2. Effects of stratospheric wildfire smoke on ozone depleting substances and ozone levels in the northern midlatitudes
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/KärnfysikAbstract : The goal of this project was to examine whether there are correlations between recent wildfires in the northern hemisphere and stratospheric ozone anomalies in the midlatitudes following the creation of ozone depleting substances. To achieve this goal, data from the Aura satellite's Microwave Limb Sounder instrument was used and processed with self-written Python scripts. READ MORE

3. Studies on the application of gas cooling as used by firefighters
University essay from Lunds universitet/Avdelningen för BrandteknikAbstract : Gas cooling is a technique used by firefighters to create a safer work environment inside a compartment fire. By spraying water into the smoke layer, the smoke layer temperature will decrease significantly. Next to the lower temperature, the flammability of the smoke layer will also decrease. READ MORE

4. Thermal Exposure Caused by the Smoke Gas Layer in Pre-flashover Fires : A Two-zone Model Approach
University essay from Luleå tekniska universitet/Byggkonstruktion och brandAbstract : A pre-flashover fire is very different from a post-flashover fire. The main difference is that in a pre-flashover fire the gas temperature and the radiation temperature differ. One thing that makes it a lot different is that the thermal exposure induced by a pre-flashover fire is largely affected by the smoke gas layer. READ MORE
