Corporate computing and storage systems supporting the EOL data archive will be powered off for maintenance and unavailable 26 July to 02 August 2021. The EOL data archive website should remain up and available however some connectivity outages may occur. Most data orders and downloads will not be available. Please try again after 03 August 2021.

NCAR/EOL 5 minute ISFS surface flux data, tilt corrected, geographic coordinate winds


Tilt corrected 5 minute averages of surface flux data collected by the NCAR/EOL Integrated Surface Flux System (ISFS) during the CHEESEHEAD field campaign. These data have been quality controlled and are available in NetCDF format. The winds reported by the sonic anemometers have been rotated into geographic coordinates and corrected for the orientation of the sonic anemometers. The tilt corrections applied were determined by the use of laser multi-station scans of the position and orientation of the sonic anemometers with respect to gravity.

Note: A companion dataset is available that corrects for sonic orientation with respect to flow through the sensor.

Disclaimer: GPS positions of stations are not included in this dataset, but can be found at the ISFS Operations at CHEESEHEAD page linked below.

Additional information

Data Quality final
  • 0.1 (2019-10-23)
  • 0.2 (2019-11-26):

    Additional derived variables for fluxes, radiation, and soils are included.

  • 1.0 (2020-04-20)
  • 2.0 (2021-01-14):

    Corrected radiation parameters from NR01 sensors.

  • 2.1 (2021-03-01):

    Recovered good soil thermal properties data from TP01 sensor at NE4. These data had been removed from previous dataset versions during QC.
