How to run tobac with my own 2D data

[zhangzh1118]

Hey, I am using the output data from A two-dimensional (x-z) slab-symmetric cloud model, which has a vertical and horizontal resolution of 300m and 100m respectively. The grids of the model does not have a corresponding latitude and longitude.

I want to detect clouds using a constraint that the drop mixing ratio is greater than 0.01 kg/kg in the vertical profile plot.

I have the data in txt files and want to write them into nc files to run tobac. l would like to ask which variables in nc files are necessary for tobac to run. thank you for your time to read my question!

You should be able to get tobac to track clouds in any dataset that you can put into Iris (https://scitools-iris.readthedocs.io/en/latest/) format. I recommend loading your data into an xarray (https://docs.xarray.dev/en/stable/) DataArray first, then converting that to Iris. tobac doesn't require any variables to be present other than time.

You will run into issues with tracking; tobac does not currently have support for tracking with unequal grid spacing; it will need to assume that your grid is equally spaced.

@zhangzh1118 did you end up deciding to use tobac? If so, has it worked for you?
