Workplan, Meetings


The 2008 round of intercomparisons will be done without major human impacts (e.g. dams, irrigation). The plan is to include these human impacts in the next rounds. The total number of rounds including both LHSMs and GHMs will then be three, i.e.:

·         #1 (2008): Without human impacts (e.g. dams, irrigation), baseline simulations (i.e. using historical meteorological forcing data).

·          #2 (2009): With human impacts, baseline simulations (i.e. historical meteorological forcing data)

·          #3 (2009/2010): Future scenarios with human impacts.

 

#1 will be performed using the NCC (Ngo-Duc et al., 2005) forcing dataset (regridded to 0.5 degrees by Watch WB1, available at the Watch ftp site), while #2 and #3 will be performed using the forcing datasets that will be created by Watch WB1 and WB3.

Workplan 2008

During the workshop in April 2008, the following workplan for 2008 was decided upon:

 15 May: Forcing data and routing network available at the Watch ftp site

 15 May - 1 August:

Model runs   

 1 August - 1 September:         

Model simulation results should be submitted to the Watch ftp site preferably before 1 August, but definitely before 1 September

 3 - 4 November:

Discussion of results, and planning of the next model simulation rounds

The focus of the model intercomparison project in 2008 is the differences in model physics.

 

Meetings

To facilitate the intercomparison and to discuss results and protocols, a range of workshops are planned, with initially two workshops per year.

  1. 22 - 24 April 2008: in Wageningen (the presentations and minutes are posted on the Watch intranet, see Intranet - Workshops - Model intercomparison)
  2. 3 - 4 November 2008: in Bratislava (Before the Watch project General Assembly)
  3. March / April 2009: to be organised by GWSP.
  4. November 2009: linked to the Watch project General Assembly.
