—This paper describes the algorithm for deriving the total column ozone from spectral radiances and irradiances measured by the Ozone Monitoring Instrument (OMI) on the Earth Observing System Aura satellite. The algorithm is based on the differential optical absorption spectroscopy technique. The main characteristics of the algorithm as well as an error(More)
We present measured scattering matrices as functions of the scattering angle in the range 5ø-173 ø and at wavelengths of 441.6 nra and 632.8 nra for seven distinct irregularly shaped mineral aerosol samples with properties representative of mineral aerosols present in the Earth's atmosphere. represent a wide variety of particle size (typical diameters(More)
This paper describes a new ozone column retrieval algorithm and its application to SCIAMACHY measurements. The TOSOMI algorithm is based on the Differential Optical Absorption Spectroscopy (DOAS) technique and implements several improvements over older algorithms. These improvements include aspects like (i) the explicit treat-5 ment of rotational Raman(More)
[1] The cloud pressures determined by three different algorithms, operating on reflectances measured by two spaceborne instruments in the ''A'' train, are compared with each other. The retrieval algorithms are based on absorption in the oxygen A-band near 765 nm, absorption by a collision induced absorption in oxygen near 477 nm, and the filling in of(More)
We have measured the scattering matrix as a function of the scattering angle of randomly oriented particles of a Mg-rich olivine sample and a ground piece of Allende meteorite as cometary analogues using lasers at two wavelengths (442 nm and 633 nm). The elements of the scattering matrix, F ij , depend on the scattering angle, the wavelength of the laser(More)
We present measurements of the scattering angle distribution of the whole scattering matrix for randomly oriented particles of three mineral samples: fly ash, green clay, and red clay at 442 and 633 nm. Fly ash consists of aggregates of nearly spherical particles while green clay and red clay particles represent irregular compact particles. We compare the(More)
[1] We present measurements of the phase function and degree of linear polarization for unpolarized incident light as a function of the scattering angle for El Chichón and Pinatubo volcanic ashes at 633 nm. The results are combined and compared with those for Pinatubo at 442 nm and Lokon volcanic ash at 442 and 633 nm [Volten et al., 2001]. The three(More)
Water managers request maps of water quality parameters such as concentrations of dissolved organic matter, chlorophyll or total suspended matter. Rijkswaterstaat sets up a production chain for such maps using a hyperspectral imaging scanner installed in the Dutch coast guard aircraft. Water quality parameters are retrieved from remote sensed images using(More)
