The role of the World Data Centers in handling ocean climate data
The World Data Center System, set up for the International Geophysical Year in 1957, is an international network of data centers that links data contributors to data users in the geosciences. It includes means for the synthesis, analysis, and preparation of data products. It was set up in response to the needs of the international scientific community, and is still overseen by non-governmental scientific organizations. Because it is freely available to researchers in all countries, the World Data Center System has a special role to play in support of ocean climate research and monitoring programs. The World Data Centers face a number of challenges today. Apathy is probably the greatest, since many scientists take the system for granted. There is need to improve access and exploit new technology. The system must establish new links to assure continuity in a world with political changes. The multidisciplinary needs of global change research will demand capabilities for data and information management that go beyond the traditional emphasis on geophysics
Report of the panel on international programs
The panel recommends that NASA participate and take an active role in the continuous monitoring of existing regional networks, the realization of high resolution geopotential and topographic missions, the establishment of interconnection of the reference frames as defined by different space techniques, the development and implementation of automation for all ground-to-space observing systems, calibration and validation experiments for measuring techniques and data, the establishment of international space-based networks for real-time transmission of high density space data in standardized formats, tracking and support for non-NASA missions, and the extension of state-of-the art observing and analysis techniques to developing nations

The intensification of metallic layered phenomena above thunderstorms through the modulation of atmospheric tides
We present a multi-instrument experiment to study the effects of tropospheric thunderstorms on the mesopause region and the lower ionosphere. Sodium (Na) lidar and ionospheric observations by two digital ionospheric sounders are used to study the variation in the neutral metal atoms and metallic ions above thunderstorms. An enhanced ionospheric sporadic E layer with a downward tidal phase is observed followed by a subsequent intensification of neutral Na number density with an increase of 600 cmâ3 in the mesosphere. In addition, the Na neutral chemistry and ion-molecule chemistry are considered in a Na chemistry model to simulate the dynamical and chemical coupling processes in the mesosphere and ionosphere above thunderstorms. The enhanced Na layer in the simulation obtained by using the ionospheric observation as input is in agreement with the Na lidar observation. We find that the intensification of metallic layered phenomena above thunderstorms is associated with the atmospheric tides, as a result of the troposphere-mesosphere-ionosphere coupling
Tuzo Wilson in China: Tectonics, Diplomacy and Discipline During the Cold War
Canadian geophysicist John Tuzo Wilson\u27s transform fault concept was instrumental in unifying the various strands of evidence that together make up plate tectonic theory. Outside of his scientific research, Wilson was a tireless science administrator and promoter of international scientific cooperation. To that end, he travelled to China twice, once in 1958 as part of the International Geophysical Year and once again in 1971. Coming from a rare non-communist westerner in China both before and after the Cultural Revolution, Wilson\u27s travels constitute valuable temporal and spatial cross-sections of China as that nation struggled to define itself in relation to its past, to the Soviet Union which inspired its politics, and to the West through Wilson\u27s new science of plate tectonics. In so constructing these cross-sections, Wilson acts as a kind of cartographer of science, mapping the tectonic shifts during the Cold War, which revolutionized his understanding of the earth, of politics, and of the discipline of geophysics

The Global Open Science Cloud: Vision and Initial Successes
The Global Open Science Cloud has the potential to advance the way scientific data and resources are shared and accessed, and how global collaboration happens. However, addressing the challenges associated with its creation and ensuring inclusivity, interoperability, data privacy, and sustainability are crucial for its success. The collaborative efforts of stakeholders from different disciplines, regions, and sectors will be essential in realising the vision of a truly global and open science platform. The achievements of GOSC so far, including successful collaborations, funded projects, and the development of a common reference framework, demonstrate its potential and progress towards its goals
