Lake Chad Basin - Analysis of 90 Years Rainfall (Chelsa_Climate model)

Interactive map displaying the Mean Annual Rainfall for the last 9 decades comprised between 1927 and 2016, as well as the Mean Annual Rainfall for the whole period 1927-2016. Source of rough data : Chelsa_Climate model. Click "Read More" to display the map and the technical explanations.

Click on any point of the map to get the Mean Annual Rainfall Value of the last 9 decades as well Mean Annual Rainfall on the total rainfall period 1927-2016. Values are given in mm rainfall.

This map was obtained using the rough data of "Chelsa Model" (CHELSEA_CLIMATE). We have aggregated these data by year and regrouped by period of 10 years. The mean annual rainfall for the whole period 1927-2016 is represented on the map. It has then been clipped to the Basin layer.

CHELSA is a high resolution (30 arc sec) climate data set for the earth land surface areas currently hosted by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL. It includes monthly mean temperature and precipitation patterns for various time periods.
CHELSA is based on a quasi-mechanistical statistical downscaling of reanalysis and global circulation model output and is freely available in the download section.
