# # ATLAS data header # For ATLAS deployed on M2 mooring # Deployment date 28 February 1995 # # ATLAS data records in this file contain 25 floating-point values, as follows: # # oasis_time atlas_time air sst t10 t20 t40 t60 t80 t100 t150 t200 t300 t500 p200 p500 humidity windspeed winddir windu windv compass vane rawdir rawspeed # # oasis_time: GMT time that oasis collected data from ATLAS. 1 sec precision. # Format is ddd.fffff where ddd is julian day, fffff is fraction of day. # atlas_time: GMT time that ATLAS collected data. 15 minute precision. # Same format as oasis_time # air: Air temperature in degrees Celsius # sst: Sea surface temperature in degrees Celsius # t10 - t300: Temperature in degrees Celsius at depth [10 - 300] meters # p200 - p300: Pressure in decibars at 200 or 300 meters # humidity: Relative humidity in percent # windspeed: Wind speed in meters/second # winddir: Direction wind is blowing towards, compass degrees from true north # windu: Wind u (e-w) vector in meters/sec, calibrated & w/ magnetic correction # windv: Wind v (n-s) vector in meters/sec, calibrated & w/ magnetic correction # compass: Raw compass reading in degrees, single sample (i.e. not averaged) # vane: Raw vane position in degrees, single sample # rawdir: Raw wind direction, derived from compass and vane, single sample # rawspeed: Raw wind speed in meters/second, single sample #
