The National Centers for Environmental Prediction (NCEP) Aviation (AVN) global gridded analysis datasets for the period from Jan 2002 until the current day. The NCEP AVN gives 6 hourly Atmospheric variables at 26 levels with a resolution of 1 degree. It is a time limited model run produced to give global weather forecast predictions for other clients that rely on data being available at a fixed time, especially important for applications such as aviation. The AVN model was superceeded in October 2002 and is now known as the global forecast system (GFS)model, however as other software and systems rely on this folder naming convention {avnYYMM (YY=year, MM=month)} the newer GFS model data is still being saved with this older title. This archive is updated daily.
