Grid/PFT variable to lat lon variable conversion

[mm3975]

To test a hypothesis, we want to use the University of Texas coupled high and low-resolution outputs for ET. They have saved the ET as column variables (maybe at grid level). Can anyone help us convert the column variables into lat lon variables? Is there a script or function to process column data? You may find the metadata details below:

@mm3975 sorry for the very long delay responding to this issue! We have a couple of recent ESDS blog posts that cover working with unstructured model output (i.e., column level) and remapping to latitude x longitude. Hopefully these might help:
