Abstract: 

We report here the chemistry of weekly wet-only rainfall from the Luquillo Experimental Forest (LEF) NADP station (code PR20) for the period February 1985 through December 1996. 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. //nadp.sws.uiuc.edu/nadpdata/state.asp?state=PR 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.

Methodology

Methods: 

Data files are divided into calendar years. One data row corresponds to each weekly sample. The data columns are starting and ending sampling dates (Year Month Day), ionic concentrations (in milligrams per liter ion weight), pH measured in lab and field, conductance (micromhos per centimeter) measured in lab and field, and depth of rain (millimeters). Missing samples or analyses are indicated with "--".
