Standard meteorological data. ATMP Air temperature (Celsius). For sensor heights on buoys, see Hull Descriptions. For sensor heights at C-MAN stations, see C-MAN Sensor Locations WTMP Sea surface temperature (Celsius). For sensor depth, see Hull Description. DEWP Dewpoint temperature taken at the same height as the air temperature measurement. BAR Sea level pressure (hPa). For C-MAN sites and Great Lakes buoys, the recorded pressure is reduced to sea level using the method described in NWS Technical Procedures Bulletin 291 (11/14/80). WSPD Hourly average wind speed (m/s) over an eight-minute period for buoys and a two-minute period for land stations. See Wind Averaging Methods. WD Hourly average wind direction (degrees clockwise from N) during the same period used for WSPD. See Wind Averaging Methods GST Peak 5 or 8 second gust speed (m/s) measured during the eight-minute or two-minute period. The 5 or 8 second period can be determined by payload, See the Sensor Reporting, Sampling, and Accuracy section. WVHT Significant wave height (meters) is calculated as the highest one-third of all of the wave heights during the 20-minute sampling period. See the Wave Measurements section. APD Average wave period (sec.) of all waves during the 20-minute period. See the Wave Measurements section. DPD Dominant wave period (seconds) is the period with the maximum wave energy. See the Wave Measurements section. MWD Mean wave direction corresponding to energy of the dominant period (DOMPD). See the Wave Measurements section.
