[cam-users] enquiry for radiation and cloud related study

[Bala Govindasamy]

Hi Anjari Gupta:

1. The Physics calculation in CCM is done every hr. That is supposed to 
be good enough for resolving the daily cycle.
2. SW cloud forcing at the top of the atmosphere can be computed as FSNT 
- FSNTC.
Hope this helps,

Bala.
