AGU Chapman Conference on Advances in Lagrangian Modeling of the Atmosphere
Grindelwald, Switzerland
9
– 14 October 2011
Conference Objectives and General Description
Trajectory-based ("Lagrangian") atmospheric transport and dispersion modeling has gained in popularity and sophistication over the previous several decades. It is common practice now for researchers around the world to apply Lagrangian models for a wide spectrum of applications. Examples include:
- Assessing cross-border transport and chemical transformation of pollutants that adversely impact air quality;
- Inferring emissions of greenhouse gases from concentration data
- Probing regions potentially affected by releases of nuclear accidents or bio-weapons
- Quantifying stratosphere-troposphere exchange
- Identifying sources of moisture available for precipitation
Despite the value of Lagrangian models available today, numerous scientific issues remain. Among these, the following lists some of the most prominent scientific questions that need to be addressed in order to advance Lagrangian modeling:
- How can fundamental physical principles be satisfied by Lagrangian models as they increase in complexity and sophistication?
- How can parameterizations of atmospheric processes in Lagrangian models be improved?
- How can uncertainties in Lagrangian simulations be assessed quantitatively?
- How can Lagrangian models be properly coupled to Eulerian NWP/GCM models?
- In what ways can Lagrangian models in the atmosphere be applied to answer scientific and societal questions regarding geophysical phenomena?
- What possibilities are available to validate and test Lagrangian models?
Time is ripe for a Chapman Conference that enables participants to take stock of recent advances in Lagrangian modeling, share ideas in the use of the model for the aforementioned atmospheric applications, examinecurrent shortcomings, and discuss ways to move Lagrangian models forward.
The conference will bring together international experts in developing, using, and testing Lagrangian models. The goal is to build a community of researchers involved with Lagrangian models who will continue to improve such tools for future atmospheric scientists. We will solicit submissions to an edited volume to be published by AGU and to facilitate dissemination of results emerging from the conference.
