Reanalysis of the Tropospheric Chemical Composition over the past 40 years

Project Description
The RETRO project aims at a better exploitation of existing observational data sets of chemical trace compound concentrations by performing a 40 years reanalysis of the tropospheric chemical composition. It will for the first time collect and analyse a multitude of observational data from earth-, air-, and spaceborne instruments and evaluate all of them in a consistent manner by performing multi-decadal simulations with several comprehensive global state-of the-art models.
