DMSP F8 Special Sensor Microwave/Imager (SSM/I) Brightness Temperature 
Grids for the Polar Regions (Price on request):
  18 CD-ROM discs contain daily gridded brightness temperature (Tb) for 
the north and south polar regions (areas where sea ice occurs), on polar stereographic grids, 9 July 1987 through 31 December 1991.  Each CD-ROM contains approximately 3 months of data.  Defense Meteorological Satellite Program (DMSP) F8 platform carried this first functional SSM/I instrument.  
The SSM/I is a 7-channel, 4-frequency, linearly polarized, passive
microwave radiometric system; channels are 85.5 GHz Vertical/Horizontal, 37.0 GHz Vertical/Horizontal, 22.2 GHz Vertical, 19.3 GHz Vertical/Horizontal.
  Fortran program provided on diskette to extract single channel from 
inter-leaved storage format.  Images can be displayed using IDL or other Unix or PC software.  For 1992 and later data, see DMSP F11 SSM/I Brightness Temperature Grids for the Polar Regions, below.

DMSP F8 Special Sensor Microwave/Imager (SSM/I) Sea Ice Concentration Grids for the Polar Regions 1987 - 1991. (Price on request):
  DMSP F8 SSM/I Ice Concentration Grids for the Polar Regions consist of daily first-year, multi-year, and total ice concentration on 25 x 25 km polar stereographic grids for north and south polar regions.  SSM/I sea ice CD-ROMs contain two sets of grids, 1) NASA Team algorithm; 2) J.C. Comiso algorithm. Orbital antenna temperatures are processed to gridded brightness temperatures and then used to derive gridded ice concentrations.  The SSM/I sensor flies on U.S. Air Force Defense Meteorological Satellite 

Program (DMSP) platforms; the first operational SSM/I (Special Sensor Microwave/Imager) was that on DMSP F8.  Two CD-ROMs contain all F8 SSM/I ice concentrations, 9 July 1987 - 31 December 1991.  North polar files are 137202 bytes, south polar are 105922 bytes.  
  Data are in HDF format and can be read using software from the National Center for Supercomputing Applications (NSCA), available by anonymous ftp from NCSA (ftp.ncsa.uiuc.edu) or with commercial packages such as IDL.  
  The SSM/I is a 7-channel, 4-frequency, linearly polarized, passive microwave radiometric system: 85.5 GHz Vertical/Horizontal, 37.0 GHz Vertical/Horizontal, 22.2 GHz Vertical, 19.3 GHz Vertical/Horizontal.  DMSP F11 SSM/I ice concentrations for 1992 and later dates will be produced starting in late 1994, after the ice algorithms have been modified for F11 data.
  Contact NSIDC, information above.

DMSP F11 Special Sensor Microwave/Imager (SSM/I) Brightness Temperature Grids for the Polar Regions.  (Price on request):
  CD-ROM discs contain daily gridded brightness temperature (Tb) for the north and south polar regions (areas where sea ice occurs), on polar stereographic grids, beginning on 3 December 1991.  Each CD-ROM contains approximately 3 months of data in single-channel files, in HDF (Hierarchical Data Format).  As of 8/94, 5 volumes cover 12/91 - 2/93.  Inquire for latest available data. 
  Software to read and manipulate the data in HDF is available via ftp from National Center for Supercomputing Applications (NCSA): ftp to 
ftp.ncsa.uiuc.edu; help is available from NCSA at helphdf@ncsa.uiuc.edu.  
Data can also be displayed and manipulated using commercial packages such as IDL.  
  The Defense Meteorological Satellite Program (DMSP) F11 platform carries this SSM/I instrument, a 7-channel, 4-frequency, linearly polarized, passive microwave radiometric system; channels are 85.5 GHz Vertical/Horizontal, 37.0 GHz Vertical/Horizontal, 22.2 GHz Vertical, 19.3 GHz Vertical/Horizontal.
This product uses the same grid and projection as the NSIDC DMSP F8 SSM/I brightness temperature and sea ice concentration CD-ROMs (1987 - 1991, see above).

Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) Polar Radiances and Arctic and Antarctic Sea Ice Concentrations, 1978 - 1987.  (Price on request):
  Scanning Multichannel Microwave Radiometer (SMMR) Polar Radiances and 
Sea Ice Concentrations on CD-ROM contain gridded brightness temperatures (Tb) and sea ice concentrations for 10/78 - 8/87 (the life of the Nimbus-7 SMMR scanner) for both polar regions on 12 CD-ROMs.  Data were collected at 6.60, 10.69, 18.00, 21.00 and 37.00 GHz in an alternate-day operating pattern due to spacecraft power limitations.  [NOTE: Input data set is SMMR TCT tapes; this is different from the previous SMMR CD-ROM product distributed by NSIDC in 1989.]  Tb (in Kelvins) and sea ice concentration 

(in percent) grids have 25 x 25 km grid elements in polar stereographic projection.  
Volume 7 contains all SMMR sea ice concentrations for both polar regions, plus 5 months of Tb grids for the north polar region.  The Tb grids are stored as 16-bit integers; one day of Tb data is 0.27 mbytes for the north polar region, 0.21 mbytes for the south.  Ice grids are stored as 8-bit integers, each file = 136192 bytes for the north, 104912 bytes for the south.
The NASA Team Algorithm (Cavalieri et al., 1984; Gloersen and Cavalieri, 1986) was used to calculate ice concentrations from the Tbs.  Data produced by Dr. P. Gloersen, NASA/GSFC, Oceans and Ice Branch.  
  Documentation is provided on the CD-ROMs, in a hard-copy User's Guide, and in the "SMMR Atlas", NASA Special Report SP-511 (Gloersen, et al., 1992.)

SAM II Aerosol Data (no cost):
  Contains Stratospheric Aerosol Measurement (SAM) II data collected from October 1978 - January 1993, documentation, and read software.   The SAM II instrument, aboard the Earth-orbiting Nimbus-7 spacecraft, was designed to measure solar irradiance attenuated by aerosol particles in the Arctic and Antarctic stratosphere.  The scientific objective of the SAM II experiment was to develop a stratospheric aerosol database for the polar regions by measuring and mapping vertical profiles of the atmospheric exti

nction due to aerosols.  This database allows for studies of aerosol changes due to seasonal and short-term meteorological variations, atmospheric chemistry, 
cloud microphysics, and volcanic activity and other perturbations.
