Locational Information gives the latitude, longitude, and elevation for each city, plus information about temperatures and precipitation.
The Daily Mean Maximum Temperature
and Daily Mean Minimum Temperature
graphs each contain three plots. The black
lines show the average (mean) high or low
temperature for each date. The red lines
show the highest recorded temperatures for
each day of the year and the blue lines
show lowest recorded temperatures.
On the Daily Mean Precipitation and Snowfall
graph, the blue line indicates the average
daily amount of precipitation (rain and
snow combined), in hundredths of an inch.
The red line shows the average amount of
snowfall, in tenths of an inch. Melting
1 inch of snow produces about 0.1 inch of
water, so the precipitation and snowfall
plots are usually very nearly the same height.
