[IDV #BFJ-629522]: help with error when using simple difference
- Subject: [IDV #BFJ-629522]: help with error when using simple difference
- Date: Fri, 06 Jan 2017 08:54:42 -0700
Hi Jason,
I'd say you nailed the problem yourself and the IDV gave you an accurate
message: incompatible units.
For starters, you're gonna have to make the vertical coordinate system of these
data compatible if you want to do this calculation.
Best,
