Long-Term Ecological Research (LTER)/AND018: NADP Precipitation Chemistry in the H.J. Andrews Forest

LTER - Long-Term Ecological Research Program/H.J. Andrews Forest (AND)

LTER/AND018 [Summary adapted from the LTER Core Data Set Catalog]:

The National Atmospheric Deposition Program (NADP) wet/dry sampler is
located in a cleared area at the Andrews Forest Headquarter Site at
425 m elevation. Precipitation samples are collected every Tuesday
morning. pH and conductivity are measured at the site, and the samples
mailed to a Central Chemical Laboratory at the University of
Illinois. Samples are analyzed for Ca, Mg, K, Na, NH4, NO3, SO4, PO4,
pH, and conductivity. The dry precipitation bucket is collected the
first Tuesday of every even month and mailed to the University of
Illinois for the same analyses.

The Andrews Forest is in the western Cascade Range of Oregon in the
15,800-acre drainage basin of the Lookout Creek, a tributary of Blue
River and the McKenzie River. The area elevation ranges from 1350
feet to 5340 feet and contains excellent examples of Pacific Northwest
conifer forests, wildlife, and ecosystems.
