Abstract

We present an analysis of odd nitrogen species measured by the CRISTA
experiment during the Space Shuttle mission STS 66 in November 1994.
Observations of several nitrogen species are compared with modeled
fields obtained from three-dimensional simulations performed with a
chemical transport model (CTM). A sequential trace gas assimilation
system is used in order to constrain the simulations by CRISTA
observations of long-lived species, and total amounts of stratospheric
nitrogen (NOy) derived from measurements of individual nitrogen
components (NO2, N2O5, HNO3, and ClONO2). Comparisons of measured and
modeled NOy species focus on significant diurnal variations and intense
longitudinal variations observed by CRISTA.
