Variables for 7JWN ( Takuyo WOCE ) experiments :

     date = year-month-day
     hour = decimal hour
     lat = latitude North ( - = South )
     lon = longitude East ( - = West )
     ws = wind speed ( earth relative  at 19 m )
     seaT = sea near-surface temperature ( 5 m depth )
     airT = air temperature ( 10 m )
     qa = specific humidity ( calculated from rhum )
     wdir = wind direction from North ( 19 m )
     pres = atmospheric pressure ( 10 m )
     rhum = relative humidity ( from 7JWN dry and wet bulb temp. )
     cloud = total cloud amount index
