Add `UxDataset.integrate()` and `UxDataArray.integrate()` over region #526

Open erogluorhan opened 10 months ago

erogluorhan commented 10 months ago

np.float64 UxDataset.integrate(self, [quadrature_rule, order, Grid region]) that integrates the dataset variables and np.float64 UxDataArray.integrate(self, [quadrature_rule, order, Grid region]) that integrates the data array over a region, if specified.

Note: Existing UxDataset.integrate() and UxDataArray.integrate() integrate over all the faces of the given mesh.

Essentially, much of our integrate and other functionality would remain unchanged, since we would need to implement a way of obtaining a "subset" of our grid.

For example

# global integral 
uxds['v1'].integrate()

# regional integral from a bounding box
uxds['v1'].bound(lon=(-80, 80), lat=(-20,20)).integrate()

# regional integral using nearest neighbors
uxds['v1'].nearest_neighbor(center=(0, 0), r=15).integrate()

Obtaining a subset of our grid while interfacing with our UxDataArray and UxDataset and Grid should be a top priority.

Just an FYI: With this over-a-region functionality, the edge-faces may be expected to change to fit into the region in the newer Grid, so the subsetting implementation in PR #616 may not be sufficient for the ask here (cc @philipc2)

Any new thoughts on this?
