Precipitation (DP1.00006.001)

Primary precipitation will be measured by a weighing gauge surrounded by a small double fence inter-comparison reference (DFIR) at all core terrestrial sites. Secondary precipitation will be measured by a tipping bucket at all terrestrial relocatable sites, a select number of terrestrial core sites, and at aquatic sites. Throughfall will be measured by a tipping bucket equipped with troughs (extending outward from the tipping bucket) at all terrestrial sites where the canopy is seasonally taller than the height of the throughfall collectors' inlets. Instrumentation: Belfort AEPG II 600M weighing gauge (primary precipitation), Met One 372 tipping bucket (non-heated; secondary precipitation and throughfall) and 379 tipping bucket (heated; secondary precipitation)
