International Scientific Conference on climate, Paris

7-10 July 2015

ARISE contributes to organize the session "Stratosphere and Middle Atmosphere" in the theme "State of Knowledge on Climate Change". The session addresses recent research on the middle atmosphere dynamics and changing composition, and their connections to the troposphere and the surface. Contributions are expected on observed changes in stratospheric circulation and composition, on numerical simulations of the middle atmosphere and its coupling to the troposphere in response to the greenhouse gas increase, and other processes related to climate change.

    Meteor exploding over Ural mountains

    15 February 2013 at 03:20 UTC

    A large meteorite disintegrated over the Ural Mountains 1500 km east of Moscow. The shock wave of the explosion injured about 1,500 people and caused extensive damages over a large region located around the city of Chelyabinsk (photograph from video camera, NEproskochil/YouTube). This event, with the explosion of the Sulawesi meteorite on October 8, 2009, is one of the most powerful ever recorded by the CTBTO infrasound network. Acoustic waves generated by the explosion were detected by 20 infrasound stations and traveled around the globe.

    Stratospheric warming Event

    January 2013

    Sudden stratospheric warmings (SSWs) are characterized by a rapid increase in temperature in the polar winter stratosphere and a weakening of the polar vortex of westerly winds. Stratospheric temperature can increase up to several tens of Kelvins and the polar vortex can reserve direction, also inverting the infrasound ducting channel. The Figure shows the temperature evolution observed with Lidar above South of France (OHP, 44șN) during the Sudden Stratospheric Warming of January 2013. Warming starts in the upper stratosphere (50 km) and slowly increases in amplitude with a shift in altitude (to 40 km) up to a maximum of 30 K above the climatology model (in red). Maps are provided by MIMOSA simulations.

    First ARISE workshop at University of Reading, UK

    18-21 September 2012

    The first ARISE Workshop was held at the University of Reading near London, UK.

    Observation campaigns

    13 July 2012

    The first campaign using simultaneously the three technologies starts at the Observatoire de Haute Provence. The duration of the campaign will be one year to observe seasonal effects. Objectives are to identify advanced parameters and to improve processing methods to better characterize gravity waves.
    The second campaign is organized near Etna volcano, which has been very active this year. Near-field infrasound stations completed by mobile infrasound arrays and airglow observations are used to analyze the volcanic source and the propagation effects for the determination of advanced parameters related to extreme events.
