Map of GNTD Point Locations, Density Reduced to 1 Point Per 100km Grid Cell

Exploration of Temperature and Precipitation in Schistosomiasis-Endemic Regions. There are two sets of climate data samples shown below. The underlying climate data sampled is a 30 year time series (1990-2020) of monthly mean temperature and total precipitation from ERA5. One set represents the whole continent of Africa. These are 14,596 point locations evenly spaced apart in a 50km x 50km grid. ERA5 data was sampled at its native 10km x 10km resolution at each individual point for the entire time series. The second set represents a resampling of the ERA5 data to a 100km x 100km grid, and only grid cells where there was at least one GNTD point location were sampled. This represents 822 points locations.

## Number of GNTD points (thinned) with cor_coef < 0 (Temp. and Precip.): 511
## Number of GNTD points (thinned) with cor_coef < 0.25 (Temp. and Precip.): 666
## Number of GNTD points (thinned) with cor_coef < -0.5 (Temp. and Precip.): 260
