  Special Sensor Microwave/Imager - Wikipedia, the free encyclopedia
Information within the SSM/I TBs measurements allow the retrieval of four important geophysical parameters over the ocean: near-surface wind speed (note scalar not vector), total columnar water vapor, total columnar cloud liquid water and precipitation.
The SMMR was flown on Seasat and NASA Nimbus 7 in 1978.
The SSM/I failed to ‘spin-up’ after launch, and consequently data were not available from this instrument.

The SSMI technology was initially developed to monitor surface temperature and wetness from microwave energy naturally emitted from the land surface.  The SSMI has the clear advantage of being able to observe, monitor and measure the surface under almost all sky conditions.
The SSMI maps clearly captured the pattern of dryness, yet it is important to numerically capture the relationship between the surface temperature and wetness anomalies with variations in yield.
SSMI technology would have clear advantages as a settlement index where long-dated time series of temperature and rainfall are unreliable or when grouped station data are subject to error or manipulation.

 Total Precipitable Water Over Ocean from SSMI
Precipitable water from SSM/I is expected to be a primary source of long term measurements of atmospheric moisture content throughout the 1990s.
The SSM/I sensor is directed 45 degrees to the rear of spacecraft travel, yielding an angle of incidence to Earth's surface of 53.1 degrees.
In the microwave region of the spectrum sensed by the SSM/I instrument (19 GHz to 85 Ghz), water vapor, liquid water droplets, and oxygen are the major atmospheric constituents responsible for absorption of radiation emitted by the combined Earth-atmosphere system.

 Tropical Cyclone SSMI - Wind Tutorial
The SSM/I wind speed parameter, which gives oceanic surface wind speed but not direction, has the most utility away from heavy clouds and precipitation.
The main utility of this parameter is outside most of the heavy clouds and precipitation and on the fringes of the storm where wind speeds can be successfully observed.
Thus, it is sometimes difficult to understand a wind speed image unless the forecaster also refers to surface wind charts or satellite pictures of the same region.

 The Baytown Sun   (Site not responding. Last check: 2007-11-02)
The ruling notes that this management agreement called for SSMI to “account to [the City] for all Complex expenses prior to payment by [the City] and that SSMI shall establish and maintain one or more accounts — for the disbursement of payroll and related Complex expenses.
“SSMI is therefore obligated under the terms of the Agreement to maintain records of the salaries disbursed to its employees in connection with its management and operation of the Complex.
The opinion does not address one of the primary questions of the appeal, whether SSMI is a government entity and therefore subject to the Texas Public Information Act.

 JPL Air Sea Interaction & Climate Team - Science
Satellite observations, in situ measurements, and model simulations are combined to assess the oceanic response to surface wind forcing in the equatorial Pacific.
When SSMI winds are used to force a primitive-equation ocean general circulation model (OGCM), they produce 3C more surface cooling than ECMWF winds for the eastern equatorial Pacific during the cool phase of an El Niño Southern Oscillation (ENSO) event, as shown in the middle figure.
The stronger cooling by SSMI winds is in good agreement with measurements at the moored buoys and observations by the Advanced Very High Resolution Radiometer (AVHRR).

 UPDATE   (Site not responding. Last check: 2007-11-02)
Comparison with independent cloud data from the SSMI instrument shows a good agreement with ISCCP low cloud amount until 1994, after which the two data sets appear to diverge.
The SSMI instrument operates at microwave wavelengths, which are able to penetrate ice and dust clouds, and thus observe liquid water clouds only.
However, the period starting January 1992 is independent of this preselection, and yet still shows a good agreement up until around June 1994 indicating that the two techniques to derive cloud amount are detecting the same relative cloud properties.

 Sisters Servants to celebrate centennial of their mission (09/29/02)
WINNIPEG - The Ukrainian Byzantine Rite Sisters Servants of Mary Immaculate (SSMI) in Canada will hold eparchial celebrations of the centenary of their mission on Sunday, October 6, with a divine liturgy of thanksgiving at St. Nicholas Ukrainian Catholic Church, to be followed by a luncheon at the Ramada Marlborough Hotel.
In 1902, in response to a request by the Canadian Roman Catholic hierarchy, Metropolitan Andrey Sheptytsky sent a group comprising three Basilian priests, a lay brother and four Sisters Servants of Mary Immaculate, to minister to the new Ukrainian immigrants in Canada.
The SSMI novitiate was transferred from Mundare, Alberta, to Ancaster, Ontario, in 1946 and their central headquarters to its present location in Toronto in 1949.

 NCDC: SSM/I Global Gridded Products
The SSM/I is a seven channel passive microwave radiometer operating at four frequencies (19,35, 22,235, 37.0, and 85.5 GHz) and dual-polarization (except at 22.235 GHz which is V-polarization only).
It should be noted that the SSM/I will be replaced by an advanced sensor, the SSMIS (Special Sensor Microwave Imager Sounder) on the F-16 satellite, which was launched in October 2003.
A paper by M. Colton and G. Poe entitled "Intersensor Calibration of DMSP SSM/I's: F-8 to F-14; 1987-97" appears in the January 1999 issue of IEEE Transactions on Geoscience and Remote Sensing and is a good reference on the SSM/I sensor.

Therefore you will need to read in this SSMI data using whatever format it is in and use the coordinates from the ARC file to crop out the correct area from the SSMI data.
I think that the dimensions of the ARC data and the cropped SSMI data should be the same.
This should probably be a modification of the existing SSMI read program as you want to retain the process that converts antenna temperatures to brightness temperatures.
