progcld3 General Algorithm

1. Find top pressure (ptopc) for each cloud domain for given latitude.
2. Calculate liquid/ice condensate path in \( g/m^2 \)
3. Calculate effective liquid cloud droplet radius over land.
4. Calculate layer cloud fraction.
5. Calculate effective ice cloud droplet radius following Heymsfield and McFarquhar (1996) [82].
6. Call gethml() to compute low,mid,high,total, and boundary layer cloud fractions and clouds top/bottom layer indices for low, mid, and high clouds.
