The report is focused on radio-frequency interference (RFI) to radiometric measurements made by Earth exploration-satellites. The natural noise floor in the bands under consideration is the data being measured. The text first discusses how the measurements are used in meteorological and climatic products. Then, it addresses the detectability of RFI and its potential impact on products. Finally, it discusses some techniques that might be used to mitigate (reduce, not eliminate) the impact from RFI. No mitigation techniques have been identified which can be applied to the microwave sensors and their products to allow RFI without degrading their performance reliability or availability.
