Summary

This metadata record describes the average of annual maximum duration of consecutive dry and wet days per event, where precipitation totals are 0 or equal and exceeds 1 millimeters respectively, 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.

Purpose

This data set was created by the U.S. Geological Survey's (USGS) Hydrologic Systems Team which is part of the USGS National Water Quality Program (NWQP). The spatial variability of 30 year (1981 - 2010) annual maximum duration of consecutive dry and wet days is an important component with respect to water resources and hydrologic studies. Intensity and frequency of precipitation can affect river flow, evapotranspiration, soil moisture, and groundwater recharge (Huntington, 2006). This effort was undertaken to estimate the 30 year (1981 - 2010) annual average of daily intensity of precipitation for a rain event to support statistical analysis, map display, and model parameterization.
