Data
Temperature, ozone and humidity profiles measured above Table Mountain Facility, CA during the UAV flights:
Temperature - Lidar profiles obtained from our stratospheric ozone system. The fundamental quantity measured is T as a function of geometric altitude (columns 1 and 2, max range 15-95 km).
Ozone - Lidar profiles obtained from our stratospheric ozone system ("TMF", max range 15-55 km) and our tropospheric ozone system ("TMO", max range 5-27 km). The fundamental quantity measured is O3 number density as a function of geometric altitude (columns 1 and 2).
PTU Sonde Profiles - obtained from Vaisala radiosonde launches. The fundamental quantity measured is temperature and RHw as a function of pressure (columns 3, 4, and 5, max range 1000-70 hPa).

Plot #1: Ozone and atmospheric pressure attest to the sampling of stratospheric air
Ozone (red markers, right axis scale) and atmospheric pressure (blue markers, left hand scale) versus time (UTC) on April 26, 2005. This flight was conducted far above (<45,000 ft) the high desert of California near Palmdale and Victorville. Ozone measured in situ by the OZ instrument increased dramatically, starting at about 17:00 UTC, when Altair ascended from the troposphere through the tropopause (pressure ~100 mb) and entered the lower stratosphere. In this case, high ozone indicates air masses influenced by the stratosphere, where ozone is naturally produced.
Plot #2: Anticorrelation between ozone and CFC-11 verifies the sampling of stratospheric air masses
Ozone (red markers, right axis scale) and CFC-11 (black markers, left axis scale) versus time (UTC) on April 19, 2005, above Palmdale-Victorville, CA. Significant increases in ozone and coincident decreases in CFC-11 were measured in situ by the GC and OZ instruments as Altair ascended through stratosphere-influenced air masses (~5:00 PM), with reciprocal decreases in ozone and increases in CFC-11 during descent back to the troposphere at ~7:00 PM. The anticorrelation between ozone and CFC-11 (i.e., ozone increases as CFC-11 decreases and vice-versa) results from ozone being produced in the stratosphere and CFC-11, released by humans in the troposphere, being destroyed in the stratosphere. Hence, higher ozone and lower CFC-11 abundances indicate that Altair passed through air masses of stratospheric origin.
