Monitoring Atmospheric Composition and Climate – InterimImplementationMACC-II is the third in a series of FP6 & 7 EU projects (since 2005). It is coordinated by ECMWF and the consortium comprises 36 partners from 13 countries. It runs till July 2014, when GMES operations are expected to start.

MACC-II global system relies on ECMWF variational 4d-var scheme, assimilating a range of remote-sensing data to deliver analyses (illustrated here for Carbon Monoxide, a tracer of combustion sources).

… to global forecasting…

MACC-II provides daily 5-day global forecasts with a horizontal resolution of 80 km and a time resolution of 3 hours, using a “chemistry-enabled” version of ECMWF’s forecast model.

Climate monitoring by reanalysis

Re-analysis of the recent past: Global datasets for monitoring climate change

ERA-15 ERA-40 ERA-Interim ERA-20C

ERA-40: 6-hourly gridded data products from 1957-2002

ERA-Interim: From 1979 to present, monthly updates near real-time

ERA-CLIM: A 3-year FP7 project• Preparing a new atmospheric reanalysis of the 20th Century • Contributes to the GEO 2012-2015 work plan:

CL-01 C1 Extension and Improvement of the Climate Record

Slide 12 © ECMWF

To prepare input observations, model data, and data assimilation systems for a new atmospheric reanalysis of the 20th century

ERA-CLIM will deliver: • Data rescue (both in-situ and satellite)• New reanalysis products• Improved data quality• Improved data access

ERA-CLIM: A 3-year FP7 project coordinated by ECMWF

Reanalyses

provide a complete picture of recent trends example: temperatureDeg C/decade, 1979-2001

Summary

●Reanalysis of in-situ observations and satellite data produces a complete, comprehensive and coherent record of the recent climate

●Increased confidence in climate change science and models’ ability to reproduce the climate of the twentieth century

●Sectors to benefit include: health, industry, water, climate, weather, ecosystems, agriculture, biodiversity and disaster mitigation
