Confusion about the drive forcing

Hi all,

I am learning JULES based on a global suite u-as052.

If I want to customize my suite as 5-year spinup and 5-year run forced by GSWP3:
Could I set the [namelist:jules_spinup] is:
spinup_end=‘2005-12-31 21:00:00’
spinup_start=‘2000-01-01 00:00:00’

and the [namelist:jules_prescribed_dataset(1)] is:
data_end=‘2010-12-31 21:00:00’
data_period=-1
data_start=‘2000-01-01 00:00:00’

and the [namelist:jules_drive] is:
data_end=‘2010-12-31 21:00:00’
data_period=10800
data_start=‘2000-01-01 00:00:00’
file=‘/gws/nopw/j04/jules/GSW3-temp/drive_file2.txt’

I am not sure if GSW3-temp is suitable. Besides, I have no idea how to set [namelist:jules_prescribed_dataset(1)] and [namelist:jules_prescribed_dataset(2)] with which data.

In the original suite, they are set as:
file=‘/gws/nopw/j04/ncas_generic/users/pmcguire/jules_ancil/nancil_test_pljules-vn4.4/qrparm.veg.func_wfdei.nc’

Thanks if any comments.

Hi Yuan
Did you already request and obtain access to the ncas_generic group workspace, as suggested in the JULES FLUXNET tutorial?

That file:
file=‘/gws/nopw/j04/ncas_generic/users/pmcguire/jules_ancil/nancil_test_pljules-vn4.4/qrparm.veg.func_wfdei.nc’
contains the ancillary data for the vegetation on the WFDEI grid (0.5 degree LAT/LON spacing). As shown in the u-as052 suite, the variables used for the prescribed data sets for JULES are canht (canopy height) and lai (leaf_area_index).

For the GSW3-temp driving data file that you are trying to use, does that have a 10800-second data_period (3 hours)? Does it have the variable names listed in the jules_drive section of the file ~/roses/u-as052/app/jules/rose-app.conf ?

Hi again, Yuan:
Are you going through this tutorial for the jules global suite on JASMIN?:

Hi Patrick,

Thanks very much. I will try the global suite as soon as possible.

Best,
Yuan
