    • Mapping the dependence of black carbon radiative forcing on emission region and season 

      Räisänen, Petri; Merikanto, Joonas; Makkonen, Risto; Savolahti, Mikko; Kirkevåg, Alf; Sand, Maria; Seland, Øyvind; Partanen, Antti-Ilari (Peer reviewed; Journal article, 2022)
      For short-lived climate forcers such as black carbon (BC), the atmospheric concentrations, radiative forcing (RF), and, ultimately, the subsequent effects on climate, depend on the location and timing of the emissions. ...

    • Technical note: Emulation of a large-eddy simulator for stratocumulus clouds in a general circulation model 

      Nordling, Kalle; Keskinen, Jukka-Pekka; Romakkaniemi, Sami; Kokkola, Harri; Räisänen, Petri; Lipponen, Antti; Partanen, Antti-Ilari; Ahola, Jaakko; Tonttila, Juha; Alper, Muzaffer Ege; Korhonen, Hannele; Raatikainen, Tomi (Peer reviewed; Journal article, 2024)
      Here we present for the first time a proof of concept for an emulation-based method that uses a large-eddy simulations (LESs) to present sub-grid cloud processes in a general circulation model (GCM). We focus on two key ...
