Seasonality
site_file$seasonality$monthly_rainfall
Monthly rainfall estimates
Variables
month Month integer
month_name Month
t Midpoint of month
rainfall Monthly rainfall estimate (mm)
Description
Monthly rainfall global rasters aggregated to the site by taking the
population at risk weighted mean rainfall across the region.

site_file$seasonality$seasonality_parameters
Fitted Fourier series seasonality parameters
Variables
g0, g1, g2, g3, h1, h2, h3 Fitted Fourier seasonality
parameters
Description
For each site we estimate the Fourier series parameters representing
general seasonal profiles using the umbrella R package.
site_file$seasonality$fourier_prediction
A prediction of the seasonal curve using the estimated parameters
Variables
t Day of the year
profile Fourier estimate
Description
We do not currently include historical year-on-year variability in
rainfall seasonality into the model runs so Fourier seasonal curves
represent an average over all historical years in the rainfall
dataset.
site_file$seasonality$peak_season
Peak rainfall day
Variables
peak_season Day of the year with peak rainfall (from
fitted fourier)
Description
Peak rainfall season is used to estimate timing of seasonally
targeted interventions such as SMC and IRS.
