographically, the data cover the entire 1000 km x 1000 km BOREAS Region.

  • CEOS Cal Val Test Site - Algeria 3 - Pseudo-Invariant Calibration Site (PICS)

    https://cmr.earthdata.nasa.gov/search/concepts/C1220567099-USGS_LTA.xml
    Description:

    On the background of these requirements for sensor calibration, intercalibration and product validation, the subgroup on Calibration and Validation of the Committee on Earth Observing System (CEOS) formulated the following recommendation during the plenary session held in China at the end of 2004, with the goal of setting-up and operating an internet based system to provide sensor data, protocols and guidelines for these purposes: Background: Reference Datasets are required to support the understanding of climate change and quality assure operational services by Earth Observing satellites. The data from different sensors and the resulting synergistic data products require a high level of accuracy that can only be obtained through continuous traceable calibration and validation activities. Requirement: Initiate an activity to document a reference methodology to predict Top of Atmosphere (TOA) radiance for which currently flying and planned wide swath sensors can be intercompared, i.e. define a standard for traceability. Also create and maintain a fully accessible web page containing, on an instrument basis, links to all instrument characteristics needed for intercomparisons as specified above, ideally in a common format. In addition, create and maintain a database (e.g. SADE) of instrument data for specific vicarious calibration sites, including site characteristics, in a common format. Each agency is responsible for providing data for their instruments in this common format. Recommendation : The required activities described above should be supported for an implementation period of two years and a maintenance period over two subsequent years. The CEOS should encourage a member agency to accept the lead role in supporting this activity. CEOS should request all member agencies to support this activity by providing appropriate information and data in a timely manner. Pseudo-Invariant Calibration Sites (PICS): Algeria 3 is one of six CEOS reference Pseudo-Invariant Calibration Sites (PICS) that are CEOS Reference Test Sites. Besides the nominally good site characteristics (temporal stability, uniformity, homogeneity, etc.), these six PICS were selected by also taking into account their heritage and the large number of datasets from multiple instruments that already existed in the EO archives and the long history of characterization performed over these sites. The PICS have high reflectance and are usually made up of sand dunes with climatologically low aerosol loading and practically no vegetation. Consequently, these PICS can be used to evaluate the long-term stability of instrument and facilitate inter-comparison of multiple instruments.
