YYYY/MM/DD HH:MM SS.SSSS SS.SSSS DDD.D AAA.A BBBB.BB DDMM.MMMM DDDMM.MMMM AAAA.A N SS PPP.P HHH.H DD.DD VV.VV PPP.P RRR.R

where YYYY/MM/DD = Date year/month/day
      HH:MM      = Time hour/minute
      SS.SSSS    = Wind speed, scalar average, m/s
      SS.SSSS    = Wind max speed, m/s
      DDD.D      = Wind direction, vector average, degrees
      AAA.A      = Air temperature average, C
      BBBB.BB    = Barometric pressure average corrected to sea level, mbar
      DDMM.MMMM  = Latitude North, degrees/minutes
      DDDMM.MMMM = Longitude West, degrees/minutes
      AAAA.A     = Altitude, m
      N          = GPS quality: 0=invalid, 1=normal, 2=differential
      SS         = Number of satellites used
      PPP.P      = Horizontal dilution of precision (HDOP), m
      HHH.H      = Magnetic heading, vector average, degrees
      DD.DD      = Magnetic deviation average (E/W), degrees - from internal compensation
      VV.VV      = Magnetic variation average (E/W), degrees - earth variation from true north
      PPP.P      = Pitch average, degrees
      RRR.R      = Roll average, degrees

      Invalid values are all 9's

All times are UTC
Wind sensors & air temperature sensor are 2.3 m above water surface
Sensors are measured once every 5 seconds
Sensors are averaged over a 2 minute interval
