A correlation radiometer that measures the shape and strength of a water vapor line giving a profile of water vapor as a function of altitude has been developed at MIRSL. Future work is aimed at extending the instrument's capability to three-dimensional profiling.
A stepped frequency microwave radiometer designed and built at MIRSL has flown on an NOAA hurricane reconnaisance aircraft for several years to provide wind speed data.

Will fly with MIRSL's L-band radiometer to obtain multiple frequency sensing of soil moisture.
