Temperature Variations at 10,000 ft

Sampling Precision to Depth 10000: Evaluation Experiments at CLEF 2007

We describe evaluation experiments conducted by submitting retrieval runs for the monolingual Bulgarian, Czech and Hungarian information retrieval tasks of the AdHoc Track of the Cross-Language Evaluation Forum (CLEF) 2007. In the ad hoc retrieval tasks, the system was given 50 natural language queries, and the goal was to find all of the relevant documents (with high precision) in a particular...

Temperature Variations during the Last Century at High Elevation Sites

Differential temperature changes with altitude can shed light on the relative importance of natural versus anthropogenic climatic change. There has been heightened interest in this subject recently due to the finding that high-elevation tropical glaciers have been retreating and that significant melting from even the highest alpine regions has occurred in some areas during the past 20 years or ...

Seasonal variations of the atmospheric temperature structure at South Pole

[1] Fe/Rayleigh lidar measurements are combined with the high-altitude balloonsonde data and used to characterize the seasonal variations of atmospheric temperature at South Pole from the surface (2.835 km) to 110 km altitude. Twelve-month oscillations, associated with solar UV absorption by ozone, dominate the seasonal variations of temperature throughout the stratosphere and lower mesosphere ...

Reentry-f Flowweld Solutions at 80,000 Ft. Reentry-f Flowweld Solutions at 80,000 Ft

Three equilibrium-air numerical solutions are presented for the Reentry-F ight-test vehicle at Mach 20, 80,000 ft. conditions, including turbulent t o w predictions. The three solutions are from a thin-layer Navier-Stokes code, coupled thin-layer and parabolized Navier-Stokes codes, and an approximate viscous shock-layer code. Boundary-layer and shock-layer prooles are presented and compared be...
