Erkka visited FMI

Erkka spent three weeks of August at FMI in Helsinki, working with Pekka on WACCM-D ionospheric simulations and comparison against ground-based observations of cosmic radio noise absorption during solar proton events.

Contribution to the CMIP6 solar forcing

Pekka, Craig, Mark, Monika, Annika, and Max are among the authors of the CMIP6 solar forcing paper, now published in the special issue Coupled Model Intercomparison Project Phase 6 (CMIP6) Experimental Design and Organization. Our contribution is the medium-energy electron precipitation from the outer radiation belt. Access the paper here.

EISCAT_3D construction given green light!

EISCAT_3D, the next generation radar system gets go-ahead for construction. The scientific aim is to understand the effect of solar storms and space weather on the upper atmosphere in the Arctic. More about the good news here!

Pulsating aurora meeting at ISEE

Esa and Antti visited ISEE to discuss the status of our plans for pulsating aurora studies and publications with Shin and Shinji. Check out our latest joint JGR publication here.

CHAMOS workshop in Helsinki, Finland

The annual CHAMOS team workshop will be held in Helsinki, Finland from 30 October to 3 November, 2017. The plan is to have five days of intensive collaboration, this time in an urban environment. See you there!

EEP meeting at BAS

Niilo, Max, Pekka, and Craig visited Mark and Annika at the British Antarctic Survey. Three days of collaboration on energetic electron precipitation and its atmospheric and climate effects was combined with an afternoon walk around the historic colleges of the University of Cambridge. See a group photo here.

Esa and Pekka visited Nagoya University

Esa and Pekka visited Yoshi, Shin, Shinji, and Antti at ISEE. We all participated in the annual Pulsating Aurora Workshop and discussed our joint research, especially related to the first coordinated campaign of ERG satellite (now named ARASE) observations and ground-based ionospheric measurements.

ERG satellite launch successful

JAXA has successfully launched the ERG satellite to orbit! Important to CHAMOS, measurements of energetic electrons can now be made using the Plasma Particle Experiment Suite (PPE) which has 62 energy channels in the range of 10 eV to 20 MeV. Congratulations to the ISEE ERG team! More information about the ERG mission.

CHAMOS workshop in Luosto, Lapland

Amazing Luosto provided perfect conditions for the 2016 CHAMOS workshop. Our week of intensive hands-on collaboration, discussions, and presentations was again very successful. Our group photograph can be seen here.

Center of Excellence first-round success

SGO and FMI are members of the 3DGeoSpace consortium, with Esa leading. Our proposal was selected for the second round in the Center of Excellence call by the Academy of Finland! A lot of work is now needed to write a full application. We can do it!

CHAMOS workshop in Luosto, Lapland

The annual CHAMOS team workshop will be held again in Luosto, Sodankylä, Finland from 28 November to 2 December, 2016. The plan is to have five days of intensive collaboration in a remote log cabin, see you there!

A paper on long-term modeling of electron precipitation

Max, Annika, Mark, Craig, and Pekka published a model for 30-1000 keV radiation belt driven electron precipitation, designed for calculations of decadal time series of atmospheric ionization. The paper is part of the special section Energetic Electron Loss and its Impacts on the Atmosphere. Access the paper.

A paper on pulsating aurora published

Esa, Antti, Pekka, Yoshizumi, Shin-Ichiro, and Shinjin published a paper on mesospheric ozone depletion associated with pulsating aurora. It is part of the special section Energetic Electron Loss and its Impacts on the Atmosphere. Access the paper here.

Antti at Nagoya University

Antti has started a 6-month Designated Associate Professorship in Institute for Space-Earth Environmental Research (ISEE) at Nagoya University! The scope of the visit relates closely to the CHAMOS science.

A book chapter on radiation belts electrons, polar atmosphere and climate

Mark, Craig, Monika, Annika and Pekka have written a chapter called Linkages Between the Radiation Belts, Polar Atmosphere and Climate: Electron Precipitation Through Wave Particle Interactions, which part of the book Waves, Particles, and Storms in Geospace. Access the book.

HEPPA-SOLARIS Workshop at FMI

Pekka, Craig, Esa, Monika, Niilo, Antti, Erkki, Johanna, Mark, and Shin participated in the 6th International HEPPA-SOLARIS Workshop in Helsinki, Finland, on 13-17 June, 2016. Topic: Influences of solar radiation and energetic particle precipitation on the atmosphere and climate. More information here.

Space Climate Symposium

Esa and Pekka participated in the 6th Space Climate Symposium in Kittilä, Finland. There was also some time for joint work on funding applications. Fun! More about the Space Climate Meeting here.

CHAMOS workshop in Luosto, Lapland

Snowy Luosto provided the excellent conditions for the 2015 CHAMOS workshop. 5-days of intensive collaboration in a remote log cabin adds to our yearly tradition.

SPARC SOLARIS-HEPPA

Craig, Mark, and Pekka participated in the SPARC SOLARIS-HEPPA working group meeting in Boulder, Colorado. Suggestions of solar input for the CMIP6 climate simulations (which will be the used for the next IPCC report) were outlined, including energetic particle precipitation for the first time! More about the meeting here.

HEPPA-SOLARIS Workshop at FMI

Pekka, Craig, Esa, Monika, and Niilo are in the committees that organize the 6th International HEPPA-SOLARIS Workshop in Helsinki, Finland, on 13-17 June, 2016. The topic is very much CHAMOS-related: Influences of solar radiation and energetic particle precipitation on the atmosphere and climate. More information here.
