Antarctic Research Center (AARC) on selective passes by satellite
receivers located at McMurdo Station, Antarctica (77 degrees, 51
minutes S, 166 degrees, 40 minutes E.) and Palmer Station, Antarctic
Peninsula (64 degrees, 46 minutes S, 64 degrees, 4 minutes W.)
Generally, most of the Antarctic continent and its coastline are
covered daily. Swaths are 2250 kilometers long and generally start or
end over the extreme South Pacific Ocean adjacent to the Ross Sea.
Data collection from Palmer Station covers the land areas of West
Antarctica, Southern South America, the South Atlantic including the
Falkland Islands and the South Orkney Islands, and the Drake Passage
and portions of the South Pacific Ocean. Continuous data collection at
the McMurdo Station began on 26 October 1987. Data are also archived
for 30 October 1985 - 2 December 1985 and for 30 October 1986 - 30
January 1987. Continuous data collection began at the Palmer Station 3
August 1989.
The data resolution is 1100 meters at subtrack, 4000 - 6000 meters at
limb; 360 scans per minute. Satellite revisit time is twice daily,
however, due to the proximity to the South Pole, 14 passes a day are
received at McMurdo and 10 passes a day are received at Palmer from
each spacecraft.
Data are acquired, archived, processed for requesters, and distributed
by the Arctic & Antarctic Research Center (AARC). Processing of the
raw data will depend on the requirements of the requester, but a
typical sequence might be as follows:
+ Reformat raw data for extraction; up to 10 missing scan lines can be
interpolated by the software.
+ Calibrate the reformatted data to convert from brightness values to
temperature values.
+ Apply the moisture/atmospheric correction.
+ Register selected data to the user-specified grid.
+ Transfer to user-specified medium. Some examples are tape, diskette,
photographic product, or file format for electronic transfer.
About 95 percent of the presently archived data have been cataloged on
our online directory. Data dropouts, caused by transmission
interference due to solar flare activity, occur in some images; the
processing software can smooth the data if fewer than 10 scan lines
are missing. All archived images contain usable data.
Processed data are binary byte arrays of user-defined size. Full
spacecraft attitude correction and earth correction routines are
applied to the raw data to create the products. Orbital elements,
equator crossings, altitude and period of the spacecraft are generated
for the raw data using the AARC scientific workstation. Data products
can be gridded to a user-specified grid.
Data are also available in raw form (10 bits of information stored in
a 16 bit word) on 4mm DDS2 or DDS3 DAT cassettes or DLT7000 tapes.
Users would need access to an 4mm DAT or DLT7000 reader. An
alternative method to access the digital archive is to use the Sun
Workstations located at the AARC, Scripps Institution of Oceanography.
AARC personnel can be contacted for access information.C1214584927-SCIOPS1987-10-26T00:00:00.000Z/Arctic & Antarctic Research Center (AARC) AVHRR and HRPT Direct Readout Radiance Data from McMurdo and Palmer Stations, AntarcticaFE09004ANot providedSCIOPSSCRIPPS/CALSPACE/AARCSCRIPPS/CALSPACE/AARCCARTESIAN-90 -180 -50 180falsefalsefalsefalsefalsefalsefalsefalse0.65https://cmr.earthdata.nasa.gov/opensearch/collections.atom?uid=C2119689675-ESACMRechodev@echo.nasa.govCEOSFEDEOAVHRR Level-1B Local Area Coverage ImageryThis collection is composed of AVHRR L1B products (1.1 km) reprocessed from the NOAA POES and Metop AVHRR sensors data acquired at the University of Dundee and University of Bern ground stations and from the ESA and University of Bern data historical archive. The product format is the NOAA AVHRR Level 1B that combines the AVHRR data from the HRPT stream with ancillary information like Earth location and calibration data which can be applied by the user. Other appended parameters are time codes, quality indicators, solar and satellite angles and telemetry. Two data collections cover the Europe and the neighbouring regions in the period of 1 January 1981 to 31 December 2020 and the acquired data in the context of the 1-KM project in the ‘90s. During the early 1990’s various groups, including the International Geosphere-Biosphere Programme (IGBP), the Commission of the European Communities (CEC), the Moderate Resolution Imaging Spectrometer (MODIS) Science Team and ESA concluded that a global land 1-KM AVHRR data set would have been crucial to study and develop algorithms for several land products for the Earth Observing System. USGS, NOAA, ESA and other non-U.S. AVHRR receiving stations endorsed the initiative to collect a global land 1-km multi-temporal AVHRR data set over all land surfaces using NOAA's TIROS "afternoon" polar-orbiting satellite. On the 1st of April 1992, the project officially began up to the end of 1999 with the utilisation of 23 stations worldwide plus the NOAA local area coverage (LAC) on-board recorders. The global land 1-km AVHRR dataset is composed of 5 channels, raw AVHRR dataset at 1.1km resolution from the NOAA-11 and NOAA-14 satellites covering land surfaces, inland water and coastal areas.

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.C1220567099-USGS_LTA1972-08-11T00:00:00.000Z/CEOS Cal Val Test Site - Algeria 3 - Pseudo-Invariant Calibration Site (PICS)CEOS_CalVal_Test_Sites-Algeria3Not providedUSGS_LTADOI/USGS/EROSDOI/USGS/EROSNot ProvidedCARTESIAN29.09 5.22 31.36 10.01falsefalsefalsefalsefalsefalsefalsefalse0.65org.ceos.wgiss.cwic.granules.prodorg.ceos.wgiss.cwic.granules.provider"USGSLSI"org.ceos.wgiss.cwic.granules.native_id"CALVAL_PIS_ALGERIA_3"gov.nasa.eosdisorg.geoss.geoss_data-coretruetruehttps://cmr.earthdata.nasa.gov/opensearch/collections.atom?uid=C1220567104-USGS_LTACMRechodev@echo.nasa.govCEOSCWICCEOS Cal Val Test Site - Algeria 5 - Pseudo-Invariant Calibration Site (PICS)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:
