A Rainy Reputation by Christopher Ahmed

Washington state has a rainy reputation. But let's put that to the test. This visualization uses precipitation data from over 100 weather collection stations for the year 2020 (~30k points), which were then interpolated with kriging (~120k points), and enhanced with data densification (~1.2million points) to create a map that shows where, and how intense precipitation was experienced across time and place in the state of Washington. In addition to showing rain, ground cover splotches, as if they are puddles of natural sustenance, are slightly highlighted. Their intensity is based on how much precipitation was experience in the past few days. Tools used: R, Tableau, PowerPoint, Excel. Data sources: NOAA (National Oceanic and Atmospheric Association) and the National Weather Service Cooperative Observer Program (COOP).
