I am trying to uses potential vorticity (PV) as a meteorological tool to isolate Tropospheric airmass from those of stratospheric origin. Many papers discuss calculation of PV as a good technique for this. McIntyre (2012) describe PV as "the constancy on a fluid particle... central to...

Hello, I am trying to calculate the potential vorticity (PV) in units (PVU) of thousands of different parcels of air on varying spatial and temporal scales. Variables available are as follows; parameter Unit Format Precision Default value : 1 date yyyymmdd I8.8 0 99999999 2 time...
