Direct measurements of the solar wind speed and the radial component of the interplanetary magnetic field acquired over more than three solar cycles are used to search for signatures of a persistent dependence of solar wind properties on olar longitude. Two methods of analysis are used. One finds the rotation period that maximizes theamplitude of longitudinal variations of both interplanetary a...

Based on the isometric hypothesis, belowground plant biomass (MB) should scale isometrically with aboveground biomass (MA) and the scaling exponent should not vary with environmental factors. We tested this hypothesis using a large forest biomass database collected in China. Allometric scaling functions relating MB and MA were developed for the entire database and for different groups based on ...

The (J,K) = (1,1) metastable ammonia line was searched for in the direction of more than one hundred southern HII regions located between 270◦and 15◦ in galactic longitude, resulting in new detections toward 21 of them. Ammonia detection rate was about 30 % towards all directions except in the longitude interval 270◦–290◦ where no ammonia lines were found in the 15 selected HII regions. A high ...

This technical note describes a method for the rediscretisation of “gridded” geo-scientific data. A recursive algorithm (NREGRID) is derived to solve the rediscretisation problem for orthogonal grids (including curvilinear) of arbitrary dimension. The algorithm is used within the program NCREGRID to handle geo-scientific data. These data are typically 2-dimensional (latitude-longitude grid), or...

The variations of phase and amplitude of a subionospheric transmitted signal at frequency 19.8 kHz from North West Cape, Australia (latitude: 21.82◦S; longitude: 114.16◦E) measured at Kolkata (latitude: 22.56◦N, longitude: 88.5◦E) during the period of solar eclipse (partial, 91.1%) on July 22, 2009 will be presented in this paper. The variations in amplitude are quite significant than the usual...

Unusual single-pulse behaviour has been identified in two pulsars, B0919+06 and B1859+07. Both stars normally emit bright subpulses in a region near the trailing edge of their profile. However, they occasionally undergo ‘events’, whereby the emission longitude gradually decreases by about their profile width, remains in this position for typically several tens of pulses, and then gradually retu...
