Summary of LBA-MIP Informal Meeting at Fall 2007 AGU
Updated February 1, 2008
Most of the organization team and relevant participants
(see list below) could attend and we made great progress on
decisions, technical issues and future plans. One of the main
topics was the issues with the drivers we found during our First
Workshop in Salvador, BA Brazil last September and thanks to Natalia
Restrepo and Reto Stöckli (among others) we were able to fix the
drivers. Other issues were also discussed and changes were made to the
other datasets as well as some procedures in the protocol as listed below
(see protocol for detailed
- Drivers are now fixed and available immediately (see protocol for
- MODIS LAI will be replaced in all sites by a constant value which
is a MODIS annual average. A non-mandatory recommendation is to use
Reto Stöckli’s phenology model LAI and/or MODIS monthly LAI for
sensitivity analysis. Both datasets will be made available along with
the other drivers.
- There should be no precipitation sensitivity analysis during
- CO2 will be set to 375 ppm for all sites.
- Initial CO2 values will also be assumed
as steady-state solution (i.e., long spin-up).
- Groups are free to decide on the approach for leap year. The drivers
will be distributed with leap year.
- Percentage of silt, sand and clay for each soil class will be
distributed for all sites.
- Each group may prescribe the model parameters (e.g., rooting
depth) that better suits. Therefore the parameters table used for each
site and run as well as other model assumptions should be reported.
- One or more tools for converting ASCII data to NetCDF will be posted
along with the drivers.
- Groups may upload models source code if desired.
