30 year (1981 - 2010) annual average number of occurrences of dry and wet events for the Conterminous United States and District of Columbia

This metadata record describes the annual average number of occurrences of dry and wet events during the 30-year period 1981 – 2010 for the conterminous United States. A wet event is defined as a period when the number of consecutive days with precipitation equals or exceeds 1 millimeter. A dry event is defined as a period when the number of consecutive days with precipitation equals 0 millimeters. The source data was produced and acquired from DAYMET (2018) and is presented here as a 1-kilometer resolution GeoTIFF file.

30 year (1981 - 2010) annual average of daily intensity of precipitation for a rain event for the Conterminous United States and District of Columbia

This metadata record describes the average daily precipitation intensity for rain events during the 30-year period 1981 – 2010 for the conterminous United States. A rain event is defined as a period when the number of consecutive days with precipitation equals or exceeds 1 millimeter. Daily precipitation intensity is defined as the amount of precipitation over the duration of a rain event divided by the number of days in a rain event. The source data was produced and acquired from DAYMET (2018) and is presented here as a 1-kilometer resolution GeoTIFF file.

Inputs and Selected Predictions of the CBTN_v5 and CBTP_v5 SPARROW Models for the Chesapeake Bay Watershed

The CBTN_v5 and CBTP_v5 SPARROW models were developed to support inferences about causes of observed changes in nitrogen and phosphorus (respectively) fluxes in Chesapeake Bay tributaries between 1992 and 2012. Model inputs and outputs are included in three files, which are described below. Detailed documentation of the SPARROW modeling technique is available at https://pubs.er.usgs.gov/publication/tm6B3.

Proposed locations for expansion of the West Virginia streamgaging network

The U.S. Geological Survey (USGS) and the West Virginia Water Gaging Council have proposed an expansion to the existing West Virginia streamgage network. As of December 18, 2018, the USGS operates a network of 149 real-time streamgages in West Virginia. This geospatial dataset provides the approximate locations of 39 proposed streamgages. These streamgages include 31 presently operated by the West Virginia Division of Homeland Security and Emergency Management and 8 new streamgages. These streamgages may be relocated depending on access and stream conditions, and data users who need precise locations of these streamgages may contact the USGS office in Charleston, West Virginia.
