Raw upper air data is routinely ingested by numerical models.

The really cold Arctic air is only in the lowest regions of the atmosphere (below say 5,000 feet), which GISS would fully see, while the satellite also sees air above 5,000 feet and averages that «warmer» upper air with the cold surface air.

Air pollution generated in Pennsylvania, Ohio and Kentucky is carried by upper air currents across the mountaintops of the Adirondack Park, leading to smog, a problem more associated with urban areas.

A number of statistical downscaling techniques (see Section 13.4 and Chapter 10, Section 10.6, for definition) used in scenario development employ Numerical Weather Prediction (NWP) reanalysis data products as a source of upper air climate data (Kalnay et al., 1996).

I suggest a flaw in analysis which is the apparent segmentation of the Upper Air profile, in the Arctic, the real action is happening between 1000 and 650 mb, segmenting upper air levels 850,700, and 500 mb reduces resolution and misses some real important air volumes at higher pressures, where anything can happen between 1000 and 850, 850 and 750 mb etc... Raobcore profile looks a little unrealistic, and it is likely that the models are more correct for the lower troposphere than Raobcore.

In a movie that purports to depict post-World War I life as it was in that «freer and upper air,» it is ironic — and incomprehensible — that Lindbergh is given no mention.

Tau Boötis A spins fast and emits ultraviolet radiation, which destroys compounds in the planet's upper air that would otherwise absorb starlight, heat up, and cause the temperature to rise with altitude.

However, it is worse during periods of warmer, sunnier weather when the upper air is warm enough to inhibit vertical circulation.
