The Arctic is especially vulnerable to climate change since it is warming more than twice the global average. Aerosols and clouds play a major role regulating the energy transport from and to space. Within NASCENT 2019-2020 campaign (Ny-Ålesund AeroSol Cloud ExperimeNT) , we will study in depth microphysical and chemical properties of aerosols and clouds using a variety of novel instruments. This field campaign is funded by the Knut and Alice Wallenberg Foundation, the Swedish Research council (VR) and the Horizon 2020 project FORCeS. Our observations are linked to the MOSAiC year (2019-2020).

We are using Twitter to update on our campaign progress (see here or list below).

Ny-Ålesund is a research community close to 79º North on Svalbard. Intensified observations of cloud and aerosol properties are conducted at Zeppelin observatory at 475 m above sea level. Various in-situ and remote sensing instruments below the mountain will additionally added analysis.
