The Millimeter-wave Imaging Radiometer (MIR) was a passive airborne cross-track scanning radiometer developed by NASA. MIR measured brightness temperature across nine channels and was used for studying clouds, precipitation, and atmospheric water vapor. MIR operated near and around the following frequencies: 89, 150, 183, 220, and 325 GHz. It had an angular swath of 100 degrees and a sampling interval of 3 seconds. MIR usually operated on NASA ER-2 aircraft before being retired.
