Correspondence between 60 and 91 model level definitions

Correspondence between the L60 and L91 model levels showing the values of full level pressure, p_L60 and p_L91, respectively, for a surface pressure of PS[hPa]= 1013.250.

A description of how model levels should be interpreted is available in the IFS documentation Part III- chapter 2 (DISCRETISATION --> Vertical discretisation)
