Monthly graduated rain gauge (GRG) precipitation at 15 NPP sites (LTER-II)

A 4" diameter cylindric graduated rain gage (11" x 0.01" capacity)
is mounted on a 4x4 inch diameter redwood post or on a wooden
exclosure post next to gate at or near the 15 LTER-II NPP sites.
Collection is made monthly on the day that monthly soil water
content measurements are made to correlate precipitation input
with belowground water content.

Data is collected primarily from graduated rain gauges. However,
when missing data would result otherwise, amounts from the closest
rain gauge are used in order to maintain as complete a data set as
possible for that site. The rain gauge used is identified with
each rainfall record. Other types that may be used are the Standard
Can Gauge (DSRG or dipstick rain gauge), Belfort Weigh Bucket Rain
Gauge (WBRG), and Qualimetrics Tipping Bucket Rain Gauge (TBRG).
