Purpose

These data are part of a study to test causal hypotheses, using structural equation models, related to the drivers of total nitrogen and total phosphorus loads in the Chesapeak Bay Watershed, 1985-2012. These data represent a potential causal factors for total nitrogen and total phosphorus loads.
