Additionally, subtypes Cloud-Aerosol Lidar Infrared Pathfinder (CALIPSO) were used explore...
Developments in mid-infrared Differential Absorption Lidar (DIAL), for gas remote sensing, have received a significant amount of research recent years. In this paper, high repetition rate tunable DIAL, mounted on mobile platform, has been built long range detection plumes. The lidar uses solid-state optical parametric oscillator laser, which can emit laser pulse with 500 Hz and between the band from 2.5 μm to 4 μm. A monitoring channel used record energy real-time correct signals....
Estimating spatiotemporal maps of greenhouse gases (GHGs) is important for understanding climate change and developing mitigation strategies. However, current methods face challenges, including the coarse resolution numerical models, gaps in satellite data, making it essential to improve estimation GHGs.
