NADP/NTN precipitation chemistry data

This dataset links to the NADP data repository for the chemistry of weekly wet-only rainfall from the Luquillo Experimental Forest (LEF) NADP station (code PR20). Our station was knocked out by Hurricane Hugo in September 1989, and not reestablished until May 1991. The station remains in active service to the present and data from 1997 onwards is available directly from the NADP/NTN web site https://nadp.slh.wisc.edu/sites/ntn-PR20/. Samples are collected weekly on Tuesdays, field measurements of pH and conductivity are made, and the water sample is shipped to NADP for chemical analysis. Sub-samples are also shipped to the University of New Hampshire Water Quality Analysis lab and those data are available in the EDI dataset: https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-luq&identifier=174 Support for this work was provided by grants BSR-8811902, DEB-9411973, DEB-9705814 , DEB-0080538, DEB-0218039 , DEB-0620910 , DEB-1239764, DEB-1546686, and DEB-1831952 from the National Science Foundation to the University of Puerto Rico as part of the Luquillo Long-Term Ecological Research Program.
