Stratospheric water vapour as tracer for Vortex filamentation in the Arctic winter 2002/2003
Stratospheric water vapour Vortex filamentation Arctic winter
2009/3/11
Balloon-borne frost point hygrometers measured three high-resolution profiles of stratospheric water vapour above Ny-Ålesund, Spitsbergen during winter 2002/2003. The profiles obtained on 12 Dec...
Trace gas transport in the 1999/2000 Arctic winter: comparison of nudged GCM runs with observations
Trace gas transport Arctic winter nudged GCM runs
2009/2/20
We have compared satellite and balloon observations of methane (CH4) and hydrogen fluoride (HF) during the Arctic winter 1999/2000 with results from the MA-ECHAM4 middle atmospheric general circulatio...
Simulation of denitrification and ozone loss for the Arctic winter 2002/2003
ozone loss Arctic winter denitrification
2009/2/11
We present simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS) for the Arctic winter 2002/2003. We integrated a Lagrangian denitrification scheme into the three-dimensional vers...
Ozone loss derived from balloon-borne tracer measurements in the 1999/2000 Arctic winter
Ozone loss balloon-borne tracer measurements Arctic winter
2009/2/10
Balloon-borne measurements of CFC11 (from the DIRAC in situ gas chromatograph and the DESCARTES grab sampler), ClO and O3 were made during the 1999/2000 Arctic winter as part of the SOLVE-THESEO 2000...
Influence of mountain waves and NAT nucleation mechanisms on polar stratospheric cloud formation at local and synoptic scales during the 1999-2000 Arctic winter
mountain waves NAT nucleation mechanisms polar stratospheric cloud formation Arctic winter
2009/2/7
A scheme for introducing mountain wave-induced temperature pertubations in a microphysical PSC model has been developed. A data set of temperature fluctuations attributable to mountain waves as comput...
Chemical ozone loss in the Arctic winter 2002/2003 determined with Match
Chemical ozone loss Arctic winter
2009/1/13
The Match technique was used to determine chemically induced ozone loss inside the stratospheric vortex during the Arctic winter 2002/2003. From end of November 2002, which is the earliest start of a ...
Partitioning between the inorganic chlorine reservoirs HCl and ClONO2 during the Arctic winter 2005 from the ACE-FTS
inorganic chlorine reservoirs HCl ClONO2 Arctic winter
2009/1/9
From January to March 2005, the Atmospheric Chemistry Experiment high resolution Fourier transform spectrometer (ACE-FTS) on SCISAT-1 measured many of the changes occurring in the Arctic (50–80° N) lo...
Observation of unusual chlorine activation by ground-based infrared and microwave spectroscopy in the late Arctic winter 2000/01
unusual chlorine activation microwave spectroscopy late Arctic winter
2009/1/5
During the Arctic winter of 2000/01, ground-based FTIR and millimetre-wave measurements revealed significant amounts of ClO over Kiruna after the final warming in February 2001. In fact, column amoun...
SAGE III aerosol extinction validation in the Arctic winter: comparisons with SAGE II and POAM III
aerosol extinction Arctic winter SAGE II POAM III
2008/12/3
The use of SAGE III multiwavelength aerosol extinction coefficient measurements to infer PSC type is contingent on the robustness of both the extinction magnitude and its spectral variation. Past vali...
Model simulations of stratospheric ozone loss caused by enhanced mesospheric NOx during Arctic Winter 2003/2004
stratospheric ozone mesospheric NOx Arctic Winter
2008/11/19
Satellite observations show that the enormous solar proton events (SPEs) in October–November 2003 had significant effects on the composition of the stratosphere and mesosphere in the polar regions. Af...
Chemical ozone loss in winter 1991–1992 is recalculated based on observations of the HALOE satellite instrument, Version 19, ER-2 aircraft measurements and balloon data. HALOE satellite observations a...
