Global warming is amplified in the Arctic. However, numerical models struggle to represent key processes that determine Arctic weather and climate. To collect data that help to constrain the models, the HALO–(𝒜𝒞)3 aircraft campaign was conduc

Publikováno v: Atmospheric Measurement Techniques, Vol 17, Pp 3863-3881 (2024)

Mixed-phase clouds are not well represented in climate and weather forecasting models, due to a lack of the key processes controlling their life cycle. Developing methods to study these clouds is therefore essential, despite the complexity of mixed-p

Publikováno v: Atmospheric Measurement Techniques, Vol 15, Pp 3969-3999 (2022)

Ice growth processes within clouds affect the type and amount of precipitation. Hence, the importance of an accurate representation of ice microphysics in numerical weather and numerical climate models has been confirmed by several studies. To better

Publikováno v: Atmospheric Measurement Techniques, Vol 15, Pp 677-699 (2022)

Accurate measurements of ice hydrometeors are required to improve the representation of clouds and precipitation in weather and climate models. In this study, a newly developed, synergistic retrieval algorithm that combines radar with passive millime
