Dr Inger‐Lise Frogner

Senior scientist at the Norwegian Meteorological Institute, Norway

Profile

Dr Frogner is a senior scientist at the Norwegian Meteorological Institute and has a position in HIRLAM-C management group, where she is project leader for predictability and Ensemble Prediction Systems (EPS) (HIRLAM is a consortium of ten European national meteorological institutes).

She is the head of the group of HIRLAM scientists that do research on predictability and that develop mesoscale ensemble prediction systems. Methods for calibration and verification of EPS are also a part of the responsibility.

Dr Frogner graduated in Meteorology at the University of Oslo (Norway) and did her PhD at the same university, in the field of predictability and ensemble prediction systems. As part of the PhD she worked at ECMWF for six months. She has been involved in developing several ensemble prediction systems, and is currently focused on developing EPS for mesoscale.

Her main research interests are probabilistic forecasting, atmospheric predictability and sensitivity, probabilistic verification and developing systems for prediction of extreme/rare weather events.

Johannes Orphal

Professor Johannes Orphal

Head of Institute of Meteorology and Climate Research (IMK) - Atmospheric Trace Gases and Remote Sensing (ASF), Karlsruhe Institute of Technology, Germany

Profile

Professor Orphal graduated in Physics at Humboldt University (Berlin, Germany) and is Docteur des Sciences (Physique) from Université de Paris-Sud (Orsay, France). He was Chargé de Recherche at CNRS and Professeur (Physique) at Université de Paris-Est (Créteil, France).

Professor Orphal has been involved in the preparation and exploitation of the GOME, SCIAMACHY, MIPAS and IASI satellite experiments. He has proposed new missions and instruments for atmospheric observations on various platforms, including GEOFIS, MAGEAQ, PREMIER, MACE, G3E, and ATMOSAT.

He is also involved in, or co-ordinates, international projects and initiatives concerning air-borne and ground-based measurements of atmospheric composition and dynamics.

Roger Saunders

Dr Roger Saunders

Head of Satellite Applications section, UK Met Office

Profile

Dr Saunders’ section works to improve the use of satellite data for NWP and nowcasting.

During his time at the Met Office, Dr Saunders has worked in the Met Research Flight, where he led the group which made radiation measurements from the C-130 aircraft, and co-ordinated several field campaigns with the aircraft based in the South Atlantic and the Mediterranean to measure water vapour continuum absorption and validate satellite radiometers. He was appointed as the AMSU-B instrument scientist overseeing the pre-launch testing of the radiometer at Farnborough, UK.

Before joining the Met Office, Dr Saunders worked in a number of different institutes, including the Rutherford Appleton Laboratory, the European Space Operations Centre and University College London, in jobs related to the exploitation of meteorological satellite data.

During 1995–1999 he was head of the Satellite Section at ECMWF, with responsibility for making better use of satellite data in the NWP model using the new variational data assimilation techniques. He took the scientific lead in the ongoing development of a fast radiative transfer model, RTTOV, for assimilating satellite radiances. He also provided advice on the use of satellite data in the ERA-40 reanalysis.

Anthony Weaver

Dr Anthony Weaver

Senior Researcher at the European Centre for Research and Advanced Training in Scientific Computation (CERFACS), France

Dr Weaver’s main area of interest has been ocean data assimilation. He has also worked on general algorithmic aspects of variational assimilation and covariance modelling.

He has worked with ECMWF for many years, in recent years giving help and guidance on the NEMOVAR ocean data assimilation system, a collaborative project between ECMWF, the Met Office, CERFACS and INRIA (French National Institute for computer science and applied mathematics).

NEMOVAR is the backbone of ECMWF’s ocean reanalysis ORAS4 and the new ocean reanalysis ORAS5, and is used to initialise the S4 seasonal forecasts and the coupled ensemble forecasts.

Dr Weaver is a member of several international committees and panels as well as a Principal Investigator on a number of European projects.
