Development of a Marine Profiling Radiometer

This Phase I project proposes the development of a Marine Profiling Radiometer (MPR). The MPR is a passive microwave remote sensor capable to measure the stability of the marine boundary layer. Significant innovations in radiometer design, packaging, mode of operation, and calibration enable the MPR to operate in the unforgiving marine environment for an extended time without maintenance and user intervention. The buoy installed radiometer will provide thermodynamic profiles of the whole atmospheric column above the MPR. Temperature and water vapor profiles, integrated cloud liquid content and integrated water vapor are very important data inputs into rapid refresh weather models. Improved mesoscale weather forecasts have the potential to significantly improve the economy of the offshore wind resources. These forecasts can enable as well a better total production prediction and onshore electric grid load anticipation. In addition, a reliable forecast will prevent potential damages to the turbines, e.g., from excessive wind or freezing drizzle. As a part of the complementary infrastructure of the offshore wind industry, the data from the MPR will improve offshore and near shore forecasts thus enabling better wind resource integration into existing power grids. This will also allow better scheduling of maintenance or other work necessary to realize the potential of the offshore wind industry in the United States and abroad.
