Summary

This metadata record describes 19 annual Congestion Mitigation and Air Quality Improvement (CMAQ) Program variables ( kilograms per hectare) for each year between 2002 - 2012 ( Zhang and others, 2012, Schwede and others, 2014) compiled for two spatial components of the NHDPlus version 2.1 data suite hereto referred to as (NHDV2) 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 NHDPlusv2 data suite by the unique identifier COMID. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions. Network-accumulated [...]

Purpose

These data were created by the U.S. Geological Survey's (USGS) for the USGS National Water Quality Program (NWQP) to map the percent of wet and dry deposition from Congestion Mitigation and Air Quality Improvement (CMAQ) Program for the years 2002 - 2012.
