    Abstract. We present observations from the magnetopause to the ground during periods of large amplitude, transient dynamic pressure pulses in the magnetosheath. While individual magnetosheath pulses are sharp and impulsive, the magnetospheric response is much smoother with frequencies in the Pc5-6 range being excited in the compressional and poloidal components of the magnetic field. We show that the magnetopause acts like a low pass filter, suppressing timescales shorter than a few minutes. Further filtering appears to occur locally within the magnetosphere, which may be due to the unusual field line resonance frequency profile on this day. Ground magnetometer and radar data along with equivalent ionospheric currents show signatures of travelling convection vortices, similar to the response from pressure variations of solar wind origin. However, the signatures are associated with groups of magnetosheath pulses rather than individual ones due to the impulsive nature of the pressure variations. Thus the scale-dependent magnetospheric response to these transient pressure variations, results in coherent signatures on longer timescales than any individual pulse.

    Operations for two spacecraft of triple-cubesat mission trio-cinema with a single rf chain

    , Pages: 4240-4245, ISSN: 0074-1795

    TRiplet Ionospheric Observatory - Cubesat for Ion, Neutral, Electron and MAgnetic fields (TRIO-CINEMA) mission consists of three identical 3U cubesats for scientific observation. The TRIO-CINEMA mission will provide high sensitivity mapping and high cadence measurements of ring current Energetic Neutral Atom (ENA) in the range of 4 - 200 keV with 1 keV FWHM energy resolution in Low Earth Orbit (LEO). Each spacecraft is equipped with a Supra Thermal Electrons, Ions, Neutrals (STEIN) instrument and a MAGnetometer 911今日黑料 College (MAGIC) instrument. STEIN instrument is improved from those in SupraThermal Electron (STE) instrument flown on NASA's Solar TERrestrial Relations Observatory (STEREO) spacecraft and is capable of identifying electrons, positive ions and neutrals through the application of an electric field in the entrance aperture. MAGIC is dual 3-axis magnetoresistive sensor for attitude control and scientific measurement. First spacecraft of TRIO-CINEMA is developed and will be operated by Space Science Laboratory of University of California, Berkeley (UCB). Another two spacecraft are developed by Kyung Hee University (KHU) in Republic of Korea. TRIO-CINEMA is expected to provide stereo imaging of ENAs and multi-point measurements of ions, electrons and Earth magnetic fields. It is also expected that the TRIO-CINEMA measurements will complement the measurements with NASA's Radiation Belt Storm Probes (RBSP) mission by stereo imaging of the ring current through ENA measurements at low altitudes. TRIO-CINEMA data will be transmitted at 1 Mbps via S-band, whereas a UHF receiver is used for uplink communication. UCB will operate the mission via Mission Operations Center (MOC) and Berkeley Ground Station (BGS) of Space Science Laboratory (SSL). KHU has constructed a new ground station with one UHF RF system for uplink. The two KHU's spacecraft will be initially contiguous with each other deployed from the same launcher. Because the ground S-band antenna can prov

    We quantify the effect of the snow-albedo feedback on Swiss spring temperature trends using daily temperature and snow depth measurements from six station pairs for the period 1961–2011. We show that the daily mean 2-m temperature of a spring day without snow cover is on average 0.4 °C warmer than one with snow cover at the same location. This estimate is comparable with estimates from climate modelling studies. Caused by the decreases in snow pack, the snow-albedo feedback amplifies observed temperature trends in spring. The influence is small and confined to areas around the upward-moving snow line in spring and early summer. For the 1961–2011 period, the related temperature trend increases are in the order of 3–7 % of the total observed trend.

    We present a measurement of the scale-dependent, three-dimensional structureof the magnetic field fluctuations in inertial range solar wind turbulence withrespect to a local, physically motivated coordinate system. The Alfvenicfluctuations are three-dimensionally anisotropic, with the sense of thisanisotropy varying from large to small scales. At the outer scale, the magneticfield correlations are longest in the local fluctuation direction, consistentwith Alfven waves. At the proton gyroscale, they are longest along the localmean field direction and shortest in the direction perpendicular to the localmean field and the local field fluctuation. The compressive fluctuations arehighly elongated along the local mean field direction, although axiallysymmetric perpendicular to it. Their large anisotropy may explain why they arenot heavily damped in the solar wind.

    [1] Substantial biases in shortwave cloud forcing (SWCF) of up to ±30 W m−2are found in the midlatitudes of the Southern Hemisphere in the historical simulations of 34 CMIP5 coupled general circulation models. The SWCF biases are shown to induce surface temperature anomalies localized in the midlatitudes, and are significantly correlated with the mean latitude of the eddy鈥恉riven jet, with a negative SWCF bias corresponding to an equatorward jet latitude bias. Aquaplanet model experiments are performed to demonstrate that the jet latitude biases are primarily induced by the midlatitude SWCF anomalies, such that the jet moves toward (away from) regions of enhanced (reduced) temperature gradients. The results underline the necessity of accurately representing cloud radiative forcings in state鈥恛f鈥恡he鈥恆rt coupled models.
