Aksel C. Wiin-Nielsen (17 February 1924 – 26 April 2010) was a Danish professor of meteorology at University of Copenhagen, University of Michigan, Director of the ECMWF, and Secretary-General of WMO.
Major deployments have been for network-intensive and memory-intensive applications (as opposed to FLOPS-intensive), such as weather & climate modeling (ECMWF, UKMO, Environment Canada, Japan Meteorological Agency), and scientific research (University of Warsaw, Slovak Academy of Sciences, and several other government laboratories in the U.S., and other countries).
