MAG/AOSMET/M1 - Settings for wind measurements
DataStreams:magaosmetM1.a1
Description:
Settings for the WXT520 Weather Transmitter were changed may not be as users might expect. 

  
The wind speed and direction was read and recorded every second, but the averaging time 
was 3 seconds. This means that the wind reported each second was a running average of the 
last 3 seconds, not the second of the time stamp.
  
The wind speed was calculated as Gust & lull, instead of traditional Max/Min values.
Measurements:magaosmetM1.a1:
  • Wind direction, relative to true North(WindDirection)
  • Wind speed(WindSpeed)

Subject:
MAG/AOS/ALL/M1/S1/S2 - Ship in port
DataStreams:magaosmetM1.a1
Description:
The ship was in port during these periods and the measurements may be affected by various 
sources (overhead cranes, anthropogenic sources, etc).

Note: Dates and times were found by looking at the NAV datastream.  The standard deviation 
of pitch, roll, and surge velocity were used to determine when the ship was slowing down 
to enter port or speeding up to leave port.  Thresholds used; pitch (0.01), roll (0.01), 
surge velocity (3.0)
Measurements:magaosmetM1.a1:
  • ref_volts
  • Ambient air temperature(T_Ambient)
  • Ambient pressure(P_Ambient)
  • Rain amount(rain_amount)
  • base_time
  • Rain Duration(rain_duration)
  • Altitude above mean sea level(alt)
  • heater_volts
  • supply_volts
  • Wind direction, relative to true North(WindDirection)
  • Wind speed(WindSpeed)
  • time
  • time_offset
  • Ambient air relative humidity(RH_Ambient)
  • Rain intensity(rain_intensity)
  • heater_temp
  • North latitude(lat)
  • East longitude(lon)
