DESCRIPTION: The Rainfall Accumulation products
attempt to estimate the amount of rainfall that has fallen
in a given area under the radar's umbrella. NEXRAD does this
by making certain assumptions about the number and kind of
raindrops it detects. There are certain limitations involved
with radar estimation of rainfall, which is a subject of
current meteorological research, and there are plans to
improve the way that NEXRAD produces its rainfall estimates.
A given rainfall product should generally be compared with a
product from another radar or with rain gage reports, if
they're available.
