TROPOMI glyoxal tropospheric columns at S5P-PAL

Glyoxal (CHOCHO) tropospheric vertical columns retrieved from the TROPOMI/S5p instrument. The S5P-PAL data portal provides a continuously updated dataset of L2 glyoxal vertical columns obtained from TROPOMI/S5P. The retrieval method is identical to the one developed in the GLYRETRO project, where a data record of L2 and L3 data covering the period until December 2022 was created. The GLYRETRO (GLYoxal Retrievals from TROPOMI) activity is one of the seven themes from the ESA S5p innovation (S5p+I) project, which aims at further exploiting the capability of the S5p/TROPOMI instrument with the development of a number of new scientific products.本数据集为基于TROPOMI/S5p载荷反演得到的乙二醛（Glyoxal，CHOCHO）对流层垂直柱总量。 S5P-PAL数据门户提供了持续更新的、由TROPOMI/S5p观测获取的L2级乙二醛垂直柱总量数据集。本次反演采用的方法与GLYRETRO项目中开发的方法完全一致，该项目已构建了覆盖至2022年12月的L2级与L3级乙二醛数据记录。 GLYRETRO（全称为“从TROPOMI反演乙二醛”，GLYoxal Retrievals from TROPOMI）项目是欧洲空间局（European Space Agency，ESA）S5p创新（S5p+I）项目下设的七大主题之一，该项目旨在通过开发一系列新型科学产品，进一步挖掘S5p/TROPOMI载荷的应用潜力。
