Subject:
MAG/MWR/M1 -Incorrect retrievals
DataStreams:magmwrlosM1.b1
Description:
The PWV and LWP retrievals have higher uncertainty because of higher uncertainty in the 
calibration due to the ship movement and due to higher uncertainty in the retrieval 
coefficients.
Measurements:magmwrlosM1.b1:
  • Total water vapor along LOS path(vap)
  • Water, liquid, total along line-of-sight path, mean, 5-min avg(liq)

MAG/AOS/ALL/M1/S1/S2 - Ship in port
DataStreams:magmwrlosM1.b1
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)
