We present a technique for creating a longitude-resolved image of Jupiter’s thermal radio emission. The technique has been applied to VLA data taken on 25 January 1996 at a wavelength of 2 cm. A comparison with infrared data shows a good correlation between radio hot spots and the 5 μm hot spots seen on IRTF images. The brightest spot on the radio image is most likely the hot spot through which...

Alignment of latitude and longitude for all pixels is important for geo-stationary meteorological satellite (GSMS) images. To align landmarks and non-landmarks in the GSMS images, we propose a geometry-based global alignment method. Firstly, the Global Self-consistent, Hierarchical, High-resolution Geography (GSHHG) database and GSMS images are expressed as feature maps by geometric coding. Acc...

OSSE has measured the galactic longitude distribution of both the 511 keV annihilation line radiation and the three-photon positronium continuum within 40 of the center. They have similar shapes, with a composite longitude distribution well represented by an 11 FWHM Gaussian central bulge together with a possible broad disk component comprising as much as 15% of the integral ux between 40 and 3...

On 9 th of March 1500, Portuguese expeditionary team of thirteen ships, after departing Lisbon, discovered Brazil soon on 22 nd of April 1500. Brazil was then called “Terra de Santa Cruz” and was announced a Portuguese colony. As the Portuguese colonists began plundering with the cutting Brazilwood, the word “Brazil” gradually replaced “Terra de Santa Cruz” and became the name of the nation up ...

Currently, most operational forecasting models use latitude–longitude grids, whose convergence of meridians toward the poles limits parallel scaling. Quasi-uniform grids might avoid this limitation. Thuburn et al. and Ringler et al. have developed a method for arbitrarily structured, orthogonal C grids called TRiSK, which has many of the desirable properties of the C grid on latitude–longitude ...

An improved measurement of the composite 0.05 to 10 MeV gamma-ray spectra as a function of longitude from the inner galactic ridge has been made using the Oriented Scintillation Spectrometer Experiment (OSSE) on the Compton Gamma Ray Observatory. The continuum appears to be a composite of 3 independent components. A strong positron annihilation contribution is observed toward the center with an...

Introduction: Jupiter’s Great Red Spot (GRS) is one of its most distinct and enduring features, having been continuously observed since the 1800’s. It currently spans the smallest latitude and longitude size ever recorded. Here we show analyses of 2014 Hubble spectral imaging data to study the color, structure and internal dynamics of this long-live storm. Physical Dimensions: The GRS’s red edg...

Daily data at 16 stations along five latitudes from 13"N. to 33"s. were carefully examined a t the 50-, lo&, and 500-mb. levels for evidence of longitudinal phase progression of the quasi-biennial oscillation (&BO). At 50 mb. there is evidence of west to east progression although there are many irregularities and much uncertainty. The phase dates differ by days a t low latitudes. At 100 and 500...

Long-distance animal migrants often navigate in ways that imply an awareness of both latitude and longitude. Although several species are known to use magnetic cues as a surrogate for latitude, it is not known how any animal perceives longitude. Magnetic parameters appear to be unpromising as longitudinal markers because they typically vary more in a north-south rather than an east-west directi...
