Summary

This metadata record describes the annual average duration of consecutive wet and dry 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.

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 consecutive dry (CDD) days and consecutive wet (CWD) days is an important component with respect to water resources and hydrologic studies. This effort was undertaken to estimate the 30 year (1981 - 2010) annual average number of consecutive dry and wet days to support statistical analysis, map display, and model parameterization.
