  2. Preliminary Visualization study for the MTG – IRS project • Earth • Interferogram MTG-IRS objectives: • • To support regional NWP in Europe, • time • L0 through detailed 3D fields of temperature, humidity, and wind • Detection • • • element at high vertical, horizontal and temporal • L1 processing resolution • To support now-casting and very-short range • Dwell forecasting • L0 • L1 Obviously, a lot of effort is put into development • wave • number of L2 algorithms and products. • Spectral sounding 3D Exploration of Weather Data in Combination with IASI L2 Products M.

  4. Input data for our visualization study: MTG-IRS L2 Proxy (IASI) Data EUMETSAT provided us with: • Point-profiles at ECMWF levels with prior fields (ECMWF) and retrieved fields (IASI L2): • Temperature, specific humidity, and relative humidity • Quality control indicators We have computed derived fields such as Theta-W. Besides pressure information we need geometric height for 3D grid. Note on retrieval algorithm: EUMETSAT implemented the UWPHYSRET algorithm as the IRS Level 2 Development and Validation Processor (IRS-L2DVP). 3D Exploration of Weather Data in Combination with IASI L2 Products M.

  5. Statistics: Important step in understanding • Statistical methods such bias and standard deviation provide a global overview of the numerical quality of the retrievals. • What can be the next step beyond statistics and numerical analysis? bias std. deviation bias std. deviation [KNMI: Siebren de Haan, Gert-Jan Marseille, Paul de Valk] 3D Exploration of Weather Data in Combination with IASI L2 Products M.

  6. Next Step: Visualization and Exploration Our approach: Apply a well-established concept of interactive 3D visualization • of meteorological data that uses Virtual Reality. => Weather 3D Explorer application [KNMI] Provide meteorological context to the IASI retrieval data with actual satellite and • RADAR images, and NWP models such as ECMWF and HARMONIE. Let the forecasters and the scientists interactively explore the weather situation • and study the 3D profile data. 3D Exploration of Weather Data in Combination with IASI L2 Products M.
