NCAR's MCR
(Multichannel Cloud Radiometer)

Calibration of the MCR at the Los Alamos National Lab
 
 

The MCR is a seven-channel radiometer that scans between ±45° about the NSF/NCAR C-130 track.  The current specifications and research applications of the MCR are summarized below:

  

Channel #
Central Wavelength (µm)
Bandwidth (FWHM - µm)
Application
1
0.640
0.063
Cloud, aerosol, sfc mapping
2 0.470 0.040 sea ice, land, water color
3 0.870 0.040 vegetation health
4 1.06 0.07 water vapor, sfc mapping
5 1.64 0.05 snow-ice diff, cloud phase
6 2.16 0.08 cloud phase, particle size, land sfc properties
7 10.9 0.9 thermal mapping

Other MCR specs:

Field of view: 0.007 radians
Mirror scan rate: 3.47 revolutions/sec
# pixels: 360 per active scan (±45°)
Swath: twice the aircraft height above target
Data sampling rate: 5000 samples/sec, each channel simultaneously
