Summary

This tabular data set represents 30 year average (1961-1990) of maximum monthly number of days of measurable precipitation per month 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) of maximum monthly number of days of measurable precipitation 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., [...]

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) of maximum monthly number of days per month of measurable precipitation for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
