CHAMOS workshop in Sodankylä, Finland
The CHAMOS 2023 Workshop was organised by SGO on 27th Nov - 1st at Luosto, Sodankylä. After a series of on-line meetings, we had five days of face-to-face collaboration, discussions, and presentations. Among the topics were updates to electron forcing data set for CMIP7, and progress in SUNVAC and HISSA projects. Thank you for a nice meeting!
Academy project GERACLIS accepted!
Academy of Finland funds GERACLIS, a joint project between SGO/University of Oulu and FMI. We aim to understand how the Earth's atmosphere and climate respond to drastic changes in geomagnetic field configuration expected over a thousand year time span. The project runs between 2023 and 2027 and utilises the WACCM and SOCOL models and Finnish HPC resources provided by CSC. See the GERACLIS webpage here
Pekka visits ISEE, Japan!
In February-May, Pekka is working as a visiting professor at the Institute for Space-Earth Environmental Research (ISEE), Nagoya University. Scientifically, we will address the mesospheric ozone variability and its drivers such as EPP forcing on daily to seasonal timescales using ground-based and satellite-base observations together with atmospheric simulations.The visit is hosted by Yoshizumi Miyoshi.
Nature Communications publication!
Monika et al. have published a paper on stratospheric temperature response to EPP-driven ozone depletion. A statistical analysis of WACCM simulations shows that a 25% reduction in polar upper stratospheric ozone indeed leads to 3 Kelvin decrease in temperatures. Our study also highlights the urgent need for an improved representation of decadal solar particle forcing in climate simulations. Read the Nature Communication paper here
VERSIM Workshop at SGO
SGO organised the VLF-ELF Remote Sensing of the Ionospheres and Magnetospheres Workshop from 7th to 11th of November, 2022. With the topics including sources and measurements of EPP, many CHAMOS scientists were attending. Workshop web pages are here
ISSI team meeting in Bern
International Space Science Institute in Bern hosted and funded our second meeting of the Space Weather Induced Ionisation Effects on the Ozone Layer project on 5-9 September, 2022. After a two-year delay due to the virus, it is nice to get together again! Project web page is here
CHAMOS work at FMI
A spring meeting between SGO and FMI teams was organised in Helsinki. In addition to face-2-face, hands-on work together, we also had project meetings for both SUNVAC and HISSA!
Academy of Finland funds the HISSA project!
HISSA consortium between University of Helsinki, SGO/University of Oulu and CSC unite forces to study ionosphere by using the latest Finnish supercomputers for the next 3 years! Here SGO's task is to develop new analysis methods for the upcoming EISCAT_3D, including a routine-basis inversion of EPP characteristics as a new data product. Our humble aim is also to design the best D-region radar experiment in the world!
Pekka joins CAIRT MAG
The European Space Agency has selected Pekka Verronen for the CAIRT Mission Advisory Group. CAIRT (The Changing-Atmosphere Infra-Red Tomography Explorer) is one of the four Earth Explorer 11 mission candidates entering Phase 0. The role of MAG is to provide the most robust basis for a rigorous and feasible mission definition, in particular through the consolidation of requirements, by identifying and addressing concerns and challenges, and proactively challenging the proposal and proposed concepts, all needed to successfully pass through the next evaluation step. More on the Earth Explorer 11 missions.
Pekka joins the EISCAT council
The Academy of Finland has named Pekka Verronen into its EISCAT Council delegation as a scientific representative for the year 2021. The EISCAT Council is the governing body of EISCAT Scientific Association and has an overall responsibility for the activities of the Association. More on the EISCAT council.
