The goal of the IMPOWR (Improving the Mapping and Prediction of Offshore Wind Resources) project (funded by DOE) is to improve mesoscale modeling of low-level wind fields through a combination of unique observations of the boundary layer and next-generation ensemble modeling. If successful, this would improve meteorological forecasts over the ocean, which would benefit navigation as well as offshore wind operations and day-ahead power sales. The observational campaign includes a multiyear set of meteorological and oceanographic observations at the Cape Wind meteorological tower as well as a 15-20 Long-EZ aircraft flights by UltraPure Air, LLC. The intention of this portion of the project is to measure a complete meteorological profile (wind speed, temperature and humidity) from the ocean surface to the top of the atmospheric boundary layer in addition to some turbulence and flux measurements. This work plan describes the installation of instruments on the Cape Wind meteorological tower (Cape Wind’s Licensed Property) as part of this unique data campaign.

For the IMPOWR project, SUNY Stony Brook is responsible for the modeling and data assimilation portion of the project, as well as the aircraft portion of the field campaign. The University of Delaware is responsible for the meteorological tower portion of the field campaign including preparation of the instrument suite and data logger, processing of the field campaign data, and processing of other meteorological data in the study area. The IMPOWR team of investigators intends to install a suite of new, state-of-the-art, high-accuracy, and high-frequency meteorological and oceanographic instruments on the Cape Wind meteorological tower in the summer of 2012. The suite of instruments provided by the IMPOWR team includes 4 sonic anemometers, 3 temperature and 1 relative humidity sensors, and an optical wave gauge.
