Aims • Understanding remote sensing principles and the determination of geophysical parameters from radiation measurements in different spectral regions
• Knowledge of remote sensing instruments and the operational meteorological observation system
• Knowledge of the spatial and spatio-temporal data assimilation methods
Skills• Ability to interpret and to quantitatively analyse remote sensing observations
• Assessment of statistical assumptions, numerical complexities and practical limits of retrieval and assimilation techniques
• Formulation of inverse models and skills to develop adjoint codes
Content • Remote sensing principles, meteorological satellites and orbits
• Passive remote sensing of the atmosphere at visible, infrared and microwave wavelengths for temperature, humidity, clouds & aerosol
• Active remote sensing of the atmosphere with cloud and precipitation radar, lidar, wind profiler, sodar and GPS
• Remote sensing of the ocean (temperature, color, wind, waves)
• Remote sensing of Earth Surface and vegetation (SAR, NDVI)
• Basics of objective analysis and inverse modelling
• Spatial data assimilation (DA) methods: optimal interpolation, 3D-var, minimization methods for data assimilation and preconditioning, multivariate data assimilation
