You can find part 1 here and part 2 here. In this installment you are bound to find a bit more mathematical stuff. I’m aware that it can be challenging to some, but don’t despair. You won’t need it to understand the results. This stuff is necessary only to communicate what type of computing was necessary to analyze the data (this is the reason the discipline is called computer science after all, we compute things).

Surface Air and Maritime Temperature

B. Analysis from the NOAA’s National Centers for Environmental Information (NCEI) dataset

Again, it was used R Programming to preprocess and summarize the data, with package maps to plot the charts. As the dataset recorded around 139 years, in which not only data gathering techniques changed but also the area covered, missing data was observed. Fortunately, NOAA provided an extended reconstructed sea surface temperature1 that provides a minimum coverage of 60%. To get a better understanding about current Earth’s climate, it was decided to plot the temperature data map for the data available in 2019.
