Description |
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. |

|
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 |
The second phase of GLACE is aimed at quantifying, across a broad range of state-of-the-art forecast models, the subseasonal forecast skill associated with the initialization of land surface state variables. The design is based upon the successful pilot experiment (GLACE-1) and is built around a comprehensive suite of 60-day forecasts that are evaluated against observed precipitation and air temperature fields.
