- geopotential (z) at the surface
- logarithm of surface pressure (lnsp)
- temperature and specific humidity on all the model levels
Output: Geopotential for each level, in m2/s2. To get the height in metres, divide the geopotential by the gravity constant 9.80665 m/s2.
In the procedure below the output data is written in GRIB format.
Note, this procedure is an approximation to the calculation in the IFS, which also takes account of the effects of cloud ice and water and rain and snow.
