Fig. 3: Cloud properties and organic aerosol mass loading.
From: Significance of the organic aerosol driven climate feedback in the boreal area

a Cloud effective radius and b cloud optical thickness divided based on the level of cloud water path. Data are divided to low (<33rd percentile (1.59 μg m−3), blue) and high (>66th percentile (3.02 μg m−3), red) organic aerosol (OA) mass loadings. The box shows the quartiles of the dataset while the whiskers show the rest of the distribution, except for points that are determined to be “outliers” using a method that is a function of the inter-quartile range. The notch in the box displays the confidence interval around the median. The blue and red numbers above each figure indicate the number of data points in each box.
