Tropospheric photochemistry from remote sensing & modeling
HCHO in Alaska is dominated by wildfires in Alaskan summer fire seasons.
Wildfire PM2.5 is overestimated by model, because of underestimated injection height in the model.
PGN shows high potential in evaluating trace gas 4D variability in global scale and hourly temporal resolution.
