ECMWF Re-Analysis Project - Model Level Data
Production of a new, validated 15 year data set of assimilated atmospheric data
for the period 12/1978-02/1994
Operational analyses are affected by the major changes in models, analysis technique,
assimilation, and observation usage which are an essential product of research
and progress.
They also can make use only of those observations which become available within
near real time. The ECMWF (European Centre for Medium-Range Weather Forecasts)
performed a consistent re-analysis of atmospheric data using a frozen production
system. The ECMWF Re-Analysis (ERA) Project produced a new, validated 15 year
data set of assimilated data for the period 12/1978-02/1994.
