ECMWF/GEO Workshop on Atmospheric Re-analysis

The ECMWF/GEO Workshop on Atmospheric Reanalyses was held from 19 to 22 June 2006.

Description

The workshop considered the status of and plans for global reanalysis in Europe, Japan and North America, and will identify the work needed to prepare for the new generation of multi-decadal global reanalyses to succeed ERA-40, JRA-25 and the NCEP reanalyses. Conclusions of recent workshops covering observational aspects (the ECMWF workshop on bias-correction of satellite data, and others held elsewhere) were reviewed, and specific consideration was given to complementary aspects of data-assimilation development and to key user requirements. The scope for coordination of international reanalysis activities was examined.

A discussion session covered the following topics:

  • User needs for reanalysis
  • Observation datasets and boundary forcing fields
  • Homogenization of data
  • Requirements for the data assimilation system
