Figure 1.2. Area over which supporting synoptic data will be collected. This domain, appropriate for CASES, was selected for GCIP; data are being collected as part of their ISOP-97 (See Chapter 7 for details).

Figure 2.1. Timing of phases in the diurnal evolution of the ABL, namely Morning Transition which includes the change from stable to convective conditions and rapid growth, Daytime Convective Boundary Layer which includes fairly steady-state conditions, Evening Transition from convective to near-neutral to stable (Also called ABL collapse), Night-Time Evolution which includes development of the low-level jet (several hours after sunset to just after sunrise).
