METHODOLOGICAL INFORMATION

The following are key notes on precipitation measurements at McMurdo Station
and included in these spreadsheet reports:

1.  For precip measurements, we have a snow gauge positioned in an open area
away from the town buildings.

2.  Precip is measured every 6 hours on the synoptic obs in town (00Z, 06Z,
12Z & 18Z).  Precip is not measured at the runways.

3.  The snow gauge is a standard measuring tool - a standard NWS D040-SP003 
system with a Nipher Shield.  After the precip is melted from the snow gauge, 
it is poured into a regular precip tube and measured with a stick.  (The 
measuring stick is marked in inches and millimeters and has a NOAA imprint 
near the top.)

4.  We obtain our snowfall amount by converting the liquid meltwater to a
snowfall equivalent based on the temperature. We use a standard chart (Table
12.2 in the AFMAN 15-11) for this.

5.  We do not measure snow on the ground (i.e. snow depth) at McMurdo due to
the high degree of drifting caused by the winds.
