Descriptive statistics of model performance: median aflatoxin.

Dataset	Model performance
	Low (<-4ppb)	Accurate ($\pm 4\mathrm{ppb})$	High (>+4ppb)
Fitting period (2012–2015)	4.7%	83.7%	11.6%
Validation period (2016–2017)	0.0%	85.7%	14.3%
Total period (2012–2017)	3.1%	84.4%	12.5%

Deliveries from the hourly model within each month classified as Low, Accurate, or High if the model predicted median aflatoxin levels is more than 4 ppb below, within 4 ppb of or more than 4 ppb above, respectively, relative to the historical observed median aflatoxin level. The table summarises the proportion of months with each classification for the respective dataset.
