upper-air observation

A measurement of atmospheric conditions aloft, above the effective range of a surface weather observation. Also called sounding and upper-air sounding. This is a general term, but it is usually applied to those observations used in the analysis of upper-air charts (as opposed to measurements of upper-atmospheric quantities primarily for research).

Figure 1 shows the location of regional upper-air sounding systems, also indicating how spatially sparse and infrequent operational real-time observations were during the last five years.
Upper-air soundings were performed four times per day with an average of seven days per IOP.
In recent years, upper-air sounding efforts in the Southeast have been conducted by the University of North Carolina at Asheville; the University of North Carolina at Charlotte; the University of Alabama in Huntsville; Simmons Army Airfield in Fort Bragg, North Carolina; Redstone Arsenal in Huntsville, Alabama; and the National Oceanic and Atmospheric Administration (NOAA) Atmospheric Turbulence and Diffusion Division Laboratory in Oak Ridge, Tennessee, among others.
The tiered "system of systems" architecture envisioned for in situ upper-air soundings identified GRUAN as the reference tier, the GCOS Upper-Air Network (GUAN) as a baseline capability, and the remainder of the radiosonde network providing regional detail (Seidel et al.
