Summary

This tabular data set represents 30 year (1971 - 2000) mean annual temperature (Celsius) 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 (1971 - 2000) mean annual temperature (Celsius) was produced by the PRISM Group at Oregon State University (PRISM, 2008). Units are degrees celsius. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream [...]

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 (1971 - 2000) mean annual temperature (Celsius) for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
