Data and scripts for "Unraveling secondary ice production in winter orographic clouds through a synergy of in-situ observations, remote sensing and modeling"
Athanasios Nenes, Alexis Berne, Satoshi Takahama, Georgia Sotiropoulou, Paraskevi Georgakaki, Romanos Foskinis, Kunfeng Gao, Anne-Claire Marie Billault--Roux
This repository contains field observations and processed data from the Weather Research and Forecasting (WRF) model simulations and the Cloud Resolving Model Radar Simulator (CR-SIM), alongside scripts designed to reproduce the figures presented in the pa ...
Zenodo2024Unraveling ice multiplication in winter orographic clouds via in-situ observations, remote sensing and modeling
Athanasios Nenes, Alexis Berne, Satoshi Takahama, Georgia Sotiropoulou, Paraskevi Georgakaki, Romanos Foskinis, Kunfeng Gao, Anne-Claire Marie Billault--Roux
Recent years have shown that secondary ice production (SIP) is ubiquitous, affecting all clouds from polar to tropical regions. SIP is not described well in models and may explain biases in warm mixed-phase cloud ice content and structure. Through modeling ...
Nature Portfolio2024Simulations of primary and secondary ice production during an Arctic mixed-phase cloud case from the Ny-Ålesund Aerosol Cloud Experiment (NASCENT) campaign
Georgia Sotiropoulou, Paraskevi Georgakaki
The representation of Arctic clouds and their phase distributions, i.e., the amount of ice and supercooled water, influences predictions of future Arctic warming. Therefore, it is essential that cloud phase is correctly captured by models in order to accur ...
Copernicus Gesellschaft Mbh2024Unraveling secondary ice production in winter orographic clouds through a synergy of in-situ observations, remote sensing and modeling
Athanasios Nenes, Alexis Berne, Satoshi Takahama, Georgia Sotiropoulou, Paraskevi Georgakaki, Romanos Foskinis, Kunfeng Gao, Anne-Claire Marie Billault--Roux
Recent years have shown that secondary ice production (SIP) is ubiquitous, affecting all clouds from polar to tropical regions. SIP is not described well in models and for this may vastly underpredict ice crystal number concentrations in warm mixed-phase c ...
2023Secondary ice production in NorESM2 climate model: quantifying the impact on Arctic clouds
Athanasios Nenes, Georgia Sotiropoulou
Arctic clouds are among the largest sources of uncertainty in predictions of Arctic weather and climate. This is mainly due to errors in the representation of the cloud thermodynamic phase and the associated radiative impacts, which largely depends on the ...
Copernicus2021The relative contribution of secondary ice processes in Alpine mixed-phase clouds
Athanasios Nenes, Alexis Berne, Georgia Sotiropoulou, Paraskevi Georgakaki, Etienne Gabriel Henri Vignon
In-situ observations of mixed-phase clouds (MPCs) forming over mountain tops regularly reveal that ice crystal number concentrations (ICNCs) are orders of magnitude higher than ice-nucleating particle concentrations. This discrepancy has often been attribu ...
2021The impact of secondary ice processes on orographic mixed-phase clouds
Athanasios Nenes, Alexis Berne, Georgia Sotiropoulou, Paraskevi Georgakaki, Etienne Gabriel Henri Vignon
Ground based and airborne observations of orographic mixed-phase clouds (MPCs) forming over mountain top research stations have long reported a discrepancy between the measured ice crystal number concentrations (ICNCs) and the concentration of ice nucleati ...
2021Quantifying the Impact of Primary vs Secondary Ice Production on Arctic Clouds
Athanasios Nenes, Georgia Sotiropoulou
Ice formation remains among the most poorly understood and hence poorly represented cloud processes in climate models. Primary ice production (PIP) has been recognized as a key process for the correct representation of the modeled cloud feedbacks; secondar ...

Athanasios Nenes, Georgia Sotiropoulou
Mixed-phase clouds in polar regions play a crucial role in surface ice melting. To accurately predict their radiative impact in climate models, an accurate representation of their microphysical structure is required. However, cloud ice content is generally ...
