OBSTAT documention
4 June 2008, by Paul PoliThis documentation was written by Paul Poli in April 2006 and is regularly updated since then.
Abstract The OBSTAT software computes and plots statistics on observations assimilated in the ECMWF or Meteo France assimilation suite. One common application of OBSTAT is to produce statistics of observation minus background and observation minus analysis quantities. One assimilation time period is sufficient to run OBSTAT, but statistics over several assimilation time periods can be cumulated (...)
