understanding pyresample to regrid irregular grid data to a regular grid
I need to regrid data on a irregular grid (lambert conical) to a regular grid. I think pyresample is my best bet. Infact my original lat,lon are not 1D (which seems to be needed to use basemap.interp or scipy.interpolate.griddata).
I found this SO's…

Plotting Sentinel-3 Scene with cartopy
I'm following along the Pyresample example for plotting a Sentinel-3 Scene along with coastline. However, it seems as if pyresample.kd_tree.resample_nearest and pyresample.save_quicklook expect a 2D array as data, rather than the 3D (3-band)…

While it's possible to make a map plot by either:
crs = area_def.to_cartopy_crs()
ax = plt.axes(projection=crs)
ax.background_img(name='BM')
plt.imshow(result, transform=crs, extent=crs.bounds, origin='upper', cmap='RdBu_r')
