✦ Synopsis

Soundings of vertical profiles of atmospheric temperature were conducted above an aluminium smelter and anearby paddock during twonights when stableconditions induced nocturnal radiation inversion formation.

On both nights the sky was cloudless, the surface wind speed was generally less than 2 m s-', and process heat produced surface temperatures at the smelter up to 6 C" higher than the paddock. This temperature excess decreased in magnitude up to a height of approximately 100 m, after which the protiles became similar. In addition, the inversion (4-6 C" increase in lowest 100-200 m) which formed above the paddock on these nights was prevented from occurring in the lowest 100 m above the smelter, where unstable temperature lapse rates prevailed.
