This guide provides an overview of seasonal analysis concerning atmospheric CO2 concentrations, specifically from Mauna Loa. It includes R code to plot CO2 data with customized visual elements such as grid lines for yearly and decadal intervals. The plot illustrates CO2 levels in parts per million (ppm) over several decades, showcasing trends and fluctuations over time. By applying differencing techniques, we can better understand the seasonal patterns and long-term trends in carbon dioxide levels.
