DESCRIPTION:HD photoOverviewInterface observations refer to observations t
 hat are sensitive to multiple Earth system components\, including atmosphe
 re\, land\, sea ice\, snow\, and the ocean. They are key for Numerical Wea
 ther Prediction (NWP) and reanalysis. In a coupled data assimilation frame
 work\, used in Earth system approaches\, satellite-sensed interface observ
 ations have the unique potential to simultaneously constrain the various E
 arth system components\, providing consistent initial and boundary conditi
 ons to Earth system prediction models.  Examples of interface observation
 s are window channels from passive microwave or infrared instruments\, sca
 tterometers\, altimeters\, cloud and aerosol-cleared visible observations.
  These observations are currently under-exploited in NWP due to the challe
 nges that constraining simultaneously the atmosphere and the surface (ocea
 n/land) poses. While some of these observations are used in the atmospheri
 c analysis\, information on other Earth System components tends not to be 
 utilised. Assimilation of such observations in a coupled system has the po
 tential to unlock the previously discarded surface information while at th
 e same time improving their use for the atmospheric analysis. Given that f
 ull exploitation of the observing system to improve NWP is at the heart of
  the mission of the EUMETSAT NWP-SAF\, the focus workshop was very relevan
 t to capture recent progress and the state of the art in this area\, ident
 ify key issues and limitations\, and discuss avenues for further developme
 nts. Workshop goalsThe goals of this workshop were to: provide an overvi
 ew of the various interface observations which are available to the NWP co
 mmunity as well as of the forward models which are being developed or are 
 already in use to exploit this type of observations\, assess the state of
  the art on the use of interface observations both in retrievals and in co
 upled data assimilation systems and understand the direction in which the
  scientific community is taking this important and complex problem.  Work
 ing groups discussed the current state of the art and provided recommendat
 ions for future developments. The output of the workshop will be shared wi
 th the community in the form of working group reports\, identifying key re
 commendations for NWP centres. \n\nhttps://events.ecmwf.int/event/420/
