1. Analysis of the Stratospheric Aerosol Load After the 2019 Raikoke Eruption
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : The stratospheric aerosol load after the eruption of Raikoke in 2019 have been analysed with satellite data from the CALIPSO satellite. The goal was to see how much the stratospheric aerosol load increased due to the Brewer Dobson circulation, and further, how this affected the stratospheric aerosol optical depth (AOD), and the corresponding radiative forcing (RF).

2. Cirrus Clouds; Study of Microphyscial Properties and Their Seasonal & Temperature Dependence in the Tropics and Mid-latitudes
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : Cirrus clouds are high-level ice clouds covering ≈ 30% of Earth’s surface. The cirrus clouds ice crystals can be formed by heterogeneous or homogeneous nucleation, where temperatures for heterogeneous nucleation was set to -38 - -30 °C and for homogeneous nucleation below -42 °C.

3. Use of Satellite Data for Prediction of Weather Impact on EO-Systems
Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : To predict the performance of an electro-optical sensor system (EO-system) requires taking the weather situation into consideration. The possibility to use weather data from satellites instead of ground – and flight stations has been investigated. LÄS MER
4. Retrieval of Cloud Top Pressure
Master-uppsats, Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Tekniska fakultetenSammanfattning : In this thesis the predictive models the multilayer perceptron and random forest are evaluated to predict cloud top pressure. The dataset used in this thesis contains brightness temperatures, reflectances and other useful variables to determine the cloud top pressure from the Advanced Very High Resolution Radiometer (AVHRR) instrument on the two satellites NOAA-17 and NOAA-18 during the time period 2006-2009.
