FAMOUS

XCPSA FAMOUS release

throughout, xbyva=xcpsa (HPCx) and xbyvq=xcpsb (QUEST) - those are just my job names. And for those of you really paying attention, these Dec07 pages are fundamentally the same as the Summer07 pre-release ones, but the instructions reflect new changes to UMUI 4.5.3.

Caveats:

1) we don’t have bit-reproduceability on QUEST

2) there’s a mystery salinity drift on QUEST: in a run that’s been artificially forced to have zero net salinity flux at the surface my global ocean average is losing 0.1psu per 1000yrs

3) the ocean state is not spun up well for the marine biogeochemistry: the ocean is still outgassing CO2 in this setup.

4) The MEAD diagnostics are broken on QUEST



Decadal means for the first one hundred years of QUEST run can be found on PUMA at /home/famous/data/ if you wish to check your setup. The bit reproduceability issues on QUEST mean that you won’t get identical results, but the climates should be statistically the same.

I’m more than happy to answer queries and provide help, but it’s probably more transparent all round if questions get routed through the helpdesk, so they can be logged and tracked properly - make sure you select “FAMOUS” as the UM component on the help form.


Excluding the marine biogeochemistry, the physical climate here is the same as in the published XDBUA version. XDBUA is better spun up, but that make little difference to the surface climate. Global average CO2 sensitivity has already been found to be similar to that of HadCM3 (see Dec 07 Notes), a brief look at the spatial patterns of climate change under C02 forcing in FAMOUS has now been done.
