1. Seasonal Variability of Ice Nucleating Particles (INP) in Southern Sweden
University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskapAbstract : Cloud ice crystals are formed by ice-nucleating particles (INPs). The micro-physical properties of clouds, precipitation formation and the life cycle of clouds are strongly influenced by the presence or absence of ice. Therefore knowledge of atmospheric INP concentrations is crucial to improve weather forecasting and climate projections. READ MORE

2. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. READ MORE

3. Exploring Diversity of Spectral Data in Cloud Detection with Machine Learning Methods : Contribution of Near Infrared band in improving cloud detection in winter images
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Cloud detection on satellite imagery is an essential pre-processing step for several remote sensing applications. In general, machine learning based methods for cloud detection perform well, especially the ones based on deep learning as they consider both spatial and spectral features of the input image.

4. Fragmentation in graupel snow collisions
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Aircraft observations of precipitating clouds with cloud top temperatures higher than -38°C have revealed that Secondary Ice Production (SIP) is responsible for presence of majority of ice particles. One such SIP mechanism is fragmentation via collisions between ice particles. READ MORE

5. Snow-graupel collisions in clouds: a newly derived formulation for breakup of single crystals
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The observed and well-known discrepancy between concentrations of ice nucleating particles in the environment and the concentrations of ice particles in clouds show that there are additional ‘secondary’ processes enhancing the concentrations of ice particles. In present-day modelling of weather and climate, such processes are mostly overlooked and thus a cause for uncertainty. READ MORE
