We have introduced additional NO y sources caused by energetic electron precipitation (EEP) during 1987 into a Chemistry‐Climate model. Comparison of two model runs with and without EEP reveals increase reactive nitrogen about 2 ppbv in the middle stratosphere over tropical latitudes. In upper polar winter regions simulated enhancement reaches 10 ppbv. Decreases ozone mixing ratio up to 5% midlatitudes 30% southern high‐latitudes are calculated. A ∼0.5 K cooling tropics is calculated...
Abstract. We describe version 2.0 of the chemistry-climate model (CCM) SOCOL. The new includes fundamental changes transport scheme such as transporting all chemical species individually and applying a family-based correction for mass conservation nitrogen, chlorine bromine groups, revised ozone, furthermore more detailed halogen reaction deposition schemes, cirrus parameterisation in tropical tropopause region. By means these manages to overcome or considerably reduce deficiencies recently...
Atmospheric effects of the solar irradiance variations during 11‐year cycle are investigated using a chemistry‐climate model. The model is enhanced by more detailed parameterization oxygen and ozone UV heating rates. simulated response to imposed forcing shows positive correlation in tropical stratosphere negative mesosphere, agreement with theoretical expectation. suggests an acceleration polar night jets both hemispheres dipole structure temperature changes at high latitudes. results also...
Abstract. In this paper we document "SOCOL", a new chemistry-climate model, which has been ported for regular PCs and shows good wall-clock performance. An extensive validation of the model results against present-day climate data obtained from observations assimilation sets that describes climatological state atmosphere late 1990s with reasonable accuracy. The significant temperature bias only in upper stratosphere near tropopause at high latitudes. latter is result rather low vertical...
This study analyses the wide-band algorithm, Cloud-J v.8.0, from point of view validity choice wide spectral intervals to accelerate calculations photolysis rates in lower and middle atmosphere, considering features solar radiation propagation, assess influence processes reflection scattering on molecules, aerosols, clouds. The results show that performed using v.8.0 are agreement with data obtained high-resolution LibRadtran model. also considers factors influencing propagation flux through...
Abstract. The chemistry-climate model (CCM) SOCOL has been used to evaluate the contributions of main anthropogenic factors simulated changes ozone and stratospheric dynamics during 21st century. As we consider atmospheric concentration greenhouse gases (GHG), depleting substances (ODS) sea surface temperature ice (SST/SI). latter is considered here as an independent factor because majority CCMs prescribe its evolution. We have performed three sets "time slice" numerical experiments for...
An algorithm for identification of the parameters, making part parabolic law that is often used predicting dependence interphase layer thickness on retention time in composite material structure based a metal matrix suggested. A generalized presentation this allows impact incubation period used; at same reaction rate constant estimated by Arrhenius relationship and takes into account pressure effect. The suggested transformation available introduction minimized objective function special...
