[MITgcm-support] aim.5l_LatLon Topography File Format

[Chris Horvat]

It looks like you are setting your temperature to be 0, but the routine
AIM_DYN2AIM is expecting values in Kelvin (hence the out of range
(100,400)).

Perhaps your initial temperature file or Data/Tref values are set
incorrectly.
