Layers include: Tropospheric Nitrogen Dioxide Density monthly median value May 2018 – November 2022. Derived using the eumap package in Python. We derived three standard statistics: (1) 10th percentile (p10), median (m), and 90th percentile (p10). Band info Name Units Scale Description NO2 (µmol m-2) 0.1 tropospheric nitrogen dioxide density Warning: Original data have the different range of latitude among months. In December, there are no data above N 58°, where is approximately between Iceland and Scotland. Therefore, when it comes to monthly aggregation, there is a strip across N 58° as an artifact. It is not suggested to use this dataset in the region above N 58°. For more info about the s5p NO2 product see: https://maps.s5p-pal.com/. Antarctica is not included.
