Help finding some model outputs

[anmcr]

Hi,

I am involved in a model intercomparison project. Some of the model outputs that I have been asked to supply I have been unable to find in the UM STASH. These are listed below. Could you please advise whether they are available, and if so give the STASH code.

Thanks,

Andrew

geopotential height on model levels
dew point temperature on model levels
turbulent kinetic energy on model levels
total cloud cover on model levels
water vapour path
albedo
surface snow thickness
surface temperature at atmosphere-cryosphere interface
surface temperature at ice-ocean interface
snow surface skin temperature

Hi Andrew,

You can check this using the following command,

grep -i geop /projects/um1/vn11.1/ctldata/STASHmaster/STASHmaster_A

which gives the result

1|    1 |   16 |  201 |GEOPOTENTIAL HEIGHT ON THETA LEVELS |
1|    1 |   16 |  202 |GEOPOTENTIAL HEIGHT ON P LEV/P GRID |
1|    1 |   16 |  255 |GEOPOTENTIAL HEIGHT ON RHO LEVELS   |
1|    1 |   20 |   33 |FREEZING LEVEL GEOPOTENTIAL HEIGHT  |
1|    1 |   20 |   36 |-20C ISOTHERM GEOPOTENTIAL HEIGHT   |
1|    1 |   20 |   61 |-70C ISOTHERM GEOPOTENTIAL HEIGHT   |
1|    1 |   30 |  207 |GEOPOTENTIAL HEIGHT ON P LEV/UV GRID|
1|    1 |   30 |  297 |GEOPOTENTIAL HEIGHT ON P LEV/T GRID |

So you can see that geopotential height on model levels is not available. Repeat for the other diagnostics.

Hi Andrew,

It seems that theta levels are equivalent to model levels and the STASH uses them interchangeably. Sorry for the confusion.

Hi Willie,

Thanks. This was useful.

Are you able to advise whether 'Roughness length after timestep' (26) is the roughness length for momentum or for heat?

Best wishes,

Andrew

Hi Andrew,

UMDP 024 discusses some aspects of roughness length.
