Description

Make it possible to specify the target chunks in iris.util.broadcast_to_shape.

This function is often used to broadcast auxiliary coordinate or cell measure data or weights to the same shape as the data from a cube. If the chunks of the broadcasted data do not match that of the cube, this leads to poor computational performance. Rechunking after broadcasting is less efficient, therefore it is really useful to be able to specify the chunks directly as part of the broadcast.

Closes #5456

It looks like the link check is failing because of the use of http:// instead of https://. I opened #5621 to see if I can fix this.
