Modelling and Prediction Projects

The GEWEX Modelling and Prediction Panel (GMPP), chaired by Prof. Christian Jakob, oversees development and improvement of cloud and land-surface parameterization schemes of GMPP Projects to ensure their successful integration into global circulation models.

GMPP Project Reports

Data Integration for Model Evaluation (DIME) - An ad hoc activitity to provide test kits for model evaluation based on GCSS model intercomparison projects, including detailed results from the participating cloud resolving models.
DIME Contact:  William Rossow

GMPP Projects Description
GABLS - GEWEX Atmospheric Boundary Layer Study
Contacts:  Bert Holtslag and Gunilla Svensson		 Coordinate research on boundary layer physics to improve the representation of the atmospheric boundary layer in models.


GCSS - GEWEX Cloud System Study
Contact: Pier Siebesma

 Develop new physically-based cloud parameterizations based on cloud resolving models of different cloud systems for numerical weather prediction and climate models. Develop models using existing and planned campaign data sets; conduct intercomparison workshops; and provide blueprints of cloud data requirements for new campaigns.

GCSS Working Groups
-Boundary Layer Clouds
Contact: Adrian Lock		 Improve physical parameterizations of clouds and cloud related processes and their interactions.
-Cirrus Cloud Systems
Contact: Steven Dobbie		 Improve the parameterization of cirrus cloud systems.
-Extra Tropical Layer Clouds
Contact: George Tselioudis		 Improve the parameterization of extra-tropical layer clouds within climate and large scale models.
-Precipitating Convective Cloud Systems
Contact: Jon Petch		 Improve the parametrization of precipitating convective cloud systems in global climate models and numerical weather prediction models through an improved physical understanding of cloud system processes.
-Polar Clouds
Contact: James Pinto		 Improve simulations of  the long-lived mixed-phase clouds found at the top of the Arctic planetary boundary layer.
-GPCI - GCSS Pacific Cross-section Intercomparison
Contact: Joao Teixeira		 Compare and evaluate the representation of clouds in climate and numerical weather prediction models, both global and regional, over the sub-tropical and tropical Pacific ocean.


GLASS - Global Land/Atmosphere System Study
Contacts: Bart van den Hurk and Martin Best
Coordinate the development of  improved  land-surface schemes for coupled land-atmosphere models at all scales.

GLASS Projects

-ALMA - Assistance for Land-surface Modelling Activities
Contact: Taikan Oki

 Provide a data exchange format that is general and flexible enough to evolve with the needs of land-surface schemes.
-GLACE-2 - Global Land-Atmosphere Coupling Experiment
Contact: Randal Koster		 Multi-model intercomparison experiment focusing on the ability of land-surface states to affect rainfall generation and other atmospheric processes.
-GSWP-2 - Global Soil Wetness Project
Contact: Paul Dirmeyer		 GSWP-2 is an ongoing environmental modelling research activity of GLASS.
-LoCo - Local coupled land-atmospheric Modelling
Contact:  Bart van den Hurk		 Understand, model and predict the role of local land-atmosphere coupling in the evolution of land-atmosphere fluxes and state variables, including clouds.
