Inclusion of additional data streams within atmospheric inverse modelling systems: first results from ITMS

Autor: Christoph Gerbig, Frank-Thomas Koch, Saqr Munassar, Danilo Custodio, Michal Galkowski, Christian Rödenbeck

Within the Integrated Greenhouse Gas Monitoring System for Germany (ITMS), a national initiative targeted at the provision of estimates of GHG fluxes for Germany, the CarboScope-Regional (CSR) inversion system operated at the MPI-BGC is envisioned as

Using aircraft observations of atmospheric CO2 to evaluate vertical transport within the CarboScope Regional inverse model

Autor: Danilo Custódio, Saqr Munassar, Frank-Thomas Koch, Christian Rödenbeck, Christoph Gerbig

This work was developed on the scope of the national initiative of the Integrated Greenhouse Gas Monitoring System for Germany – ITMS, which focus on reducing and characterizing uncertainties/errors introduced in the full retrieval chain of models,

Net ecosystem exchange (NEE) estimates 2006–2019 over Europe from a pre-operational ensemble-inversion system

Autor: Saqr Munassar, Christian Rödenbeck, Frank-Thomas Koch, Kai U. Totsche, Michał Gałkowski, Sophia Walther, Christoph Gerbig

Publikováno v: Atmospheric Chemistry and Physics

Three-hourly net ecosystem exchange (NEE) is estimated at spatial scales of 0.25∘ over the European continent, based on the pre-operational inverse modelling framework “CarboScope Regional” (CSR) for the years 2006 to 2019. To assess the uncert

Why do inverse models disagree? A case study with two European CO2 inversions

Autor: Saqr Munassar, Guillaume Monteil, Marko Scholze, Ute Karstens, Christian Rödenbeck, Frank-Thomas Koch, Kai U. Totsche, Christoph Gerbig

Publikováno v: Atmospheric Chemistry and Physics

We present an analysis of atmospheric transport impact on estimating CO2 fluxes using two atmospheric inversion systems (CarboScope-Regional (CSR) and Lund University Modular Inversion Algorithm (LUMIA)) over Europe in 2018. The main focus of this st

Impact of atmospheric transport on CO2 flux estimates derived from the atmospheric tracer inversions

Autor: Saqr Munassar, Guillaume Monteil, Marko Scholze, Ute Karstens, Christian Rödenbeck, Frank-Thomas Koch, Kai Uwe Totsche, Christoph Gerbig

We present an analysis of atmospheric transport impact on estimating CO2 fluxes using two atmospheric inversion systems (CarboScope Regional (CSR) and LUMIA) over Europe for 2018. The main focus of this study is to quantify the dominant drivers of sp

Fast Atomic Charge Calculation for Implementation into a Polarizable Force Field and Application to an Ion Channel Protein

Autor: Raiker Witter, Margit Möllhoff, Frank-Thomas Koch, Ulrich Sternberg

Publikováno v: Journal of Chemistry, Vol 2015 (2015)

Polarization of atoms plays a substantial role in molecular interactions. Class I and II force fields mostly calculate with fixed atomic charges which can cause inadequate descriptions for highly charged molecules, for example, ion channels or metall

Analysis of regional CO2 contributions at the high Alpine observatory Jungfraujoch by means of atmospheric transport simulations and δ13C

Autor: Ute Karstens, Stephan Henne, Martin Steinbacher, Béla Tuzson, Simone M. Pieber, Dominik Brunner, Lukas Emmenegger, Christoph Gerbig, Frank-Thomas Koch

Understanding of regional greenhouse gas emissions into the atmosphere is a prerequisite to mitigate climate change. In this study, we investigated the regional contributions of carbon dioxide (CO2) at the location of the high Alpine observatory Jung
