Celebrating the new year with fireworks is traditional in Italy. A national surveillance system maintained by police indicated that on New Year's Eve 1992, more than 1100 fireworks-related injuries and four deaths occurred in Italy (Ministry of the Interior, unpublished data, 1993). In many areas of the country, the use of fireworks begins several weeks before the new year and continues through...

Abstract. This study proposes an approach to estimate the ocean sea surface height signature of coherent internal tides from a 25-year along-track altimetry record, with single inversion over time, resolving both tide contributions and mesoscale eddy variability. The is performed on reduced-order basis topography practically achieved conjugate gradient. particularity this mitigate potential ali...
