problem running WACCM with QBO configuration

[shujch03@lzu_cn]

Hi, we've built WACCM our computor. Recently, some advices let us kown WACCM also can't generate a QBO, but there is an undoocumened option to relax to specified QBO.Now,the informations about QBO can't be found in the home page of WACCM. We need a number of source codes and data file with the QBO winds in it, that need to run with the QBO. Appreciated for any advice on things!

To run with a forced QBO you need a modified version of the runtime_opts.F90 source file. This is now on the Community Data Portal at:

WACCM (Whole Atmosphere Community Climate Model) > WACCM-3 source code distribution > WACCM QBO

The namelist settings are:

qbo_use_forcing = .true.
qbo_cyclic = .false.
qbo_forcing_file = 'YOUR_INPUT_DATA_DIRECTORY/qboseries_1953-2007_c081015.nc'

The necessary data file is in the same location on the CDP.

The source file runtime_opts.F90 for the QBO namelist options had an error in it.

Line 921 should read:
namelist /camexp/ qbo_use_forcing, qbo_forcing_file, qbo_cyclic

The corrected file is on the Community Data Portal
