Global Precipitation

Mean precipitation around the world. The brightest green areas average over 24 mm of rain every single day, with the west coast of Colombia and north-east of India ranking among the wettest places on earth. It's interesting to see how the rain outlines the landmasses and how pronounced the equatorial rain belt is.

To create this map I took monthly GPM MHS on NOAA19 (GPROF) Radiometer Precipitation Profiling data between 2009 and 2022. This data can be downloaded via the NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC). The files come in NetCDF format, which I imported into ArcGIS Pro, then combined into a single mosaic raster dataset so that all rasters could be processed together and viewed over time. The final processing step was to use the multidimensional summary statistics tool to calculate the average value for every pixel across the 13 years of data.
