Abstract

Because of the importance of the planetary boundary height in determining pol- lutant concentrations near the surface, a study of the nocturnal boundary layer was carried out at the Central Nuclear de Almaraz (Spain). During the night there is a distinction between the turbulent or mixing layer (ML) height and the nocturnal cooling layer or nocturnal stable layer (NSL) height. A number of scales that measure the height of both layers were studied, finding that while the NSL height increases as the night progresses, the ML height does not show any trend. Also a number of secondary
