polar stratospheric ozone the Arctic winters
2010/10/21
The polar stratospheric ozone loss during the Arctic winters 2004/2005–2009/2010 is investigated by using high resolution simulations from the chemical transport model Mimosa-Chim and observations fro...
A closer look at Arctic ozone loss and polar stratospheric clouds
Arctic ozone loss polar stratospheric clouds
2010/9/21
The empirical relationship found between column-integrated Arctic ozone loss and the potential volume of polar stratospheric clouds inferred from meteorological analyses is recalculated in a self-cons...
Estimation of Antarctic ozone loss from ground-based total column measurements
Antarctic ozone ground-based total column measurements
2010/8/16
The passive tracer method is used to estimate ozone loss from ground-based measurements in the Antarctic. A sensitivity study shows that the ozone depletion can be estimated within an accuracy of ~4%....

2009/11/19
The impact and significance of uncertainties in model calculations of stratospheric ozone loss resulting from known uncertainty in chemical kinetics parameters is evaluated in trajectory chemistry sim...
Peroxy radicals in the summer free troposphere: seasonality and potential for heterogeneous loss
Peroxy radicals summer free troposphere heterogeneous loss
2009/3/31
The sum of peroxy radicals (HO2+ΣiRiO2) and supporting trace gases were measured on the Jungfraujoch (3580 m a.s.l.) during the late summer of 2005. The period was marked by extended times of heavy sn...
The impact of mid-latitude intrusions into the polar vortex on ozone loss estimates
mid-latitude intrusions polar vortex ozone loss estimates
2009/3/10
Current stratospheric chemical model simulations underestimate substantially the large ozone loss rates that are derived for the Arctic from ozone sondes for January of some years. Until now, no expla...
Ozone loss and chlorine activation in the Arctic winters 1991-2003 derived with the tracer-tracer correlations
Ozone loss chlorine activation Arctic winters tracer-tracer correlations
2009/3/9
Chemical ozone loss in the Arctic stratosphere was investigated for the twelve years between 1991 and 2003 employing the ozone-tracer correlation method. For this method, the change in the relation be...
Impact of palmitic acid coating on the water uptake and loss of ammonium sulfate particles
palmitic acid ammonium sulfate particles
2009/2/12
While water insoluble organics are prevalent in the atmosphere, it is not clear how the presence of such species alters the chemical and physical properties of atmospheric aerosols. Here we use a com...
