Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Hi, If anyone out there is using the 2D, gradient-based calculations in MetPy (h_convergence, v_vorticity, advection, geostrophic_wind), we're examining switching the expected array order from X,Y to Y,X. The short version is that the current ordering (while conventional mathematically) is hard to get right with almost every gridded data set we can find and you're more likely to get the wrong answer (because it will quietly take data ordered X,Y and give the wrong results); it's also inconsistent with the CF-conventions, as well as matplotlib plotting. For more details, and to offer feedback, see: https://github.com/Unidata/MetPy/issues/389 I'd also love to hear from anyone who is currently using these functions, just to get an idea of their use (and if they're actually being used correctly). This is a likely API change for 0.6 (expected this summer). I also plan to go ahead and put something forward compatible in 0.5.1 (expected in a little over a week).
