Forecast runs: EPIC 2001 stratocumulus study
EPIC observations- Oct 16-21, 2001- WHO buoy: 20S-85W
Forecast runs- CAM 26L- CAM 60L- CAM-UW 30L- CAM-UW 60L
- Resolution: T42- Timestep:20 min (26/30L)
10 min (60L)
WHO Buoy
Vertical resolution: 26, 30, 60 levels
Standard CAM UW-CAM 60 levels
Column state: observations versus ERA40
ERA40: PBL too shallow, too cold and too wet
Other candidates to initialize the column state
