HMA_continuity

Scripts to apply the continuity equation in an automated, distributed manner at regional scales, used in 'Health and sustainability of glaciers in High Mountain Asia' by Miles and others.

This is an archive version, note that numerous hard paths have to change for the scripts to be run. Ancillary codes are available on reasonable request. Please also see our user-friendly implementation at: https://github.com/miles916/grid_continuity_SMB
