Standard daily pan evaporation is measured using the four-foot diameter 
Class A evaporation pan. The pan water level reading is adjusted when 
precipitation is measure to obtain the actual evaporation.  Most Class A
pans are installed aboveground, allowing effects such as radiation on the
side walls and heat exchnges with the pan material.  These effects tend to
increase the evaporation totals.  The amounts can then be adjusted by 
multiplying the totals b 0.70 or 0.80 to more closely estimate the evaporation
from naturally existing urfaces such as a shallow lake, wet soil or other 
moist natural surfaces.
    Many stations do not measure pan evaportation during winter months.  A "0.00"
total indicates no measuement is taken.

    Stations marked with an asterisk (*) have estimated totals computed from
meteorological measurements using a form of the Penman equation.
