MOSES 2.2
The original version of MOSES 2.2 was a set of mods to version 4.5 of the Unifed Model, which were not formally added to the UM until around 5.2 (new dynamics). The code differs significantly from MOSES 2.1, with the boundary layer in particular being completely rewritten as a set of new decks.
The Hadley Centre documentation describes how to set up a MOSES 2.2 job. However, I suspect they refer to changes from MOSES 2.1 to MOSES 2.2, as a few extra fixes are required to upgrade from a MOSES 1 HadAM3 job.
The MOSES 2.2 base job which I set up is based on a standard HadAM3 run (xceya in the UMUI at Reading). The extra modsets and data files came from MOSES 2.2 users in the NCAS community.
Setting up a MOSES 2.2 job
Scientific sections
Select the following scientific options:
- SW Radiation: 3A
- LW Radiation: 3A
- Boundary Layer: 7A
- Hyrology: 7A
- Vegetation: 1A (fixed) or 2A (interactive)
To use spectral albedos select:
- SW Radiation -> Gen 2: "Including prognostic snow albedo"
Modsets
Include the following modsets:
abx0f406
abx1f406
abx2f406
abx3f406
abx4f406
amv1f406
apa1f406
are1f406
are2f406.1
are3f406
newdecks.1
scatter_fix
update_m22.mdk
initveg_fix.mod
To select the radiative canopy model include modset:
amv2f406
Hand edits
Include post-processing script or apply hand-edit moses2.2.ed:
sed -e '/LAND_FIELD/a\
NTILES=9,'\
$HOME/umui_jobs/$1/SIZES > het.$$
\mv het.$$ $HOME/umui_jobs/$1/SIZES
# if reconfiguration on
if [ -e "$HOME/umui_jobs/$1/RECONA" ]
then
sed -e '/LAND_POINTS/a\
NTILES=9,'\
$HOME/umui_jobs/$1/RECONA > het.$$
\mv het.$$ $HOME/umui_jobs/$1/RECONA
fi
To use aggregated tiles set NTILES=1.
STASH master files
Include the user stash master file moses2.2_ustash, which contains several tiled diagnostics and 5 new prognostics.
A domain profile with 9 psuedo levels on a single level had to be created for tiled diagnostics.
The prognostics should be initalised as follows:
Item Name Option 231 Snow grain size on tiles 1 233 Surface temp on tiles 1 234 Roughness length on tiles 1 235 Snow amount on tiles 1 236 Tile modified infiltration rate 3
Ancillaries and start data
MOSES 2.2 ancillaries are required for "Vegetation Distribution: Area and structure":
- Fractions of surface types
- LAI and height of plant functional types
Other ancillaries which may be affected:
- Soil moisture and snow depth
- Deep soil temperatures
- Soil parameters
In the example job, I used a start file from another MOSES 2.2 job and included the following ancillaries (copied from the same job):
- Soil parameters: soilparm.ukmo.ukmosoilalb - configured
- Fractions of surface types: qrfrac.igbp - configured
- Plant functional types: veg.phen.grn.ch.pft - LAI and Canpoy Height updated every day
To work out which ancillaries to include, I switched off all fields which were set to "configured" and ran the reconfiguration. I then switched back on the ancillaries which the reconfiguration complained about.
