 (IRLS) OS applied to oceanography 



1. HRIR (High Resolution Infrared Radiometer): Designed to 

 measure thermal radiation from the earth in the 3-^ to 

 U.2 micron range. Provide day and night iiiHgery and 

 blackbody temperature equivalents at night. 



2. MRIR (Medium Resolution Infrared Radiometer) : Designed 



to measure the terrestrial, atmospheric and solar radiation 

 of the earth in five wavelength bands between 0.2 and 

 23 microns. The channel and wavelengths are: (1) 6.7. 

 (2) 10.0 to 11.0, (3) 1^.5 to 15.5, {k) 20.0 to 23.0, 

 (5) 0.2 to k.O. 



3. IOCS (image Dissector Camera System): Designed to 

 provide daytime television pictures of the earth to be 

 transmitted in real time or be stored for data playback 

 at CDA stations. 



k. IRLS (interrogation, Recording and Location System): Designed 

 to locate ground stations and, when required, interrogate 

 and record data accumulated at selected ground stations. 

 On passing over Ground Acquisition and Control Station, 

 the data is read out and a new command sequence for the 

 next orbit started.
