Summary

This tabular data set represents PRISM 30-year average (1961-1990) relative humidity (percent) compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data for 30-year average (1961-1990) relative humidity (percent) was originally PRISM-based data, with some further enhancements by ClimateSource.com and then provided to the USGS by the Environmental Protection Agency (Ryan Hill, EPA, written commun., 2011). It should be noted this data set is discontinued and may [...]

Purpose

This data set was created by the U.S. Geological Survey's (USGS) National Water-Quality Assessment Project (NAWQA) which is part of the USGS National Water Quality Program (NWQP). This effort was undertaken to estimate the 30-year average (1961-1990) relative humidity (percent) for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
