This icon returns a GRIB field of one of the following : - potential temperature
- equivalent potential temperature
- saturated equivalent potential temperature
Inputs are temperature, logarithm of surface pressure (lnsp) (only if the input data is specified in model levels) and specific humidity (only if calculating equivalent potential temperature). See Holton, 3rd Ed, Appendix D, eq. D-9, for details on the scientific background The generated fields can be simply visualised or saved as GRIB files. | Info |
