The ECMWF (European Center for Medium range Weather Forecasts) ERA-40 model uses a variational data assimilation system to make a new synthesis of the in-situ and remotely-sensed measurements made worldwide over the period since mid-1957. It produces the basic analysed conventional meteorological wind, temperature and humidity variables as well as stratospheric ozone, ocean-wave and soil conditions. The CSIRO archive contains monthly data for variables concatenated into a single contiguous netcdf file for the time period 1957-2002 with a spatial resolution of 2.5° x 2.5° and has also been further processed to include calculated Anomaly, Climatology and Seasonal forms of this dataset. Trend analysis data is available for specific variables.
