`below_cloud_model.m` returns a struct "profiles" with the arrays listed below. The array sizes depends on the model inputs.
|
|
|
|
|
|
|
|
Variables that describe the profile of ambient air are of size (1xn), where n is the length of the input array "z". "z" defines the grid on which these profiles are defined (background grid).

For example:
|
|
|
|
z: (1x3001) array; p: (1x3001) array
|
|
|
|
|
|
|
|
```
|
|
|
|
z: (1x3001) array; p: (1x3001) array
|
|
|
|
z(305) = 805 m
|
|
|
|
p(305) = 93000 Pa
|
|
|
|
→ The pressure at model level 305 is 930 hPa, which corresponds to 805 m above sea level.

Variables that describe properties of the hydrometeor are arrays of size (1xm), where m is the number of model levels, which are at and below the starting altitude (z_form) of the hydrometeor. The corresponding grid (hydrometeor grid) is defined in "z_out" (and "height")

For example:
|
|
|
|

```
|
|
|
|
z = 0:1:3000 -> (1x3001) array
|
|
|
|
z_form = 2000
|
|
|
|
z_out contains all z<=z_form:
|
|
|
|
z_out = 0:1:2000 -> (1x2001) array
|
|
|
|
m=n if z_form=z(end) (if namelist.z_form=0)
