Daily air temperature, relative humidity, vapor pressure, PPFD, wind speed and direction for climate stations at the Coweeta Hydrologic Lab, North Carolina

The data included consist of daily climatic information recorded at five climate stations at Coweeta Hydrologic Laboratory in Macon County, North Carolina, USA: CS01, CS17, CS21, CS28, and CS77. These stations are operated by the Southern Research Station, USDA Forest Service. Data include daily air temperature, relative humidity, barometric pressure (CS01 only), wind speed and direction, photosynthetically active photon flux density (PPFD), and solar radiation from 1983 through 2021 (starting year varies per climate station).
The Coweeta Hydrologic Laboratory was established in 1934 and is world-renowned for its research in forest hydrology. Coweeta was established to determine the fundamental effects of forest management on soil and water resources and to serve as a testing ground for theories in forest hydrology. To facilitate this, a network of climate and precipitation stations was established across the site. The research program has since expanded its focus to encompass watershed ecosystem science. The original climate and precipitation network continues to facilitate these studies and serves as the foundation of the long-term data record.
