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:

| 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 |
