Ocean Sciences Perspectives on Integrated, Coordinated, Open, Networked (ICON) Science

Each commentary explores a different perspective, from field sampling and experimentation to remoteu2010sensing and autonomous observations; global collaboration, technology transfer and deployment, reproducibility, and data sharing and infrastructure; increasing diversity and broadening participation in ocean sciences; and field sampling and experimentation. Overall, there is a consensus that ocean sciences has been well-advanced in adopting many of the ICON's u2010FAIR recommendations regarding and u2010fu2010freight's principles, as well as increasing training activities to implement good practices. On the other hand, ocean sciences research is still in its infancy, supporting diversity and broadening participation. We acknowledge that adopting ICONu2010FAIR principles comes at a price tag and efforts, but it has a strong potential to research ocean sciences in several ways.

Day‐to‐Day Variability of the Semidiurnal Tide in the F‐Region Ionosphere During the January 2021 SSW From COSMIC‐2 and ICON

Assimilation is greatly enhanced during the January 2021 Sudden Stratospheric Warming, which was reported in the Ft. tidal spectrum of the global ionosphere obtained from hourly COSMIC u20102 Global Ionospheric Specification data assimilation is much higher during the Fu2010region tidal spectrum. The first data set to determine the tidal weather of the ionosphere on a day-to-u2010 day basis are the first data set to determine the tidal weather of the ionosphere, providing a new perspective on space weather variability triggered by lower and middle atmosphere dynamics.

Penetrating Electric Field Simulated by the MAGE and Comparison With ICON Observation

During September 2020, we simulated the penetrating electric field in the equatorial zone under different interplanetary magnetic field BZ conditions using the newly developed, Multiscale Atmosphere-u2010Geospace Environment model. The MAGE simulations reveal that in southward IMF cases, the dawnu2010dusk electric potential drop at the equator is about 12% of the cross polar cap potential difference. The dawn-u2010dusk potential decrease at the equator changes within a few minutes, according to MAGE's simulation, which in turn alters the vertical ion drift. The daytime changes of the equatorial vertical ion drift in reaction to the IMF's penetrating electric field only half of that during the nighttime. The MAGE simulation shows a pre-u2010reversal increase in southward IMF cases, but the PRE was missing in the ICON IVM observations.

Seasonal Variations of Medium‐Scale Waves Observed by ICON‐MIGHTI

Both medium- and low-scale fluctuations in temperature and winds below 260 km/hr on a 2012-2008 annual average, as well as annual variations of MSP for winds become prominent between 160 and 250 kilometers. Throughout the year, the most significant wind MSP was recorded at u223c110. u2013120 km. Both seasonal variations of MSP between 90 and 250 km altitudes are influenced by differences in both the sources of MSP and changes in the background wind, according to our report.

Neutral Composition Information in ICON EUV Dayglow Observations

A far-u2010UV spectrometer measures the column ratio in the upper thermosphere using dayglow between 54 and 88 nm, while a NASA Ionospheric Connection Explorer spacecraft, which seeks to investigate the relationships between O+ and thermosphere, uses UV airglow in the common way.

ICON‐O: The Ocean Component of the ICON Earth System Model ‐ Global Simulation Characteristics and Local Telescoping Capability

We introduce the ocean general circulation model ICONu2010O of the Max Planck Institute for Meteorology, which is part of the Earth system model ICONu2010ESM's oceanic model. Our results show first, that ICONu2010O on the nearly uniform grid simulates an ocean circulation that compares well with observations, and second, that ICONu2010O in its telescope configuration is capable of reproducing the dynamics in the focal region over decadal time scales at a fraction of the computational cost of the uniform U2010grid simulation.

ICON Observations of Equatorial Ionospheric Vertical ExB and Field‐Aligned Plasma Drifts During the 2020–2021 SSW

During the abrupt stratospheric warming, large anomalies in vertical ExB drift have been found by earlier studies, but no research has been done on field-u2010-aligned plasma drift, as shown by fieldu2010-aligned plasma drift. Using the Ionospheric Connections Explorer satellite measurements, we present the first simultaneous observations of the equatorial ionospheric vertical ExB and field-u2010-aligned plasma drifts and neutral winds during the 2020-2021 SSW. In good accord with the Jicamarca's incoherent scatter radar results, downward ExB drift is seen in the afternoon equatorial topside ionosphere in longitudes of u223c180°u00b0u00b0e-u00b0e.
