NCAR/EOL 5 minute ISFS surface flux data


This dataset contains quality-controlled 5 minute averages of surface flux data collected by the NCAR/EOL Integrated Surface Flux System (ISFS) at 12 sites during the Great Plains Irrigation Experiment (GRAINEX) in southeast Nebraska. These data have been quality-controlled and are available in NetCDF format. Winds reported by the sonic anemometers have been tilt corrected and rotated into geographic coordinates.

Note: We are aware of a time stamping issue in some of the data and are currently working on a fix. We expect to release an updated version of these data as soon as possible. At this time we believe the current data to be accurate and mostly complete, but some changes in the next release are possible.
