Temperature file for CMIP7 ancillary generation

[StevenHardiman]

Hello,
Since the Met Office climate model runs on geometric height levels, rather than pressure levels, I require a temperature file in order to accurately produce the 3D CMIP7 ozone ancillaries. Is it possible to provide a temperature file that is compatible (i.e. same models and years etc) with the already supplied ozone files, please? If it helps, for CMIP6 this file was zmta_input4MIPs_Temperature_CMIP_UReading-CCMI-1-0_gr_185001-201412.nc.
Many thanks,
Steven

Thanks for reporting. We're doing some updates to nitrogen deposition and new ozone files so hopefully we can include this, but your patience as we work through the to-do list is appreciated!

should we be expecting updates to these datasets soon?

Already done: #379

this is the last thing we need so great if it can be sorted

Hmm ok let's see how quickly we can do this. It's quite late to be finding this out so no promises.

Hi Steven, Sorry for the late reply. I think it should be possible to get some zmta files over the historical time period to you. However, I will need at least another week or so to get this done. The modellers I need to ask for this are currently on holiday.

Hi Michaela. That would be amazing thank you! As Jane says, once we have this file we can generate ozone ancillaries, which are the last to do. An extra week or so is no problem at all :)

Hi @hegglinm, many thanks for producing these files for us - can I please ask for an update on the status of these zmta files ? This is the only forcing dataset we are currently lacking and its preventing us from starting our spin-up. In particular for our high resolution runs which take a long time to run so this is becoming urgent. Great if you can update us on when these will be available and many thanks in advance.

Can the zmta files please be published? ACCESS-NRI also needs these to calculate ozone forcings on hybrid height levels. See ACCESS-NRI/CMIP7-Input#50

Hi all, I have received all the model data this week and need until the end of the week to get them merged, checked and uploaded. Apologies for the delay!

@StevenHardiman @penguian @jmulcahy11 PI and historical zmta files can now be found at https://fz-juelich.sciebo.de/s/6GXCfmMcQsysxng The data will be uploaded to ESGF soon as well. Please let me know if you find anything strange and keep an eye on updates on ESGF.
