Sažetak
The manuscript Svensmark et al (2012), hereafter referred to as SES12, continues the work begun in an earlier study by Svensmark et al. (2009), in an attempt to analyze the effects of Forbush Decrease (FD) events on cloud properties. The authors have focused on cloud parameters from the Moderate Resolution Imaging Spectroradiometer (MODIS) dataset, claiming that significant changes in a range of globally averaged MODIS cloud properties support the hypothesized link between changes in the galactic cosmic ray (GCR) flux and cloud cover. After a detailed and careful analysis of the MODIS cloud fraction data we find that the results presented in SES12 are statistically insignificant and their conclusions are unsupported by the data. We attribute the author’s significant results to a poor statistical handling of the data, and consequently recommend rejection of this work.
