Information: - The International Union of Geodesy and Geophysics (IUGG UGGI) is an international non-governmental organisation dedicated to the scientific study of the Earth and its space environment using geophysical and geodetic techniques. - Hydrology is the scientific study of the movement, distribution, and quality of water on Earth and other planets, including the water cycle, water resources and environmental watershed sustainability. A practitioner of hydrology is a hydrologist, working within the fields of earth or environmental science, physical geography, geology or civil and environmental engineering. - Earth, otherwise known as the world, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets. - The International Association of Cryospheric Sciences , or IACS , is the eighth association of the International Union of Geodesy and Geophysics ( IUGG ) . It was launched by the IUGG Council on 2007 - 07 - 04 , developing from the International Commission of Snow and Ice of the International Association of Hydrological Sciences ( IAHS ) via the transitional Union Commission for the Cryospheric Sciences ( UCCS ) . Formation of this new Association is recognition of the importance of the cryosphere in the study of Earth System Science , and particularly at a time of significant global change . Accordingly , cryospheric sciences is an umbrella term for the study of the cryosphere ( not unlike atmospheric sciences , encompassing meteorology , climatology , and aeronomy ) ; as an interdisciplinary Earth science , many disciplines contribute to it , most notably geology , hydrology , and meteorology and climatology ; in this sense , it is comparable to glaciology . IACS has historic connections going back to the establishment of the Commission Internationale des Glaciers ( International Glacier Commission ) in 1894 . The broad objectives of IACS are : to promote studies of the cryosphere ; to encourage research on cryospheric sciences through collaboration ; to foster discussion and publication of results of cryospheric research ; to promote education about the cryosphere ; to facilitate standardisation of cryospheric measurements ; and to promote the science of Permanent Services under IACS responsibility ( at present IACS has responsibility within the International Council of Science for the World Glacier Monitoring Service ( WGMS ) ) . IACS is structured around a number of disciplinary Divisions . Currently these are : Snow and Avalanches ; Glaciers and Ice Sheets ; Marine and Freshwater Ice ; Cryosphere , Atmosphere and Climate ; Planetary and other Ices of the Solar System . A number of working groups under these Divisions address scientific problems of the cryosphere that are timely and well constrained .... - The International Association of Hydrological Sciences (IAHS) is a non-profit non-governmental scientific organization committed to serving the science of hydrology and the worldwide community of hydrologists. The IAHS was established in 1922, and presently claims a membership in excess of 5000, from over 130 countries. Given the paragraphs above, decide what entity has the relation 'instance of' with 'organization'.
Answer:
international association of cryospheric sciences
