Aerography

Aerography is a surrealist method in which a stencil, which would have been used in spraypainting, is replaced by a three-dimensional object. Examples can be seen in the works of Man Ray.

Aerography is the production of weather charts. The information is supplied by radiosonde observations, principally. Constant-pressure charts are routinely constructed at standard air pressures. Standard air pressures are 850, 700, 500, 400, 300, 250, and 200 millibars (hectopascals) (hPa) (SI). Weather charts are sometimes drawn at lower air pressures that occur above 40,000 feet (c. 12km). The lines of equal air pressure are called isoheights. Isotherms are the lines of equal air temperature.
