SUCCESS
The DC-8 and ER-2 flew a coordinated mission over Boulder, Co. to sample a wave-cloud and study the effects of the DC-8 exhaust and contrails on the wave-cloud. The DC-8 flew in and out of the wave-cloud while the ER-2 flew above. Measurements were coordinated with the NOAA-14 satellite overpass at 4 UTC.

Wave Structure (96502)
In the following gif images, several fields are plotted versus distance along DC-8 flight tracks upwind of the wave-cloud. Plots are shown for each of the 4 legs aligned with the wind. The fields plotted are:
96/05/01 CART site activity
Meteorology at the Central Facility
The DC-8, T-39 and B757 flew a coordinated mission north of Albuquerque, NM. to sample in and near a wave-cloud and the B757 emissions. The DC-8 sampled the B757 exhaust, not closer than ten miles. The T-39 d B757 exhaust sampling after both aircraft left the New Mexico airspace while DC-8 continued wave-cloud sampling.
Flight Reports
DC-8 SUCCESS flight #211 [960211] (scientists: Brian Toon and Eric Jensen)
The DC-8 and T-39 flew a coordinated mission over the CART site to profile stratus clouds and aerosols, and to provide data (FSSP) which will be useful for CART site radar systems calibration. The T-39 sampled the DC-8 exhaust at various altitudes, penetrating the stratosphere.

96/04/28 CART site activity
Meteorology at the Central Facility
The DC-8, T-39 and ER-2 flew a coordinated mission over the CART site to profile optically thick cirrus, and to make coordinated measurements with the NOAA-14 satellite overpass at 1947 UTC. The DC-8 ascended in an up and down wind racetrack pattern before descending in slow spirals. The T-39 and DC-8 took turns sampling each others emissions and contrails. The ER-2 flew a racetrack pattern approximately ten degrees off the DC-8 orientation and in the opposite directions.
The T-39 and ER-2 flew separate missions. The T-39 sampled the emissions of commercial airliners (B757 and B727) at cruise altitudes of approximately 35kft. The ER-2 observed cirrus and contrails over Kansas and made coordinated measurements with the NOAA-14 satellite overpass at 1958 UTC.
Highlights
96/04/25 CART site activity
Meteorology at the Central Facility
The DC-8 and T-39 flew a coordinated mission over the CART site to profile cirrus clouds and for the T-39 to do near-field sampling of the DC-8 exhaust plume. Cirrus cells were observed the entire flight. While the DC-8 flew up and down wind tracks over the CART site, at different altitudes, the T-39 sampled its exhaust. Cirrus profiling was accomplished by the DC-8 by flying a racetrack pattern, in the up and down wind direction, while ascending, and then descending in slow spirals.
