ARL Celebrates 20th Anniversary of READY

January, 2017

This year marks the 20th Anniversary of ARL’s Real-time Environmental Applications and Display sYstem (READY), a unique, web-based tool that allows users to access and display meteorological data and to run the HYSPLIT dispersion model on ARL’s web server. READY was originally developed for the personal computer but is now easily accessed via a web browser. The system brings together dispersion models, graphical display programs and textual weather forecast programs generated over many years at ARL into a form that is easy to use by anyone.

Over One Million Served!

In 2016, 1,094,305 HYSPLIT simulations were performed on the READY web server, exceeding the previous record of 1,020,081 set in 2014. As the graphic above shows, HYSPLIT simulations have seen a steady increase since 2009 when collecting statistics first began. READY users can create air parcel trajectories or air concentration maps with HYSPLIT using archived or forecast meteorological data, although the primary HYSPLIT simulation has been trajectories using archived meteorological data.
