Arctic & Antarctic Research Center (AARC) AVHRR and HRPT Direct Readout Radiance Data from McMurdo and Palmer Stations, Antarctica
https://cmr.earthdata.nasa.gov/search/concepts/C1214584927-SCIOPS.xml
AVHRR HRPT level 0 raw telemetry data are acquired at the Arctic and 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.

AVHRR data from Eurimage
The National Oceanographic and Atmospheric Administration (NOAA) has been operating its Advanced Tiros-N (ATN) series of satellites since October 1978. Carrying the Tiros Operational Vertical Sounder (TOVS), a low-data-rate atmospheric sounding package, and the Advanced Very-High Resolution Radiometer (AVHRR), these satellites were designed primarily for meteorological applications, but the AVHRR instrument, in particular, has proved very valuable in a variety of environment linked earth observation applications, such as: drought early warning regional and global vegetation monitoring snow and ice mapping dynamic oceanography hydrology geology detection of forest fires, gas flares and agricultural burning fire fuel mapping volcanology air and sea pollution monitoring toxic algal bloom detection continental scale mapping (less than 1:3,000,000). Eurimage distributes AVHRR data from NOAA, acquired from the TIROS satellites and received mainly at ESA ground stations. Coverage of Europe, Africa, the Middle East and parts of the Far East is provided, as shown in the sketch map below. With at least two satellites operational at any one time, each with a daily repeat cycle, twice daily and twice nightly coverage is possible for any point on the equator and approximately double this number (8 passes in total) at mid-latitudes.

NOAA maintain at least two operational satellites in complementary orbits, with one crossing the equator at local solar times of approximately 0730 and 1930, and the other at 0230 and 1430. By convention, the even-numbered satellites cover the 'morning orbit' (0730) and the odd-numbered satellites the 'afternoon orbit' (1430). The Advanced Very High Resolution Radiometer is a four (AVHRR/1) or five (AVHRR/2) channel passive scanning radiometer. It has one visible channel, one near-infrared, one middle-infrared, and one/two far-infrared channels. The nominal ground resolution is about 1 km. The extra channel of the AVHRR/2 (Channel 5) affords improved atmospheric correction of sea and land surface temperatures.

AVHRR Leads-ARI Polar Gridded Brightness Temperatures, Version 1
https://cmr.earthdata.nasa.gov/search/concepts/C1386246913-NSIDCV0.xml
This data set consists of AVHRR imagery selected from hard copy 'quick look' images to provide the best coverage possible over the Arctic approximately every three days for a three-year period. Level-1B data from NOAA/SDSD have been calibrated and mapped to earth locations, then gridded to 1 km pixels on a basin scale to the polar stereographic projection. The projection is similar to that used by NSIDC to produce DMSP SSM/I polar brightness temperature and sea ice products. Each image was ranked for areal coverage of particular seas and for degree of cloud coverage. Passes covering a large area are generally favored over shorter passes with less cloud cover. The data set was developed in support of the Office Of Naval Research Arctic Leads Accelerated Research Initiative (Arctic Leads ARI). The aim of the Initiative was to develop a more thorough understanding of the oceanography, meteorology, and ice dynamics surrounding formation and evolution of leads in sea ice. The leads ARI field experiment took place from March to April 1992. A spreadsheet containing the image rankings is available in hard copy (NOARL Tech. Note 118, April 1991); paper copies of the spreadsheet are available on request. Data set information is available on-line. Data are available via FTP.

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

CEOS Cal Val Test Site - Algeria 3 - Pseudo-Invariant Calibration Site (PICS)
https://cmr.earthdata.nasa.gov/search/concepts/C1220567099-USGS_LTA.xml
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.
