High-resolution bromine monoxide satellite data for the Guangdong-Hong Kong-Macao Greater Bay Area (2019)

TROPOMI (TROPOspheric Monitoring Instrument) is a high-precision imaging spectrometer installed on the Sentinel-5P satellite launched by the European Space Agency (ESA) in 2017. TROPOMI data has high spatial resolution (up to 7 km × 3.5 km) and covers the entire world once a day. Based on the 2019 TROPOMI satellite observation data, the BrO Greater Bay Area high-resolution monthly average air concentration was mapped through oversampling and other technologies.
