Input data for "Transformative Urban Changes of Beijing in the Decade of the 2000s"

The DSM_QSCAT_data for Beijing, representing annual infrastructure-based urban observations at a posting of ~1 km, are obtained by applying the Dense Sampling Method [https://doi.org/10.1007/978-0-387-36699-9] to Level L1B Ku-Band QuikSCAT satellite data [https://podaac.jpl.nasa.gov/dataset/QSCAT_LEVEL_1B_V2] which were continuously collected between July 19th, 1999 and November 22nd, 2009 by the SeaWinds scatterometer.
The GOME_SCI_data for Beijing, representing tropospheric NO2 column densities averaged annually and posted approximately 14 km, are derived from GOME [http://dx.doi.org/10.1175/1520-0469(1999)056<0151:TGOMEG>2.0.CO;2] and SCIAMACHY [http://dx.doi.org/10.1175/1520-0469(1999)056<0127:SMOAMM>2.0.CO;2] satellite observations acquired between 2000–2002 and 2003–2009 [https://doi.org/10.1038/nature040927l], respectively.
Figure S1 allows to visually compare annual DSM-based urban area extents against the corresponding intercalibrated stable night light data [https://doi.org/10.1109/TGRS.2016.2572724] for each year in the 2000s.
