Longitude, Latitude, and Altitude can be
determined with a GPS Receiver, a Good
Topographical Map, or found at:
http://weather.noaa.gov/weather/ccus.html
(Figure
7).
The latitude and longitude must be entered as
decimal numbers. To convert the values to
decimal, ignore the seconds, divide the minutes by
60, then add that value to the degrees.
Example:
Latitude in Figure 6 is 41 degrees, 46 minutes,
58
seconds.
Decimal value = 41 + (46/60) = 41.78

Current—
the current barometric pressure (in Hg)
obtained from a Radio or Television Weather
Program or from the Web site:

(Figure 7).
VWS
—the barometric pressure (in Hg) found in
the Virtual Weather Station Software on the
Broadcast Display screen (Figure 8).
Zero, negative numbers, and very small
numbers are possible and acceptable as the
Barometric Pressure Offset.
