Technical note: Recursive rediscretisation of geo-scientific data in the Modular Earth Submodel System (MESSy)

Author(s) : Jöckel, P.
Description : This technical note describes a method for the rediscretisation of "gridded" geo-scientific data. A recursive algorithm (NREGRID) is derived to solve the rediscretisation problem for orthogonal grids (including curvilinear) of arbitrary dimension. The algorithm is used within the program NCREGRID to...

What does the global mean OH concentration tell us?

Author(s) : Lawrence, M. G. , Jöckel, P. , Von Kuhlmann, R.
Description : The global mean OH concentration ([OH]GM) has been used as an indicator of the atmospheric oxidizing efficiency and its changes over time. It is also used for evaluating the performance of atmospheric chemistry models by comparing with other models or with observationally-based reference ...

Technical note: The new comprehensive atmospheric chemistry module MECCA

Author(s) : Sander, R. , Kerkweg, A. , Jöckel, P. , Lelieveld, J.
Description : In this technical note we present the multi-purpose atmospheric chemistry model MECCA. Owing to its versatility and modular structure, it can be used for tropospheric as well as stratospheric chemistry calculations. Extending the code to other domains (e.g. mesospheric or oceanic chemistry) is easil...

Technical note: Implementation of prescribed (OFFLEM), calculated (ONLEM), and pseudo-emissions (TNUDGE) of chemical species in the Modular Earth Submodel System (MESSy)

Author(s) : Kerkweg, A. , Sander, R. , Tost, H. , Jöckel, P.
Description : We present the submodels OFFLEM, ONLEM, and TNUDGE for the Modular Earth Submodel System (MESSy). Prescribed emissions from input files are handled by OFFLEM. ONLEM deals with online-calculated emissions, i.e., emissions that are calculated during the simulation. The submodel TNUDGE uses the "tracer...

Influence of different convection parameterisations in a GCM

Author(s) : Tost, H. , Jöckel, P. , Lelieveld, J.
Description : In global models of the atmosphere convection is parameterised, since the typical scale of this process is smaller than the model resolution. Here we address some of the uncertainties arising from the selection of different algorithms to simulate this process. Four different parameterisations for at...

Lightning and convection parameterisations ? uncertainties in global modelling

Author(s) : Tost, H. , Jöckel, P. , Lelieveld, J.
Description : The simulation of convection, lightning and consequent NOx emissions with global atmospheric chemistry models is associated with large uncertainties since these processes are heavily parameterised. Each parameterisation by itself has deficiencies and the combination of these substantially...

Technical Note: The Modular Earth Submodel System (MESSy) ? a new approach towards Earth System Modeling

Author(s) : Jöckel, P. , Sander, R. , Lelieveld, J.
Description : Generally, the typical approach towards Earth System Modeling has been to couple existing models of different domains (land, ocean, atmosphere, ...) offline, using output files of one model to provide input for the other. However, for a detailed study of the interactions and feedbacks between chemic...
