Description

### What problem does your feature request solve?

Currently the differentiate diagnostic only does Cartesian differentiation. However, working with geospatial data implies we should allow spherical differentiation to occur.

### Describe the solution you'd like

Either an extension of `misc.differentiate` or a new spherical differentiation operator.

### Describe alternatives you've considered

Research direction

Start by locating and reading the existing misc.differentiate diagnostic to understand its Cartesian behavior. Determine whether spherical differentiation belongs there or needs a new operator, then define the expected geospatial behavior and validation needed for the feature to be complete.
