Hello,does pyart have the function of mapping two radars' Composite Reflectivity?

@lsxlv Hello! We are currently in the process of getting a composite reflectivity function within Py-ART, once that's in. I believe if you have both radars with the generated composite field, you should be able to map both radars to the map_radars_to_grid function to map them both.

@zssherman Thanks for answer! I have drawn the base reflectivity mosaic of the two radars with 'map_to_grid' function. This function is really good.
You mean that if I can draw the composite reflectivity of two radars on Cartesian coordinate seperately, then I can use 'map_to_grid' function to map these two composite reflectivity together ？

@lsxlv you can pass multiple radars to the pyart.map.grid_from_radars function, for example:

gridded_radar = pyart.map.grid_from_radars((radar1, radar2), grid_shape, grid_limits))

see the docs here grid_from_radars docs

We use this workflow one of the examples grid from radars example

@lsxlv For that you want to use GridMapDisplay, but the syntax for cartopy is the same for it

[lsxlv]

So I should use function'pyart.graph.GridMapDisplay.plot_grid'?

@lsxlv Yep! then you can specify the field and the level at which to plot.

@zssherman Thank you ! I'll try it

[zssherman]

No problem!

@lsxlv - we merged a pull request this morning adding this new functionality, thanks to @dopplerchase !

Link to the example in our gallery

We are working on releasing a new version, which include this!

Great! Excellent！Thank you very much!
