Abstract
One of the major achievements of the space age has been establishment of satellite systems which monitor precisely our global environment and our impact upon it. One key tool for advancing scientific and operational observations of the atmosphere has been passive microwave sensors which penetrate most non-precipitating clouds and map global temperature, humidity, and precipitation profiles with 15-50 km horizontal resolution. Such instruments with considerable MIT heritage currently have 20 channels spaced from 23 to 190 GHz.
Aircraft and future satellite experiments will be described together with the underlying technology and some of the mathematical techniques used to estimate atmospheric states in this non-linear, non-jointly-Gaussian, and non-stationary environment.
