Description
The BAO research facility in Erie, Colorado is used for studying the planetary boundary layer and for testing and calibrating atmospheric sensors. Ongoing measurements include solar radiation and greenhouse gases. The centerpiece of the facility is a 300-m tower instrumented at multiple levels with slow-response temperature, relative humidity and wind sensors, a profiling instrument carriage, a variety of remote sensing systems, and a real-time processing and display capability.
