Abstract: The Center for Ocean-Atmosphere Prediction Studies (COAPS [http://www.coaps.fsu.edu]) through their Research Vessel Surface Meteorology Data Center (RVSMDC ) collect, quality control check, and archive high-resolution marine surface data taken aboard ocean research vessels. The measurements are made with modern and calibrated instrument ... packages with sampling on the order of one-minute frequency. This is a long-term archive for these data. These data and near real-time extensions can be obtained directly from the RVSMDC. To support the International Comprehensive Ocean-Atmosphere Data Set (ICOADS [http://icoads.noaa.gov/]) a representative hourly archive is derived from the high-resolution data. These data are available here as archive files and conveniently through ICOADS user data selection interface  as 'ICOADS Auxiliary Data Selection'.
