HAQAST Sentinel-5P TROPOMI Nitrogen Dioxide (NO2) CONUS Seasonal Level 3 0.01 x 0.01 Degree Gridded Data V2.4 (HAQ_TROPOMI_NO2_CONUS_S_L3) at GES DISC

This product provides level 3 seasonal averages of tropospheric Nitrogen dioxide (NO2) vertical column density derived from the level 2 Tropospheric Monitoring Instrument (TROPOMI) across the Continental United States oversampled to a spatial resolution of 0.01˚ x 0.01˚ (~1 km2) using a consistent algorithm from the European Space Agency (ESA) version 2.4 that can be used for trend analysis of air pollution. The dataset record began in June-August 2018 and continues to the present.本产品为基于美国本土范围内二级对流层监测仪（Tropospheric Monitoring Instrument, TROPOMI）反演数据生成的对流层二氧化氮（NO₂）垂直柱密度三级季节平均产品，采用欧洲空间局（European Space Agency, ESA）2.4版统一算法，将原始数据重采样至0.01°×0.01°（约1平方千米）的空间分辨率，可用于空气污染趋势分析。本数据集的时序记录始于2018年6-8月，至今仍在持续更新。
