  1. Cloud Cover/Visibility was coded as Variedsystematic if it was recorded at regular intervals throughout the study period. It was coded as Variedevents only if it was only recorded during aggregation/mortality events and Varieddescriptive if authors described in general terms the conditions under which aggregation/mortality were most likely to occur
