I'm looking at some of the new GOES-16 derived products being distributed via
NOAAport and I have a question. Looking at the ABI L2+ Derived Stability
Indices: Lifted Index products, I am seeing the temperatures given with
units="K" (Kelvin), but some of the data values are in the negative range.
Because lifted index is given as a temperature difference, I believe that the
units field of the data is being incorrectly populated and should probably be
"C". Is anyone else seeing this?
Is there somebody I can contact about this issue?
