Aerosol Indirect Effect and Cloud-base Height Observations in the North East of the United States : Figure 2

Figure 2: The comparison of cloud-base height, cloud effective radius under the different PM2.5 value, the numbers in the bracket stands for the number of points under the different PM2.5 value. (a) cloud-base height VS. cloud effective radius, (b) cloud-base height VS. lifting condensation level.
