For more details contact Dan Wolfe, 303-497-6204
In Case of Emergency (including tower light outage), contact Security Dispatch Center: 303-497-3530.

The BAO is a research facility in Erie, Colorado maintained by the Physical Sciences Division, which 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 that greatly reduces analysis time for scientists. The BAO has been the host of several large national and international experiments and numerous smaller ones.
