Fig. 3: Aerosol fingerprints on clouds.
From: Substantial cooling effect from aerosol-induced increase in tropical marine cloud cover

Natural experiment of July 2008 with humid condition in the northern part and very dry conditions in the southern part. a–d, The distribution of RH at 850 hPa (a), the response of cloud fraction to aerosol perturbations (b), ACI manifestations for wet conditions (c) and ACI manifestations for dry conditions (d). The boxplots show 10th, 25th, median (Med.), 75th and 90th percentiles with the average indicated by a dot. Cloud droplet number concentration (Nd), cloud droplet effective radius (reff), cloud liquid water path (LWP) and cloud fraction (CF), top of atmosphere upward shortwave flux at all sky (TOA-SWall-sky) and rainfall. All the fingerprint signals pass the Mann–Whitney–Wilcoxom test with significance >95%, unless marked as ‘non-significant’.
