Climate Data for the Mid-Atlantic Region

ChesWx Historical Climate Datasets (EXPERIMENTAL)

climate normals

Overview

The ChesWx gridded climate datasets contain daily interpolations of precipitation and temperature observations for the Chesapeake Bay watershed, as well as the broader Mid-Atlantic and surrounding regions. Data are available from 1948 to 2015 at 4-km spatial resolution. The precipitation dataset uses a unique interpolation approach based on machine learning and geostatistical methods to create improved representations of precipitation frequency and areal daily intensity. Before interpolation, all input station observations of precipitation are homogenized to ensure temporal consistency and interstation data compatibility. The temperature dataset includes daily minimum and maximum temperature from the Penn State TopoWx conterminous U.S. gridded temperature product. TopoWx provides gridded temperature estimates that accurately capture both (1) locally relevant topoclimate spatial patterns; and (2) regional climate variability and trends.
