The possible well being effect of HCHO compared to the lack of international surface moniThe prospective wellness effect of HCHO a improved understanding global surface montoring information demands an effective solution to getcompared to the lack ofof worldwide HCHO suritoring information demands an effective method to get a paper, understanding of we derived the face distribution offered this restricted information. Within this much better as a novel study, international HCHO surface surface concentration of HCHO in 2019 by paper, asTROPOMI VCD data and limglobal distribution offered this restricted data. In this feeding a novel study, we derived the global surface concentration of HCHO ininto aby feeding TROPOMI VCD addition, restricted ited surface HCHO concentration data 2019 neural network model.

Information and Solutions 2. Data and Solutions To estimate the worldwide distribution of HCHO surface concentration, we AAPK-25 custom synthesis utilised two disTo estimate the worldwide distribution of HCHO surface concentration, we used two crete in-situ data sources and Sentinel-5P TROPOMI VCD information around the corresponding lodiscrete in-situ information sources and Sentinel-5P TROPOMI VCD information around the corresponding cation (as shown by the red points in Figure 1) to train our neural network model. We place (as shown by the red points in Figure 1) to train our neural network model. We then applied our model on the international scale and estimated the surface HCHO distribution then applied our model around the global scale and estimated the surface HCHO distribution with self-confidence intervals. with self-confidence intervals.three ofFigure 1.
