TL;DR: The Metrology for Meteorology (MeteoMet) project as mentioned in this paper is an attempt to bridge the meteorological and metrological communities, which is the concept of traceability, an idea used in both fields but with a subtle difference in meaning.
Journal ArticleDOI
Magnetosheath control of solar wind-magnetosphere coupling efficiency
Tuija Pulkkinen,Andrew Dimmock,Antti Lakka,Adnane Osmane,Emilia Kilpua,Minna Myllys,Eija Tanskanen,Eija Tanskanen,Ari Viljanen +8 more
TL;DR: In this article, the role of the magnetosheath in solar wind-magnetosphere-ionosphere coupling was examined using the Time History of Events and Macroscale Interactions during Substorms plasma and magnetic field observations in the magnetoheath together with OMNI solar wind data and auroral electrojet recordings from the International Monitor for Auroral Geomagnetic Effects (IMAGE) magnetometer chain.
Journal ArticleDOI
Development of a primary standard for dynamic pressure based on drop weight method covering a range of 10 MPa–400 MPa
TL;DR: In this paper, the authors present a primary standard for dynamic pressures that is based on the drop weight method, where a pressure pulse is generated by impact between a dropping weight and a piston of a liquid-filled piston-cylinder assembly.
Journal ArticleDOI
The Cross-Polar Cap Saturation in GUMICS-4 During High Solar Wind Driving
Antti Lakka,Tuija Pulkkinen,Andrew Dimmock,Minna Myllys,Minna Myllys,Ilja Honkonen,Minna Palmroth +6 more
TL;DR: In this paper, the authors used the Grand Unified Magnetosphere-Ionosphere Coupling Simulation (GUMICS‐4) and artificial solar wind data to mimic weak and strong driving in order to study the Earth's ionospheric cross-polar cap potential (CPCP) response to a wide range of IMF magnitudes (3.5 nT − 30 nT) and upstream Alfven Mach number values (1.2 − 22).
Journal ArticleDOI
The impact on global magnetohydrodynamic simulations from varying initialisation methods: results from GUMICS-4
Antti Lakka,Tuija Pulkkinen,Andrew Dimmock,Adnane Osmane,Ilja Honkonen,Minna Palmroth,Pekka Janhunen +6 more
TL;DR: In this article, the effects of different initialisation methods of the GUMICS-4 global magnetohydrodynamic (MHD) simulation to the dynamics in different parts of the Earth's magnetosphere were investigated.
