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 3 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.

The observations of the ISAC-CNR station of Monte Cimone, part of the GAW (Global Atmosphere Watch) network, have been used for the preparation of a press release by the WMO (World Meteorological Organization): it is too early to draw definitive conclusions on the importance of decreases recorded in March 2020 as regards concentrations of greenhouse gases, but be careful of the post-crisis and not to forget Climate Actions.

Ministro Costa alle Svalbard con delegazione CNR

Il Ministro dell'Ambiente Costa ha trascorso due giorni alle Svalbard, presso la base italiana del Cnr di Ny Alesund, mettendo al centro della visita i cambiamenti climatici. Il Ministro è stato accompagnato dalla delegazione del Cnr composta dal direttore del Dipartimento Scienze del Sistema Terra e Tecnologie per l'Ambiente Fabio Trincardi, dalla ricercatrice ISAC Elisa Palazzi, dal direttore facente funzione dell’ISP Leonardo Langone e dal neodirettore Carlo Barbante.

PM10, atmospheric pollution

Smoke in the valleys: the 'case' of the Sacco valley in Italy investigated by ISAC "Aerolab"


In the Italian environmental rankings, the “small” town of Frosinone is among the most polluted in Italy in terms of atmospheric particulate (PM10)

To understand the reasons of such a situation, the CNR-ISAC researchers installed an instrument to measure the “black carbon” fraction of PM10, discovering that the main component of the pollution comes from the wood combustion. Such component is crucial in exceeding the legal threshold

Stabilizzare le concentrazioni di CO2 in atmosfera avrebbe, nell’immediato, un effetto benefico sulle piogge di alcune regioni a clima mediterraneo. Lo studio condotto dal Cnr-Isac in collaborazione con l’Università di Reading, è pubblicato sulla rivista Pnas
