Abstract. The EarthCARE Commissioning Calibration and Validation Campaign in Ottawa (ECALOT) was a dedicated airborne and surface-based campaign designed to support the calibration and validation of Level 1 and Level 2 products from the EarthCARE satellite mission. The campaign was conducted between …

This study examines the impact of inclusion of secondary ice production (SIP) parameterizations on the cloud microphysics and dynamics in numerical weather prediction (NWP) simulations under mid-latitude winter conditions. Hindcast mesoscale model simulations were performed for two flights from the 2019 In-Cloud …

Abstract The sensitivity of convective clouds to aerosols and their interactions with environment, combined with limited observational constraints in parameterizations, introduces significant uncertainties in atmospheric models. This study investigates the dependence of convective cloud microphysical properties on environmental conditions using a synergistic …
