Variables for R/V Knorr experiment :
    February/March 1997

     date = year-month-day
     hour = decimal hour
     lat = latitude North ( - = South )
     lon = longitude East ( - = West )
     ws = wind speed at 10 meters
     ssT = sea near-surface temperature 
     airT = air temperature
     qa = specific humidity
     CD10N*1000 = drag coefficient * 1000.0  ( derived from dissipation method )
     shf1 = sensible heat flux ( from dissipation method )
     shf2 = sensible heat flux ( from cross correlation method )
     shf3 = sensible heat flux ( from Isemer and Hasse '87  method )
     shf4 = sensible heat flux ( from Large and Pond '82  method )
     shf5 = sensible heat flux ( from DeCosmo et al. '96  method )


  Measurements by IfM Kiel, air temp., spec.hum. and SST from the ship's
  IMET. Turbulence measurements were performed using a 'Metek USA 1'
  sonic anemometer. The date gives the beginning of time series of a
  length of approximately 17 minutes used to derive heat fluxes
  ( dissipation and cross correlation method ) and drag coefficients
  ( dissipation method). Bulk estimates are based on data from the 
  ship's IMET.
