International Scientific Conference on climate, Paris
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.more on climate conference

Meteor exploding over Ural mountains
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
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
The first ARISE Workshop was held at the University of Reading near London, UK.
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.
ARISE meetings at the EGU2012
During the last European Geosciences Union Conference in Vienna, Austria the ARISE project has been presented at the session "Infrasound for Atmospheric Studies". In addition, two ARISE sessions were organized about project work and about collaborations with associated members.
Arise Kick off meeting
The ARISE kickoff meeting was held in the Abbaye de Vaux de Cernay (France). 45 persons participated to the meeting.
