Attributes for NHDPlus Version 2.1 Flowlines for the Conterminous United States: 2012 Source Sector Deposition from Community Multiscale Air Quality modeling system (CMAQ)

Metadata Updated: October 28, 2023

This metadata record describes 4 tabular data sets that estimate fraction of the total dry or wet deposition due to emissions from fertilizer and animal manure based on output from the Community Multiscale Air Quality modeling system (CMAQ, Zhang and others, 2019) compiled for two spatial components of the NHDPlus version 2.1 data suite (hereto referred as 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 2.1 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 values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlusv2 reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018).
