Solar Orbiter: A mission update

ESA's Solar Orbiter mission will determine in situ the properties of fields and particles in the unexplored near-Sun heliosphere in three dimensions, investigate remotely the fine-scale structures and events in the magnetically coupled layers of the Sun's atmosphere, identify through near-corotation the links between activity on the solar surface and the resulting evolution of the inner heliosp...

Volcanic eruptions observed with infrasound

[1] Infrasonic airwaves produced by active volcanoes provide valuable insight into the eruption dynamics. Because the infrasonic pressure field may be directly associated with the flux rate of gas released at a volcanic vent, infrasound also enhances the efficacy of volcanic hazard monitoring and continuous studies of conduit processes. Here we present new results from Erebus, Fuego, and Villar...

Experimental Approach of Reflectance Based Vicarious Calibration Method for Solar Reflectance Wavelength Region of Sensor Onboard Remote Sensing Satellites

Experimental approach of reflectance based vicarious calibration of solar reflectance wavelength region of mission instruments onboard remote sensing satellites is conducted. As an example, vicarious calibration of ASTER/VNIR with estimated aerosol refractive index and size distribution that depends on atmospheric conditions is discussed. Strange solution of estimated refractive index and size ...

Martian clouds observed by Mars Global Surveyor Mars Orbiter Camera

[1] We have made daily global maps that cover both polar and equatorial regions of Mars for Ls 135 –360 and 0 –111 using the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) red and blue wide-angle swaths taken from May 1999 to January 2001. We study the seasonal distribution of condensate clouds and dust clouds during roughly 1 Martian year using these daily global maps. We present the dev...
