Details about upgrades could be found in Mesinger (2012). The last version of Eta model could be downloaded here.

While the primary use of the model has been for regional weather prediction and NWP type applications (for a review, see Mesinger 2000), the model has been very successful also in regional climate and seasonal prediction applications (e.g., Altshuler et al. 2002, Chou et al. 2005). More recently, a global version (Global Eta Framework - GEF) has been used in researches applications.

The Eta Model is a state-of-the-art atmospheric model used for research and operational purposes. The model is a descendent of the earlier HIBU (Hydrometeorological Institute and Belgrade University) model, developed in the seventies in the former Yugoslavia (the earliest reference being Mesinger and Janjic, 1974).

 

In the eighties, the code has been upgraded to the Arakawa-style horizontal advection scheme of Janjic (1984), then rewritten to use the eta vertical coordinate (Mesinger et al. 1988) (the name of the model derives from the Greek letter (eta - η), and subsequently, at NCEP, supplied with an advanced physics package (Janjic 1990, Mesinger and Lobocki 1991).

It became officially operational at NCEP on 8 June 1993 (Black 1994). In its various versions, the model has been and/or is widely used in numerous countries, including Algeria, Argentina, Belgium, Brazil, Cameroon, China, Costa Rica, Cyprus, Czech Republic, Denmark, Egypt, Finland, Germany, Greece, Iceland, India, Israel, Italy, Malta, Tunisia, Turkey, Peru, Philippines, Serbia and Montenegro, South Africa, Spain, Sweden, and the United States. Details about upgrades could be found in Mesinger (2012).
