We present a statistical analysis of aircraft and
surface measurements of the CO2 mixing ratio over the US Rocky
Mountains during 1993 – 2002 at latitudes close to that of the Issyk-Kul
station in Kyrgyzstan.
Average characteristics of the CO2 mixing ratio and its annual
variations show only small height variability in the troposphere over well
mixed mountain regions. Comparison of Issyk-Kul
optical data with US aircraft and surface measurements shows satisfactory
agreement. Also some differences at low altitudes were obtained owing to
possible regional differences between mountain regions of Central Asia and USA.
