The Mt. Bachelor Observatory is located at the Mt. Bachelor Ski Area and is run with the cooperation of Mt. Bachelor, Inc. An isolated volcanic peak with a summit at 2.7 km asl, Mt. Bachelor is a choice location for an atmospheric observatory. At this altitude, the observatory receives mostly free tropospheric air and sometimes stratospheric air, enabling us to sample air which has been relatively undisturbed during transport from Asia. The tradeoff with working at this location and altitude is the frequency of foul weather in the winter. Rime buildup on the (heated!) anemometer is a problem we are still dealing with.
