2. DATA SOURCES 



The primary sources of data for all cases considered were the Final 

 Meteorological Radiation (FMR) magnetic tapes prepared by NASA. Listings of 

 the available data tapes and descriptions of the data contained therein have been 

 published. Extraction of the actual data from the FMR tapes is accomplished by 

 processing programs developed by NASA for use on the IBM 7094. 



The processing can make the data available in any of several formats. The 

 listing program (MS -500) converts the binary FMR data to decimal form and 

 prints it in a convenient tabular format. This tabulation includes data point 

 location information, and values measured by each of the five channels of the TIROS 

 radiometers. Mapping programs are available which map the data to various 

 scales in either a mercator projection (MSC-2) or a polar stereographic projection 

 (MS-501).
