Input data for "Transformative 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.<br>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&lt;0151:TGOMEG&gt;2.0.CO;2] and SCIAMACHY [http://dx.doi.org/10.1175/1520-0469(1999)056&lt;0127:SMOAMM&gt;2.0.CO;2] satellite observations acquired between 2000–2002 and 2003–2009 [https://doi.org/10.1038/nature040927l], respectively.

北京地区DSM_QSCAT数据集为基于城市基础设施的年度观测数据，空间格网分辨率约1公里。该数据集通过对L1B级Ku波段QuikSCAT卫星数据应用密集采样法（Dense Sampling Method）生成，相关卫星数据由SeaWinds散射计于1999年7月19日至2009年11月22日持续采集，相关卫星数据集可参考https://podaac.jpl.nasa.gov/dataset/QSCAT_LEVEL_1B_V2，密集采样法的相关文献可访问https://doi.org/10.1007/978-0-387-36699-9。
北京地区GOME_SCI数据集表征年均对流层NO₂柱浓度，空间格网分辨率约14公里。该数据集分别源自2000-2002年的GOME卫星观测与2003-2009年的SCIAMACHY卫星观测，相关文献分别可参考http://dx.doi.org/10.1175/1520-0469(1999)056&lt;0151:TGOMEG&gt;2.0.CO;2与http://dx.doi.org/10.1175/1520-0469(1999)056&lt;0127:SMOAMM&gt;2.0.CO;2，相关联合研究文献可访问https://doi.org/10.1038/nature040927l。
