Dear ferreters,

I am reading the instruction of @DIN from https://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/variables-xpressions/XPRESSIONS. I noticed that we can use @DIN for the Z-axis for variables like salinity. I am wondering how does @DIN work for the pressure coordinate? How does it give weight to each pressure level? Do I need to flip the pressure levels to use @DIN?

Thank you in advance. 😸
