The SASP precip
gauge (ETI Instruments™ Noah II), shown here in late fall, is a fully
automated, transducer-type gauge with a reservoir of alcohol fluid and a standpipe
for waste storage. No fluids are released on site. The single 40 watt photovoltaic
panel seen in the photograph charges a 400 amp-hour battery bank contained
in the enclosure located on the ground next to the precip gauge. Precipitation
storm totals are monitored using a manually measured 'storm board' at the
site, to corroborate the precipitation gauge measurements.
