How is height converted to pressure when using hybrid sigma-pressure levels?
Posted: June 23rd, 2020, 8:41 am
My input data is on hybrid sigma-pressure levels, similar to ECMWF (vertical coordinate system flag 4). How is the final column of the trajectory endpoints file, 'PRESSURE', calculated? I would like to be able to plot my source data in either height or pressure coordinates, but I want to make sure the conversion I'm using on my data matches that used in the trajectories so that they line up correctly.
