Initial Request
----------------------------------------------------------------
Hi,
I am wondering if I can use python embedding to read a native (nonstandard)
model grid? Would that be supported by MET and regridding handled
internally?
Thanks,
Liz

Hi Liz,
For clarification, were you thinking about using the python embedding
with
MET's regrid_dataplane with your model grid?

Hi Minna,
I was actually thinking about using python embedding with grid or
point stat.
However, if regrid_dataplane would need to be run as a first step that
is
important to know.
Thanks,
Liz

Hi Liz,
I checked with John to see if what you wanted to do was feasible, and
unfortunately, it is not. According to John, you have some options:
----------------snip--------------
Python embedding is currently supported in MET in 3 ways:
(1) pass a single input 2d field of data along with a definition of
it's
grid
(2) pass a set of lat/lon point observations to ascii2nc
(3) pass a set of matched pairs lines to stat_analysis
With the current functionality, you could technically process all that
data
as being individual points, passing them to ascii2nc, and then passing
the
output to point2grid. But that's horribly inefficient.
Instead, I'd recommend using python to place that collection of
lat/lon
points onto a regular grid. And the easiest would be a lat/lon grid.
And
then the Point-Stat and Grid-Stat tools could use that data as-is...
or it
could regrid to whatever grid she'd like.
-------------------snip---------------
Someone at NCAR has successfully invoked a Python package to perform
regridding to prepare some data for MET. If you wish to pursue the
last
option, I can ask this individual for an example of his methodology.
Regards,
Minna

Thanks! Just to clarify, if the 2D data is on a Gaussian grid or a
reduced
Gaussian grid, can this be handled with python embedding or is the
grid
definition required to be regular lat/lon?

Gaussian grids are supported via python embedding... but it was a very
recent addition. Here's the documentation:
https://dtcenter.github.io/MET/develop/Users_Guide/appendixF.html#python-
embedding-for-2d-data
Search for Gaussian there.
Here's the GitHub issues showing this was added in the met-9.1.1
bugfix
version:
https://github.com/dtcenter/MET/issues/1477
Here's the release notes for that bugfix version:

Gaussian grids are supported via python embedding... but it was a very
recent
addition. Here's the documentation:
https://dtcenter.github.io/MET/develop/Users_Guide/appendixF.html#python-
embedding-for-2d-data
Search for Gaussian there.
Here's the GitHub issues showing this was added in the met-9.1.1
bugfix
version:
https://github.com/dtcenter/MET/issues/1477
Here's the release notes for that bugfix version:
