    Notes: Abstract The current status of scanning probe microscopy on superconductors is briefly reviewed. Both tunneling and force microscopy have clearly become valuable tools for topographic surface characterization of superconductors. They have especially contributed to our understanding of growth mechanisms, morphology and surface properties of high-temperature superconductors. Furthermore, scanning tunneling spectroscopy on some special model-type conventional superconductors has provided completely new insight into fundamentals of superconductivity. In the latter respect only moderate success has yet been met for all technically relevant materials and especially for the ceramic materials due to surface quality problems. Very recent results show that magnetic force microscopy may be capable of imaging flux lines in superconductors, even if the surface is non-ideal. Flux-line imaging has already been achieved by employing scanning field probes. Some concrete future challenges concerning the application of scanning probe techniques to the study of superconducting materials and superconductivity are discussed.

    Description: Prelaunch and postlaunch calibration results for the Meteor 3/total ozone mapping spectrometer (TOMS) instrument are presented here. Ozone amounts are retrieved from measurements of Earth albedo in the 312- to 380-nm range. The accuracy of albedo measurements is primarily tied to knowledge of the reflective properties of diffusers used in the calibrations and to the instrument's wavelength selection. These and other important prelaunch calibrations are presented. Their estimated accuracies are within the bounds necessary to determine column ozone to better than 1%. However, postlaunch validation results indicate some prelaunch calibration uncertainties may be larger than originally estimated. Instrument calibrations have been maintained postlaunch to within a corresponding 1% error in retrieved ozone. Onboard calibrations, including wavelength monitoring and a three-diffuser solar measurement system, are described and specific results are presented. Other issues, such as the effects of orbital precession on calibration and recent chopper wheel malfunctions, are also discussed.

    Description: The design of the vector magnetometer selected for analysis is capable of exceeding the required accuracy of 5 gamma per vector field component. The principal elements that assure this performance level are very low power dissipation triaxial feedback coils surrounding ring core flux-gates and temperature control of the critical components of two-loop feedback electronics. An analysis of the calibration problem points to the need for improved test facilities.
