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 to study clouds, precipitation, and atmospheric water vapor. MIR operated near the following frequencies: 89, 150, 183, 220, and 325 GHz. It had a 100-degree angular swath and a sampling interval of 3 seconds. MIR usually operated on NASA ER-2 aircraft before being retired.
