Equipped with the GNSS-R, a 300-kg class Triton satellite is developed by NSPOperforms the mission of GNSS sea surface reflection signal researchapplication. Triton satellite collects global navigation satellites’ signals reflected from the surface in low earth orbit,these single data can be used in the research of soil characteristics, air-sea interaction, typhoon intensity prediction etc.

Concerning the uncertainty of assuming well-mixed aerosols within the planetary boundary layer, a sensible aerosol vertical distribution described by a log-normal fitting function is proposed to provide more realistic single-peak extinction profile with a decadal MPL in situ dataset. The performance of fitted single-peak aerosol profiles can reach up 0.8973 of correlation coefficient when considering the seasonal variations in PBLH and the surface layer height of well-mixed aerosols. Eventually, not only the aerosol extinction profile but also the 3-dimensional distribution are promising to be created from satellite AOD retrieval with PBLH information for providing accurate PM2.5 monitoring over a regional scale.
