Workshop on Atmospheric Composition Observation System Simulation Experiments (OSSEs)

The Atmospheric Composition Observation System Simulation Experiments (OSSE) Workshop was held at ECMWF from 22 to 24 October 2012, and was supported by CEOS Atmospheric Composition Constellation, NASA, MACC-II and ECMWF.

Description

Observing System Simulation Experiments (OSSEs) have been extensively used by the numerical weather prediction community in order to help develop and optimize contemporary meteorological satellite instruments. Such numerical experiments are now also increasingly used in other fields of earth observation, in particular for oceanography and atmospheric composition applications.

With the evidence of growing and converging interests for Air Quality monitoring from the geostationary orbit (GEO) in America, Asia and Europe, the Committee on Earth Observation Satellites / Atmospheric Composition Constellation (CEOS/ACC) has recommended to organize a workshop dedicated to study the contribution of future GEO/Air Quality instruments to the global observing system of atmospheric composition using OSSEs.

The specific aims of the meeting hosted by ECMWF on 22-24/10 are:

  • to take stock of the experience from NWP
  • to review existing work worldwide on OSSEs for "chemical" satellite instruments
  • to discuss best practices and to define the needed infrastructure in order to set up reliable OSSEs
  • finally, to define a set of experiments intended to document the impact of GEO instruments (alone, together over different parts of the globe, as well as also in conjunction with Low Earth Orbit instruments). This is of particular relevance in Europe in the context of GMES (Global Monitoring for Environment and Security, GMES (Global Monitoring for Environment and Security) ,and of the setting up of operational air composition services MACC-II.
