Schematics representing the timeline of GAIA quasi-realtime and forecast simulations. GAIA run on each day consists of 1-day simulation (blue thick arrow) including the meteorological data JRA and 4-day simulation without JRA input (light blue thick arrow). The WJRA calculation on the current day (middle ribbon) uses the final condition of the WJRA (with JRA) calculation on 1-day prior (top ribbon) as an initial condition. SWx denotes space weather, and UT denotes universal time. The simulation launch time following a data download is shown by filled stars. See details in the text
