IASI-NG CNES via EUMETSAT MetOp-SG is a follow-on to the current, first generation series of MetOp satellites, which is now established as a cornerstone of the global MWS ESA – MetOp-SG network of meteorological satellites. RO ESA – MetOp-SG The MetOp-SG programme is being implemented in collaboration with EUMETSAT. 3MI ESA – MetOp-SG ESA will develop the prototype MetOp-SG satellites (including associated instruments) and procure, on behalf of EUMETSAT, the recurrent Sentinel-5 ESA – GMES satellites (and associated instruments). The overall MetOp-SG space segment architecture consists of two series of satellites (Sat-A, Sat-B), each carrying different suites of instruments and operating in LEO polar orbit. The planned launches of the first of each series of satellites Sat-B SCA ESA – MetOp-SG are at the beginning of 2021 and at end 2022, respectively.

The EUMETSAT Polar System 13+ Successful Years of Global Observations for Operational Weather Prediction and Climate Monitoring K
Article The EUMETSAT Polar System 13+ Successful Years of Global Observations for Operational Weather Prediction and Climate Monitoring K. Dieter Klaes, Jörg Ackermann, Craig Anderson, Yago Andres, Thomas August, Régis Borde, Bojan Bojkov, Leonid Butenko, Alessandra Cacciari, Dorothée Coppens, Marc Crapeau, Stephanie Guedj, Olivier Hautecoeur, Tim Hultberg, Rüdiger Lang, Stefanie Linow, Christian Marquardt, Rosemarie Munro, Carlo Pettirossi, Gabriele Poli, Francesca Ticconi, Olivier Vandermarcq, Mayte Vasquez, and Margarita Vazquez-Navarro ABSTRACT: After successful launch in November 2018 and successful commissioning of Metop-C, all three satellites of the EUMETSAT Polar System (EPS) are in orbit together and operational. EPS is part of the Initial Joint Polar System (IJPS) with the United States (NOAA) and provides the service in the midmorning orbit. The Metop satellites carry a mission payload of sounding and imaging instruments, which allow provision of support to operational meteorology and climate monitoring, which are the main mission objectives for EPS. Applications include numerical weather prediction, atmospheric composition monitoring, and marine meteorology. Climate monitoring is supported through the generation of long time series through the program duration of 20+ years. The payload was developed and contributed by partners, including NOAA, CNES, and ESA. EUMETSAT and ESA developed the space segment in cooperation. The system has proven its value since the first satellite Metop-A, with enhanced products at high reliability -

On August 25, 2018 the interplanetary counterpart of the August 20, 2018 Coronal Mass Ejection (CME) hit the Earth, giving rise to a strong G3 geomagnetic storm. We present a description of the whole sequence of events from the Sun to the ground as well as a detailed analysis of the observed effects on the Earth’s environment by using a multi instrumental approach. We studied the ICME propagation in the interplanetary space up to the analysis of its effects in the magnetosphere, 5 ionosphere and at ground. To accomplish this task, we used ground and space collected data, including data from CSES (China Seismo Electric Satellite), launched on February 11, 2018. We found a direct connection between the ICME impact point onto the magnetopause and the pattern of the Earth’s polar electrojects. -

OGLE2-TR-L9: an Extrasolar Planet Transiting a Fast-Rotating F3 Star

Photometric observations for the OGLE-II microlens monitoring campaign have been taken in the period 1997−2000. All light curves of this campaign have recently been made public. Our analysis of these data has revealed 13 low-amplitude transiting objects among ∼15700 stars in three Carina fields towards the galactic disk. One of these objects, OGLE2-TR-L9 (P∼2.5 days), turned out to be an excellent transiting planet candidate. Aims. In this paper we report on our investigation of the true nature of OGLE2-TR-L9, by re-observing the photometric transit with the aim to determine the transit parameters at high precision, and by spectroscopic observations, to estimate the properties of the host star, and to determine the mass of the transiting object through radial velocity measurements. -
Joint IAGA IASPEI Symposia J1 Earth and Planetary Core Structure and Evolution from Observations and Modelling Conveners
Joint IAGA IASPEI Symposia J1 Earth and planetary core structure and evolution from observations and modelling Conveners: Christopher Davies ([email protected]) Swarandeep Sahoo ([email protected]) Kimberly Moore ([email protected]) Christine Thomas ([email protected]) Recent advances in the theory and observation of planetary cores is providing profound insight into these remote and enigmatic regions. The Juno and Cassini missions have revealed the properties of Jupiter's magnetic and gravity fields in unprecedented detail, while results from forthcoming missions such as BepiColombo and InSight promise a step change in our knowledge of the interior structure and dynamics of terrestrial bodies within our solar system. Complementary theoretical developments have advanced our understanding of nucleation and crystallization of solids within planetary cores and how these processes influence the generation of global magnetic fields over geological timescales. Numerical simulations of the dynamo process are pushing towards the extreme conditions of rapidly rotating magnetic turbulence that are thought to characterize many planetary cores, promising new insights into the field generation process and the origin of observed magnetic secular variation. On Earth, novel seismic data processing techniques are being combined with vast datasets to illuminate core-mantle interactions and anomalous structures in the liquid and solid cores, while mineral physics calculations and experiments are now capable of estimating transport properties at the extreme pressure-temperature conditions of the core-mantle boundary. Observations of Earth's magnetic field magnitude and its secular variation have been used to infer various physical processes such as core flow patterns, inner core growth, thermal and compositional evolution of the core, and their fundamental origin.
