TLDR
Read as discussed by the authors is a web-based suite of tools for producing air parcel trajectory and dispersion model results and displaying meteorological data, and it provides a "quasi-operational" portal to run the HYSPLIT atmospheric transport/dispersion model and interpret its results.Abstract:
Air quality forecasters, emergency responders, aviation interests, government agencies, and the atmospheric research community are among those who require access to tools to analyze and predict the transport and dispersion of pollutants in the atmosphere. Because of this need, the unique web-based Real-time Environmental Applications and Display sYstem (READY) has been under continuous development since 1997 to provide access to a suite of tools for producing air parcel trajectory and dispersion model results and displaying meteorological data. READY provides a “quasi-operational” portal to run the HYSPLIT atmospheric transport and dispersion model and interpret its results. Typical user applications include modeling the release of hazardous pollutants and volcanic ash, forest fire and prescribed burn smoke forecasting, poor air quality events, and various climatological studies. In addition, READY provides the user with quick access to meteorological data interpolated to the location of interest, helping in the interpretation of the HYSPLIT model results.read more

Investigation of the behavior of the atmospheric dynamics during occurrences of the ozone hole's secondary effect in southern Brazil
Gabriela Dornelles Bittencourt,Damaris Kirsch Pinheiro,José Valentin Bageston,Hassan Bencherif,Luis Angelo Steffenel,Lucas Vaz Peres +5 more
TL;DR: In this article, the authors analyzed the effect of the Antarctic ozone hole on the mid-latitude regions of Brazil over a 12-year observation period and identified 37 events of influence of the AOH on the southern region of Brazil, where the events showed that in approximately 70 % of the cases they occurred after the passage of frontal systems and/or atmospheric blocks over southern Brazil.

Trajectory optimization for balloon flight planning
TL;DR: In this paper, the authors used a transpacific balloon flight as a test case to evaluate multiple trajectory techniques to select different pathways based upon potential variations in balloon altitudes, which can be used to select optimum flight altitudes based upon forecast meteorological fields.

Estimating vertical diffusion from routine meteorological tower measurements
TL;DR: In this article, data from an instrumented meteorological tower is used to calculate vertical dispersion coefficients and vertical diffusivities using surface layer concepts, which is similar to that at many power plant sites and only a temperature gradient and wind speed are required for the calculations.
