RelatedUSDA-ARS-National Laboratory for Agriculture and the Environment Flux Sites
The IEM is pleased to host the data from a set of observing platforms operated by the USDA-ARS-National Laboratory for Agriculture and the Environment (NLAE). These sites directly measure and derive numerous air and soil flux values.
These raw data have not been subjected to the National Laboratory for Agriculture and the Environment's quality control or quality assurance procedures. The correction factor's are calculated within a Campbell Scientific, Inc (Logan, UT) provided flux program for the CR5000 dataloggers. The WPL corrections are based on the equations found in Webb, E.K., G.I. Pearman, and R. Leuning, 1980. Correction of flux measurements for density effects due to heat and water vapor transfer.
They are released for limited public use as preliminary data to be used only with appropriate caution. View variables collected from this network.
