Workshop in Stockholm 19-21 June 2007!


The second GABLS model intercomparison

The second intercomparison project from the GEWEX Atmospheric Boundary Layer Study (GABLS) aim to study the representation of the diurnal cycle over land in both 1D coloumn models and Large Eddy Simulations (LES). This page is designated to presenting the 1D model case. Separate instructions will be circulated for an LES study.
The case is based on three days from the CASES-99 experiment. The ambition is to keep the forcing conditions similar enough to the real conditions making it possible to compare the model results with the observations. However, the main aim is to inter-compare the various models performance.

Case description

The details of the case description can be downloaded here. The models are forced by surface temperature, geostrophic wind and large-scale subsidence. A few figures of observations and the surface forcing can be found on the right.

Frequently asked questions

What does "The latent heat flux at the surface is 2.5% of its potential value" mean?
- The potential latent heat flux is what you get from a water surface at the prescribed temperature.
