  1. N fields: number of oil palm fields for which we have data; median elevation: extracted from elevation data at 30 arc-second resolution, aggregated from the Shuttle Radar Topography Mission 90 m-resolution data (Jarvis et al. 2008); median annual yield: median total annual yield for all fields at a plantation, for years for which we had data for all months in an oil palm field; median palm age: median age of oil palm for all yield datapoints included in annual yield values; % yield in peak month: mean percentage of the annual yield which is harvested in the peak yield month; monthly Tmax, Tmin and rainfall: mean and range (minimum–maximum) of all values at the timepoints of oil palm yield data for that plantation
