Abstract: We present results of an exploratory study to use near-infrared integral field spectroscopy to observe extrasolar planets. Our concept was tested with a K-Band time series observations of HD209458b and HD189733b obtained with SINFONI at the VLT and OSIRIS at Keck during secondary transits at a spectral resolution of R=3000. In this article we focus on the specific problems of ground-based, high signal-to-noise observations and demonstrate possible solutions for spetral timeseries. An advanced reduction method using elements of a spectral-differential decorrelation is discussed.
