Alpine-3D writes SWE to netCDF, but units are off.

[EricKeenan]

netCDF metadata indicate SWE units are meters liquid water equivalent, but values are around 1000. So I guess they are in mm?

Slightly off-topic from the original issue - but I think it would be nice to add the following information to the netCDF files.

• Grid cell area: Computing integrated quantities, i.e. SMB in Gt.

• Lat/Lon in WGS-84: Useful for those not familiar with plotting in different coordinate systems.

Units for SWE correct as of commit c521202.

Great! Closing this issue now.
