Change ozone_sonder name

[rschwant]

Change the option for "ozone_sonder" to "ozone_sonde".

• Need to update docs
• Need to update driver
• Need to update examples
• Need to update doc examples
• Maybe grep to make sure found all the places

What about just "sonde"? Or something like "inst_sonde" to emphasize that these data are provided as each profile being just one time and fixed horizontal location

[rschwant]

I like using "sonde" here to make it more general. I put this as the interpolation. Is this right? Are you not interpolating on time here?

Ozonesonde - time and vertical interpolation at a fixed horizontal location

[zmoon]

I believe the model is interpolated to the time of the sonde.

I like using "sonde" here to make it more general.

I like the idea too, I'm not sure if what we currently have there would work with more general sonde data (which might have GPS position and data varying in time for a given sounding). But for that sort of sounding, you might want to use the aircraft option anyway. Has anyone tried that?

[btang1]

when I code the ozone sonder, we interpolate time, that is why we need nearest 2 time step for ozone sonde code.

for vertical interpolation, I use the one in aircraft code.

for horizontal interpolation, no we assume fix lat and lon at starting point.

[rschwant]

Do you interpolate the time to one fixed time for the entire profile or allow the time to vary as the sonde moves along it's trajectory?

[btang1]

I think I interpolated to fixed time, the release time/start time.

[rschwant]

Can you verify this to be sure and if so, I'll update the description so this is clearer to users, thanks!

[btang1]

SURE!

ozone sonder time interpolation based on release time in the observation
code: ds_model = ds_model.interp(time=ds_model.time_obs.squeeze())
p.s. time is release time, only 1 time.

vertical interpolation use aircraft vertical interpolation:
code: paired_data = vert_interp(ds_model,obs.obj,keys+mod_vars)

horizontal interpolation use nearest neighbor, ignore horizontal displacement while sonder flew bottom to top.
code: ds_model = m.util.combinetool.combine_da_to_da(model_obj,new_ds_obs,merge=False)
