Abstract
The Compact Midwave Infrared System (CMIS) is a multi-angle, multi-spectral radiometer designed for high-spatial resolution stereo imaging in the shortwave infrared (SWIR)/midwave infrared (MWIR). The unique design of CMIS enables the capability to track diverse targets ranging from hot wildfires to cold clouds. CMIS is a low-size, -weight and -power (SWaP) instrument that can be accommodated on a small-satellite constellation to enable a rapid revisit rate needed for characterizing dynamic scenes. CMIS employs mature stereographic techniques to retrieve object heights and motion vectors that are free of the ambiguities between height assignment and along-track motions that are apparent in some earth-observing missions. This capability can be applied to cloud motions to derive accurate 3D winds related to the development and maintenance of atmospheric rivers, for example. An airborne test campaign of four NASA Gulfstream III flights successfully demonstrated CMIS capabilities. This presentation will describe the results of those flights, including a limited comparison against the ADM Aeolus lidar, and define a concept of operations for quantifying both horizontal and vertical motions.
