The Potential Temperature Editor
The Potential Temperature editor belongs to a type of editors known as family editors which allows related sets of input specifications to be grouped in the same icon editor. The main computation type can be set via the Application parameter which offers these options:
- Potential Temperature - To derive a potential temperature field from temperature data (and lnsp if using model levels)
- Equivalent Potential Temperature - To derive an equivalent potential temperature field from temperature and humidity data (and lnsp if using model levels)
- Saturated Equivalent Potential Temperature - To derive a saturated equivalent potential temperature field from temperature data (and lnsp if using model levels)
There is an additional top level option called Level Type to select the level type:
- Model Levels - Derives the output using model levels. Requires an lnsp field additional to the temperature (and specific humidity) input data.
- Pressure Levels - Derives the output using pressure levels. Requires only the temperature (and specific humidity) input data.
To operate with this icon first you need to select which type of potential temperature field you want to create (parameter Application) then set the type of level of your input (parameter Level Type ). The available parameters will then change in the editor according to your selection.

Please note that in order to use this icon from script (Macro/Python) you ned to use a different function for each top level parameter combination. For model levels the corresponding set of functions are as follows:
while for pressure levels the names are similar but take a different suffix:
