Manaus, BrazilMy general scientific interest is the remote sensing of clouds, particularly from spaceborne sensors. I have been working with the Multiangle Imaging SpectroRadiometer (MISR) ever since its launch in 1998. I was one of the developers of the MISR stereo cloud-motion wind retrieval algorithm, for which I received the NASA MISR Team Group Achievement Award.

My other research area is the interpretation of 1D cloud microphysical retrievals from passive optical and microwave instruments, such as, MODIS and AMSR-E. I use comparative observational studies and Large Eddy Simulations combined with realistic 3D radiative transfer modeling in order to better characterize errors in cloud liquid water path, optical thickness, and effective radius estimates.

I also conducted sun-photometer aerosol optical depth measurements during the Atlantic Ocean transect of the Fall 2010 Polarstern cruise. Last but not least, I occasionally collaborate with my brother, Professor Gábor Horváth, on bio-optical problems and the development of a polarimetric full-sky imager.
