CHATS ISS SODAR Data
https://data.eol.ucar.edu/dataset/129.004

Summary
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. The main sonic array was supplemented with a 30-m
vertical profile of 16 sonic anemometers and 12 hygrothermometers, extending
from near the surface, through the canopy and roughness sublayer, to well
above canopy top. Also requested are fast-response static pressure sensors and
hot-wire/film anemometers to be collocated with the sonic anemometers in the
horizontal array, as well as a digital camera system to measure leaf area
index (LAI). Finally radiation and soil measurements were made to complete the
thermal energy budget of the canopy. 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.
