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.
