Abstract:
Recently, numerous international organizations, like the UN Committee on the Peaceful Uses of Space, the World Meteorological Organization, and the International Civil Aviation Organization, and many countries have announced space weather strategy and action plans to highlight the possible impact on human activities. Especially at the low-latitude region, the electron density distribution is varied rapidly and non-uniform. For instance, higher plasma density during the day time period overhead are recorded associated with the equatorial ionization anomaly, and to easier observe plasma bubbles/irregularities in the evening to midnight period. Such phenomena related to ionospheric space weather significantly influence high-frequency and satellite communication as well as navigation and positioning services. In Taiwan, the Central Weather Administration (CWA) has collaborated with Taiwan Space Agency (TASA) and domestic scientific research teams to establish the Space Weather Operational Office (SWOO) since 2015 to play the role of providing space weather information and forecasts locally. By using ground-based and space-based observations, SWOO provides real-time products to monitor global and regional space weather conditions. These include solar images, GNSS-TEC, ionospheric profile, ion composition, scintillation index, radio frequency interference index, as well as geomagnetic magnitude and disturbance, etc. Meanwhile, a Global Ionospheric Specification (GIS) and an ionosphere - thermosphere coupled assimilation system is operated by combining observations to reproduce three-dimensional electron density structure and short period forecast of ionosphere and thermosphere, respectively. All these monitoring and forecasting products are stable and reliable according to various validations, and now routinely published on the SWOO website. Historical images, analyzed data, raw observations are archived by SWOO, Taiwan Analysis Center for COSMIC (TACC), Taiwan Geophysical Database Management System (GDMS) and Atmospheric Science Research and Application Databank (ASRAD). Most of the data is open freely or part of them are with usage restrictions. Therefore, welcome and encourage the operational center, research community and industry to use those dataset for space weather research and operation.
