Initial Request
----------------------------------------------------------------
Dear MET Helpdesk,
I'm working with a dataset on rotated lat/lon projection, or rotated pole
projection. I looked through the website
http://www.dtcenter.org/community-code/model-evaluation-tools-met/sample-analysis-scripts,
and did not find a sample script (read_xxx.py) for the rotated lat/lon
projection. I do not know how to set the attributes. For example, what are the
variables I should provide in the attribute section? Below is an example for
the Lambert Conformal projection.
'grid': { 'type' : "Lambert Conformal", 'name' : "WRF Domain", 'hemisphere' :
'N', 'scale_lat_1' : 26.8, 'scale_lat_2' : 26.8, 'lat_pin' : 26.8, 'lon_pin' :
111.722, 'x_pin' : 436.0, 'y_pin' : 329.0, 'lon_orient' : 111.722, 'd_km' :
3.0, 'r_km' : 6371.2, 'nx' : 873, 'ny' : 659, } The rotated lat/lon projection
I'm working with is like this:
gridtype = lonlatgridsize = 216000xname = rlonxlongname = longitude in rotated
pole gridxunits = degreesyname = rlatylongname = latitude in rotated pole gridyunits
= degreesxsize = 500ysize = 432xnpole = 310ynpole = 70xfirst = 342.9797xinc =
0.04050001yfirst = 0yinc = 0.0405
Do you have a sample python script for the rotated lat/lon projection? Or could
you tell me what are the variables I should provide in the attributes and what
their meanings are?
Thank you very much!!!
Sincerely,Yuxing

Hi Yuxing,
The following is an example script that uses a LatLon projection:
http://www.dtcenter.org/sites/default/files/community-code/met/python-
scripts/read_CPC_binary.py.txt
The grid information you enter in the attrs dictionary should match
this
format:
'grid': {
'name': 'Global 1 Degree',
'type' : 'LatLon',
'lat_ll' : -90.0,
'lon_ll' : -180.0,
'delta_lat' : 1.0,
'delta_lon' : 1.0,
'Nlat' : 181,
'Nlon' : 360,
}
More information about the supported projections and the values to set
can
be found here:
https://dtcenter.github.io/MET/latest/Users_Guide/data_io.html#met-
configuration-file-options
(scroll down to the section that describes the 'regrid' dictionary).
If the data is rotated, you will need to ensure that you transform
your
data so that it is oriented in the correct way. A good method to check
that
the data is mapped properly is to use the plot_data_plane MET tool.
Here is
a sample command that uses a python script to read in the data:
plot_data_plane PYTHON_NUMPY out.ps 'name="/path/to/python/script.py
arg1
arg2";'
This will generate a postscript file called out.ps that you can view
(or
convert to an image file) to verify that the data is mapped correctly.
You
will need to verify that the country border lines are in the correct
locations relative to the data. If they are, then the data is ready to
be
read into the other MET tools.
Please let me know if you have any other questions.
Thanks,
George

Hi Yuxing,
I apologize for giving you incorrect information. It turns out rotated
lat/lon projections are indeed supported directly by the MET tools.
Support
for this was added relatively recently, but the documentation was not
updated to include information on configuring the tools to read these
data.
Another developer is currently working on obtaining the names of the
necessary variables to set and updating the documentation. I will
respond
to this ticket when I learn what you need to set. Thank you for
discovering
that this information is missing from the documentation!

From: George McCabe
Time: Thu Nov 19 13:31:11 2020
Hi Yuxing,
Here is the information you will need to set for a rotated lat/lon
grid.
- *Rotated LatLon* grid dictionary entries:
- type ("Rotated LatLon")
- name (string)
- rot_lat_ll, rot_lon_ll (double)
- delta_rot_lat, delta_rot_lon (double)
- Nlat, Nlon (int)
- true_lat_south_pole, true_lon_south_pole (double)
- aux_rotation (double)
It looks like in addition to the grid dictionary items that are
required
for a lat/lon projection, you will also need to set
true_lat_south_pole,
true_lon_south_pole, and aux_rotation. Please let me know if you run
into
any issues getting this set up.
Thanks,
George
