High Spatial Resolution CO2 Measurement Using Low-cost Commercial Sensors in Seoul Megacity

We interpolated the (corrected) Bongcheon Intersection measurement data from HT-2000 meters 2-dimensionally using scatteredinterpolant function in Matlab, which uses Delaunay triangulation. This was performed for each timestep, then plotted on the map of the region. The resulting .png files were then made into .mp4 movies using FFMPEG, resulting in supplement videos S1-S4.
