Comparison of National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) observations and those from National Data Buoy Center (NDBC) Buoy Station 46050 near the North Energy Test Site (NETS) offshore of Newport, Oregon.

Comparison of National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) observations and those from National Data Buoy Center (NDBC) Buoy Station 46050 near the North Energy Test Site (NETS) offshore of Newport, Oregon.

Sandia is cataloging wind, surface current, and wave data at US test sites to provide detailed and consistent wave-resource data that wave-energy developers can use to evaluate and compare different test sites. As part of this effort, Sandia compared National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) simulations for wind speed and direction with historic observations of these parameters from buoys at the North Energy Test Site (NETS) offshore of Newport, Oregon.

Monthly averaged values of wind speed and direction were found to agree well with values obtained from a decade and a half of meteorological observations from the National Data Buoy Center (NDBC) Buoy Station 46050. This comparison suggests that CFSR simulated data may be used in place of buoy data for improved assessment of wind conditions at US test sites; CFSR data generally has better spatial coverage than buoy data as well as longer periods of record, allowing assessment of wind characteristics closer to the test site with more accurate wind statistics.
