CHATS: ISS SODAR Wind Profiler Products

Summary

This dataset contains Sound Detection and Ranging (SODAR) data collected by the NCAR/EOL Integrated Sounding System (ISS) during the CHATS campaign and is available in raw ASCII format. These data have not been quality-controlled.

The objective of CHATS was to make spatial measurements of the velocity and scalar turbulence fields in a uniformly vegetated canopy, using arrays of sonic anemometer/thermometers augmented with fast response water vapor and carbon dioxide sensors. With this spatial information, the three-dimensional fields of velocity and scalar fluctuations can be studied to quantify turbulence transport processes and coherent structures throughout the canopy layer. An ancillary goal was to characterize the turbulent structure of the fields of wind, temperature, humidity, and trace chemical species within and above the orchard canopy.
