Eddy-Covariance Measurements
CO2 and H2O are measured with
an EC155 Closed-Path Gas Analyzer.
Three-dimensional wind speed and sonic
air temperature are measured with a
CSAT3A sonic anemometer head.
The CPEC310 has two enclosures:
a fiberglass enclosure that houses
the CR6 datalogger, pump module,
three-valve module, and optional CDM-A116,
and the EC100 enclosure for data processing.
The CPEC310 can also be equipped with
a scrub module for automatic zeroing of the EC155.
