Hi,
I want to output additional daily variables for a ACCESS-CM2 simulation. All but one variable are listed in the STASH request list, so I can just tick them. For surface pressure, however, I don’t see the option for daily output (TDAYM), see attached screenshot. How do I add an entry to STASH request? Or am I looking at the wrong variable name for surface pressure?
Cheers,
Wilma
Hi Wilma,
You can modify a STASH specification field by clicking on the specific field and selecting the required value from the menu.
For SURFACE PRESSURE AFTER TIMESTEP, if you click on the T3HR value, you can then select the appropriate fequency (TDAYM is included).
You can do so with any stream (any of your screenshotted STASH requests), or by adding a new one with the New button, and then manually specifying all column fields.
Also remember to tick the first box (Incl) to make sure the STASH is included.
Cheers

Thanks for the advice!
Hi again,
I’ve updated the STASH request list but am running into some issue. The model stops with the below error message. The only variable I have with UP8 is the surface pressure where I changed the output frequency to daily.
What is the use_name? Can I change it?
Many thanks,
Wilma
Hi Wilma,
The use_name is part of the Usage Profiles, it define which “stream” your STASH output is going to be written into.
The additional SURFACE PRESSURE AFTER TIMESTEP you requested has use_name set to UP8, but that Usage Profile is not active by default (if you go to um → namelist → Model Input and Output → STASH Requests and Profiles → Usage Profiles you’ll see there is an exclamation mark before the profile with the associated use_name UP8.
You have 2 main solutions:
You can activate the UP8 profile by right-clicking on the up8 Usage Profile and clicking on “Enable this section”.
This would make the profile available, and your output STASH writing to the UP8 profile will be written according to the UP8 Domain Profile configuration.
You can access this configuration by clicking on the relative profile within the Usage Profiles section ( from the list that expands by clicking on the small arrow button, not directly from the Usage Profile “Main window”).
You can write the requested STASH to another (already active) Profile. To do so, change the use_name assigned to your requested STASH from UP8 to something that is already available (for example UPMEAN).
Note this will place the requested STASH together with the other STASH included within the UPMEAN Profile, which might also already include another SURFACE PRESSURE AFTER TIMESTEP STASH (with a different time domain - tim_name). So, in the output file, you might end up with two fields having the same name, but different time coordinate. For this reason it is is suggested to use different Usage Profiles for different time/spatial domains.
Cheers
