The Ozone Monitoring Instrument (OMI) is a UV/VISible spectrograph (270-500 nm). It employs two-dimensional arrays of CCD detectors for simultaneous registration of numerous spectra from ground pixels in the swath perpendicular to the flight direction. As a result, OMI provides (almost) daily global coverage in combination with small ground pixel sizes(More)
a r t i c l e i n f o Keywords: Bismuth Template stripping Surface roughness Crystal structure Young's modulus In this paper we present a method to deposit thin films of bismuth with sub-nanometer surface roughness for application to diamagnetic levitation. Evaporated films of bismuth have a high surface roughness with peak to peak values in excess of 100(More)
— This paper describes our work to magnetically steer self-propelled devices which move by catalysis of hydrogen peroxide. We demonstrate manipulation of paramagnetic particles with a diameter of 100 µm to a given setpoint by means of magnetic field gradients, as well as self-propelled movement of gold-platinum rods. We discuss how to reach magnetic torque(More)

Wind scatterometry is an important technique for retrieving high-resolution near-surface wind information in ocean areas where other techniques provide sparse coverage. Scatterometer winds are principally ambiguous in wind direction. In this paper a variational method for ambiguity removal, named 2DVAR, is presented. 2DVAR performs an incremental analysis(More)
The ERS-1 and ERS-2 play an essential role in the development of the Ocean and Sea Ice Satellite Application Facility (OSI SAF), to become an integral part of the satellite ground segment. During the life time of ERS-1 and ERS-2 the processing of ERS scatterometer winds has been developed considerably, and many operational centers using scatterometer data(More)
