Attributes for MRB_E2RF1 Catchments by Major River Basins in the Conterminous United States: Normalized Atmospheric Deposition for 2002, Total Inorganic Nitrogen
This tabular data set represents the average normalized atmospheric (wet) deposition,
in kilograms per square kilometer multiplied by 100, of Total Inorganic Nitrogen for the
year 2002 compiled for every MRB_E2RF1 catchment of selected Major River Basins
(MRBs, Crawford and others, 2006). Estimates of Total Inorganic Nitrogen deposition
are based on National Atmospheric Deposition Program (NADP) measurements
(B. Larsen, U.S. Geological Survey, written. commun., 2007). De-trending methods
applied to the year 2002 are described in Alexander and others, 2001. NADP site
selection met the following criteria: stations must have records from 1995 to 2002
and have a minimum of 30 observations.
The MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental
Protection Agency's (USEPA) ERF1_2 and include enhancements to support national
and regional-scale surface-water quality modeling (Nolan and others, 2002; Brakebill and
others, 2011).
Data were compiled for every MRB_E2RF1 catchment for the conterminous United States
covering New England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee (MRB2),
the Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the Missouri (MRB4),
the Lower Mississippi, Arkansas-White-Red, and Texas-Gulf (MRB5), the Rio Grande, Colorado,
and the Great basin (MRB6), the Pacific Northwest (MRB7) river basins, and California (MRB8).
