Lb. Callis et al., A 2-D MODEL SIMULATION OF DOWNWARD TRANSPORT OF NOY INTO THE STRATOSPHERE - EFFECTS ON THE 1994 AUSTRAL SPRING O-3 AND NOY, Geophysical research letters, 23(15), 1996, pp. 1905-1908
Simulations using SAMPEX and HALOE data suggest that NOy produced by t
hermospheric processes and by relativistic electron precipitation in t
he mesosphere and lower thermosphere have been important to stratosphe
ric NOy and O-3 during the austral spring in 1994. The relative import
ance of the two NOy sources is discussed. The results are supported by
an analysis of HALOE NOy and CH4 data during October 1994 and are in
agreement with ATMOS NOy observations made in November 1994.
