Monitoring Atmospheric Composition and Climate – Interim
Implementation
MACC-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
ERA-CLIM: A 3-year FP7 project coordinated by
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

Reanalyses
provide a complete picture
of recent trends
example: temperature
Deg 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
