Comparison of satellite and in situ ozone measurements in the lower stratosphere

Autor: Ellis E. Remsberg, T. Duncan Fairlie, Gretchen Lingenfelser, R. Bradley Pierce, William L. Grose

Publikováno v: Journal of Geophysical Research: Atmospheres. 104:13971-13979

An air parcel trajectory model with chemistry initialized using data obtained by the Halogen Occultation Experiment (HALOE) has been demonstrated to be an effective tool for studying chemical and transport processes in the lower stratosphere. One of

HALOE observations of the Arctic Vortex during the 1997 spring: Horizontal structure in the lower stratosphere

Autor: R. Bradley Pierce, James M. Russell, William L. Grose, T. Duncan Fairlie, Ellis E. Remsberg

Publikováno v: Geophysical Research Letters. 24:2701-2704

In late March, 1997, HALOE observed very low ozone (less than 1 ppmv at 480K), low HCl, generally high NO x , and normal levels of H 2 O within the Arctic vortex. Trajectory mapping techniques show that the lower stratospheric Arctic vortex was local
