Potential impact of stratospheric aerosol geoengineering on projected temperature and precipitation extremes in South Africa
… science researchers to mitigate climate change. Stratospheric Aerosol Injection (SAI) is one such option that is popularly debated as a potential measure to offset anthropogenic warming, while signatories of the Paris Agreement make efforts to reduce emissions and limit warming to 1.5°C. Most …

Cellulose nanocrystals as a candidate for solar geoengineering
… case, in pursuit of global warming mitigation. Stratospheric aerosol injection (SAI) and marine cloud brightening (MCB) are two methods of geoengineering that both aim to achieve solar radiation management, by reducing the net magnitude of radiation reaching the Earth’s surface. Solar radiation …

The influence of volcanic stratospheric aerosols on interannual global climate variations
… Oscillation (ENSO) by low-latitude volcanic stratospheric aerosols (Handler 1989). This mechanism is based on the normal global annual cycle resulting from the normal annual cycle in the distribution of incoming solar radiation. The presence of a volcanic stratospheric aerosol, which …

‘Opening up’ geoengineering appraisal: Deliberative Mapping of options for tackling climate change
… particular geoengineering proposals, principally stratospheric aerosol injection, through the exertion of power via framings. This thesis exhibits the findings of an ‘upstream’ participatory appraisal of geoengineering called Deliberative Mapping; an innovative analytic-deliberative methodology …

SOME MIDDLE ULTRAVIOLET RADIATIVE EFFECTS OF PARTICULATE POLLUTION IN THE STRATOSPHERE
The effect of increased stratospheric dust on the polarization and intensity of sunlight scattered by the terrestrial atmosphere in the spectral region near the ultraviolet transmission cutoff is examined. Particular interest is given to radiation reflected to space or transmitted to the surface in …

Application of neural networks to subseasonal to seasonal predictability in present and future climates
… under anthropogenic climate change and stratospheric aerosol injection (SAI). In particular, we explore subseasonal predictability and forecasts of opportunity changes under anthropogenic warming compared to a historical climate in the CESM2-LE. We then investigate how future seasonal …

THE PYROCONVECTIVE PATHWAY FOR STRATOSPHERIC WATER VAPOR AND AEROSOL
… that explores their convective dynamics, stratospheric plume characteristics and down-stream radiative effects. Satellite observations in conjunction with ground station data and radiative transfer models are used to quantify the impact that pyroCbs have on localized stratospheric aerosol …

Advanced Prototypes of the Aerosol Limb Imager
… past decades, the call for global monitoring of aerosol has amplified to better understand its role in climate change. The Canadian Space Agency has identified targeted program funding for mission development to address this call. The Aerosol Limb Imager, or ALI, is a candidate remote sensing …

Comparative aerosol studies based on multi-wavelength Raman LIDAR at Ny-Ålesund, Spitsbergen
… and the extreme radiative conditions. Clouds and aerosols as parts of the Arctic atmosphere play an important role in the radiation budget, which is, as yet, poorly quantified and understood. The LIDAR (Light Detection And Ranging) measurements presented in this PhD thesis contribute with …
