    High-resolution photoabsorption cross section measurements of SO<inf>2</inf>, 2: 220 to 325 nm at 295 K

    , Journal of Geophysical Research: Planets, Vol: 108, ISSN: 0148-0227

    High-resolution, ultraviolet SO2 photoabsorption cross section data are required for modeling density and temperature profiles of SO2 in solar system atmospheres. We report measurements of such cross sections on SO2 at 295 K for the B1B1 - X1A1 and C1B2 - X1A1 bands over the wavelength range 220 to 325 nm. Resolving powers of up to 550,000 were employed in order to study the congested spectrum of sharp SO2 features in parts of this region. Our data are compared to earlier values obtained with lower resolving power.

    The effects of solar variability on the Earth's climate

    , Meeting on Science and Applications of the Space Environment: New Results and Interdisciplinary Connections, Pages: 95-111

    The absolute value of total solar irradiance is not known to better than ca. 0.3% but measurements from satellite instruments over the past two solar cycles have shown that it varies by ca. 0.1% on this time-scale. Over longer periods its value has been reconstructed using proxy measures of solar activity, and these suggest that during the Maunder minimum in solar activity of the late 17th century it was 3-4 W m(-2) lower than at present. Observational data suggest that the Sun has influenced temperatures on decadal, centennial and millennial time-scales, but radiative forcing considerations and the results of energy-balance models and general circulation models suggest that the warming during the latter part of the 20th century cannot be ascribed entirely to solar effects. However, chemical and dynamical processes in the middle atmosphere may act to amplify the solar impact. An analysis of zonal mean temperature data shows that solar effects may be differentiated from those associated with other factors such as volcanic eruptions and the El Nino Southern Oscillation.

    Density-transition scale at quasiperpendicular collisionless shocks

    , Physical Review Letters, Vol: 91, ISSN: 0031-9007

    Measurements of a spacecraft floating potential, on the four Cluster spacecraft, are used as a proxy for electron plasma density to study, for the first time, the macroscopic density transition scale at 98 crossings of the quasiperpendicular terrestrial bow shock. A timing analysis gives shock speeds and normals; the shock speed is used to convert the temporal measurement to a spatial one. A hyperbolic tangent function is fitted to each density transition, which captures the main shock transition, but not overshoot or undershoot nor foot features. We find that, at a low Mach number [Formula presented], the density transition is consistent with both ion inertial scales [Formula presented] and convected gyroradii [Formula presented], while at [Formula presented] only the convected gyroradius is the preferred scale for the shock density transition and takes the value [Formula presented]. © 2003 The American Physical Society.

    Multi-scale magnetic field intermittence in the plasma sheet

    , Annales Geophysicae, Vol: 21, Pages: 1955-1964, ISSN: 0992-7689

    This paper demonstrates that intermittent magnetic field fluctuations in the plasma sheet exhibit transitory, localized, and multi-scale features. We propose a multifractal-based algorithm, which quantifies intermittence on the basis of the statistical distribution of the "strength of burstiness", estimated within a sliding window. Interesting multi-scale phenomena observed by the Cluster spacecraft include large-scale motion of the current sheet and bursty bulk flow associated turbulence, interpreted as a cross-scale coupling (CSC) process.

    Earthshine: A deep-space small satellite to examine the Sun-Earth connection

    , Pages: 543-553

    The Earth-Sun-Heliosphere Interactions Experiment (EARTHSHINE) mission will be the first deep-space mission designed, developed and executed solely by the UK. Providing a novel concept for a low-cost, fast, responsive project, EARTHSHINE builds on the UK's past involvement in small satellite development. Each of EARTHSHINE's four instruments is carefully designed to answer key questions about how Earth's climate and space environment are influenced by the Sun. EARTHSHINE will have a unique and continuous view of the dayside of the Earth yielding accurate measurements of the Earth's albedo and will simultaneously monitor the electromagnetic, particle and field outputs of the Sun. A coherent design philosophy is presented here based on the requirements that the spacecraft be simple, robust, have minimal operations workload and be based almost entirely on existing commercial off-the-shelf (COTS) equipment. This is achieved by using autonomous systems and on-board processing, thereby reducing operations to an absolute minimum. Many of the spacecraft systems processing duties have been integrated into the EADS Astrium UNIONICS package. The mission will also be the first to use Astrium's new UNIWIND carbon fibre structure which greatly simplifies the construction. The result is a highly independent, low mass (< 130kg) deep-space satellite that is scheduled to be launched in 2007. Copyright © 2003 by the International Astronautical Federation.

    Interplanetary and solar surface properties of coronal holes observed during solar maximum

    , Journal of Geophysical Research: Space Physics, Vol: 108

    Data from the Solar Wind Ion Composition Spectrometer (SWICS) on board the Ulysses spacecraft and synoptic maps from Kitt Peak are used to analyze the relatively short-lived coronal holes which exist during the maximum phase of the solar activity cycle 23. They are compared with the persistent polar coronal holes which prevail around solar minimum. A solar wind velocity increase coinciding with a shift of the ionic charge composition toward lower charge states serves as a robust criterion for identifying solar wind streams emanating from solar maximum holes. This allows an unambiguous association of every stream identified in interplanetary space with a coronal hole on the solar surface with consistent magnetic polarity. Solar wind streams emanating from the solar maximum holes generally show lower velocities of 400 to 600 km/s compared to the polar hole stream velocities of 700 to 800 km/s. However, the SWICS 07+/O6+ charge-state ratios, which are a proxy for coronal temperatures, do not reveal a consistent difference. Though a number of solar maximum holes have a significantly, up to three times, higher temperature compared to the polar coronal holes, the majority of the investigated holes and specifically those with new cycle polarity have a coronal temperature within the range of polar hole temperatures. Likewise, the magnetic flux density in the solar maximum holes and in the polar coronal holes, as derived from the synoptic maps, is not strikingly different. Therefore any intrinsic difference between solar maximum holes and polar coronal holes is small. The striking discrepancy in their kinetic properties, namely the slower velocity of the solar wind streams emanating from solar maximum holes, may partly be attributed to deceleration of the solar wind during propagation to the spacecraft. The discrepancy may also be influenced by active regions in close proximity to the coronal holes, which presumably is more likely for smaller holes. There may, however, be a

    The role of atlantic ocean-atmosphere coupling in affecting North Atlantic oscillation variability

    , Geophysical Monograph Series, Pages: 147-172

    We review the role of ocean-atmosphere interactions over the Atlantic sector in North Atlantic Oscillation (NAO) variability. The emphasis is on physical mechanisms, which are illustrated in simple models and analyzed in observations and numerical models. Some directions of research are proposed to better assess the relevance of Atlantic air-sea interactions to observed and simulated NAO variability.
