Precipitation data from the Kisumu airport for 2 May 2011 to 4 July 2012. Each point along the x-axis represents one day. The vertical bars show the daily precipitation total. The solid line shows the cumulative 6-day precipitation total (i.e. the level of the line for each day represents the summation of precipitation totals over the previous 6 days), which was used in the logistic regression model of the 10 by 10 km dataset. Similarly, the dashed line shows the daily fluctuation of the cumulative 14-day precipitation total used in the random forest model of the same data. Squares and circles show the days of the ground surveys in the 31 quadrats. Kisumu airport is about 40 km east of Asembo.
