Filled contours (contourf)

using Makie, GeoMakie, CairoMakie

lons = -180:180
lats = -90:90

-90:90

Create some field of values across lons and lats.

This grid can be of any density, but note that the time it takes to plot scales with the grid size!

field = [exp(cosd(l)) + 3(y/90) for l in lons, y in lats]


fig = Figure()
ax = GeoAxis(fig[1,1])
contourf!(ax, lons, lats, field)
fig
