Summary

This tabular data set represents monthly average precipitation values (millimeters) described in Wolock and McCabe (2018), compiled for the NHDPlus version 2 data suite (NHDPlusV2) for the conterminous United States for the years 1945 - 2015. Linkage of the precipitation data with NHDPlusV2 is achieved through the common unique identifier COMID. The precipitation values are estimated both for: 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. The reach catchment information characterizes data at the local scale, whereas the catchments accumulated through the river network characterize cumulative upstream conditions. The network-accumulated values are derived using two methods: 1) [...]

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 monthly average precipitation (millimeters) for NHDPlusV2 flowline catchments and upstream river networks to support statistical analyses, map display, and model parameterization.
