INTERNATIONAL UNION OF GEODESY AND GEOPHYSICS UNION GEODESIQUE ET GEOPHYSIQUE INTERNATIONALE

Together we have explored the impacts of the profile of soot within the atmosphere on atmospheric temperature profiles, the formation of ozone in the troposphere, the formation of secondary organic aerosols, and the interactions of aerosols with warm-phase, mixed phase and cirrus clouds. [...] The local organisers of IUGG2023 will consider, irrespective of the further development of the COVID19 pandemic situation, a hybrid assembly taking place both in Berlin and online so that the advantages of the current development of digital conferencing can be shared by many more colleagues in the scientific community. [...] IAGA-IASPEI Joint Scientific Assembly 2021 The Joint Scientific Assembly of the International Association of Geomagnetism and Aeronomy (IAGA) and the International Association of Seismology and Physics of the Earth’s Interior (IASPEI) will be organised from 21 to 27 August 2021 on a fully virtual platform. [...] These include the Permanent Service for Mean Sea Level (PSMSL) of IAG responsible for the collection, publication, analysis and interpretation of sea level data from the global network of tide gauges; the IAPSO Standard Seawater Service - the only internationally recognised standard for the calibration of salinity measurement devices; the IAHS office based at the UK Centre for Ecology & Hydrology. [...] Nominations for the annual Prize are made by National Committees to IAHS, National Committees to the UNESCO-IHP or National Hydrological Advisors to the WMO, and forwarded to the Secretary General of IAHS for consideration by the Nomination Committee.
