The air quality in the urban region varies based on sources of pollution from regions near and far. Any produced affects locality source also adjacent distant regions. study interaction between local weather patterns a pollutants is needed for management. It explicit that Chennai city has high level pollution. But unavailability relevant data makes management difficult. If known, it will be hel...

The National Oceanic and Atmospheric Administration (NOAA) produces a daily satellite based smoke and fire analysis for the US. The capability to specify smoke concentration levels and to identify the start time, duration and areal extent of a particular fire which is producing smoke emissions has recently been added. Smoke concentration values are obtained from visual inspection of animated Ge...

Using the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model to obtain backward trajectories and then conduct clustering analysis is a common method analyze potential sources transmission paths of atmospheric particulate pollutants. Taking Qingdao (N36 E120) as an example, global data assimilation system (GDAS 1°) days from 2015 2018 provided by National Centers for Environ...

Cucumber downy mildew is a typical fungal airborne disease in which pathogenic spores are transmitted remotely by air currents, resulting regional endemics. It of great significance to study and analyze the temporal spatial changes spores, especially trajectory sedimentation concentration propagating with airflow air, for prediction cucumbers. Therefore, based on GDAS meteorological data from O...
