The Institute of Atmospheric Sciences and Climate (CNR-ISAC) aims at an integrated scientific understanding of the atmosphere, the ocean and their processes, by means of a multidisciplinary approach which combines scientific and technological skills in meteorology, climate, atmospheric dynamics and composition, Earth observations; it develops basic research, theoretical, experimental and numerical, and modeling work together with impact evaluation.
ISAC is the largest CNR Institute on atmospheric sciences, structured in 7 Units over the country, 7 permanent observatories, including 2 Global Stations of the Global Atmosphere Watch (GAW) program of the World Meteorological Organization (WMO) and 2 atmospheric research Supersites.
ISAC is recognised internationally through its collaboration with a large number of European laboratories, and research centers worldwide.

March 23, 2017. The World Meteorological Organization (WMO) has released its updated version of the International Cloud Atlas ( in conjunction with the World Meteorological Day.  
The Atlas is the global reference for observing and classifying clouds and other weather phenomena. For the first time, the 2017 edition will primarily be a web-based portal, allowing for much richer content and presentation easily accessible to a vast audience.


The ESR network (European Skynet Radiometer network, represented by Monica Campanelli (ISAC-CNR), is attending the measurement campaign PRE-TECT ( , with a PREDE POM01 sun-sky radiometer.
