Probability of nitrate concentrations exceeding multiple thresholds of nitrate in shallow groundwater, Mid-Atlantic Region of the United States
Description
This data release consists of rasters representing the probability of exceeding multiple thresholds of nitrate in shallow groundwater for the Mid-Atlantic region of the United States. Each raster represents the results from multiple spatial-probability models that were developed using U.S. Geological Survey water-quality data in conjunction with geographic data such as land cover, geology, and soils. There are 10 rasters of predictions (PRED_1 through PRED_10) and 10 rasters of the highest possible probability (UPPER_1 through UPPER_10). The highest probability is the upper limit of the prediction confidence interval calculated as part of each model. Geospatial data provided are in the North American Albers equal-area conic projection at 1500-meter resolution.
Please refer to the Supplemental Information and Process Steps elements of this metadata record for specific geographic data layers and statistical processes.
