Longwave and shortwave cloud radiative forcing (CRF) derived from broadband irradiance observations (doi:10.1594/PANGAEA.936232) during the MOSAiC-ACA (Multidisciplinary drifting Observatory for the Study of Arctic Climate - Airborne observations in the Central Arctic) campaign in September 2020. This dataset contains only low-level flight sections. In addition, a cloud liquid water path (LWP) equivalent derived from the shortwave transmissivity is given and a cloud-free albedo estimate during cloudy observations. CRF, LWP equivalent, and the cloud-free albedo were derived using the method described by Stapf et al. (2020).
