Premier Impact study

Premier - Quantification of Atmospheric Pollution and Climate Aspects

IEK-7 coordinates the ESA-funded project "Premier - Quantification of Atmospheric Pollution and Climate Aspects" also referred to as "Premier Impact Study". PREMIER will be the first mission to generate atmospheric trace gas fields at a resolution high enough to study stratosphere-troposphere exchange, tropical convection, the Asian monsoon, pyroconvection, and long-range transport of air pollution (and associated chemical conversions).

Therefore the prime objectives of the "Premier Impact Study" are

  1. to demonstrate the capability of PREMIER to quantify key processes controlling global atmospheric composition in the mid/upper troposphere and lower stratosphere (5-25 km height range), which is a region of particular importance for climate change and
  2. to demonstrate the added value of PREMIER-type observations for validation of chemistry-climate models (CCM) and data assimilation systems used for numerical weather prediction (NWP).

The "Premier Impact Study" led by IEK-7 is carried out in cooperation with eight partner institutes: Centre national de la recherche scientifique (CNRS-GAME and CNRS-LISA), German Aerospace Center (DLR) Oberpfaffenhofen, Environment Canada, Karlsruhe Institute of Technology (KIT), Royal Netherlands Meteorological Institute (KNMI), York University Toronto, and WxPrime corporation (Toronto), together with a group of international scientific experts.
