Abstract

fetched live from OpenAlex

Understanding the properties of aerosols under stratospheric conditions is of particular importance for applications in solar radiation management. Aerosols have the potential to influence the Earth's radiative balance by stratospheric aerosol injection (SAI), which increases albedo and enhances the reflection of solar radiation back into space. By investigating the optical properties of various aerosol types under different environmental conditions, we aim to explore materials for SAI that exhibit albedo-enhancing potential while maintaining stability in the stratosphere.We have developed an optical trapping system with counter-propagating laser beams coupled with cavity-enhanced Raman spectroscopy to monitor the physical properties of single aerosol particles. This technique, supported by bulk measurements, enables us to determine the wavelength-dependent refractive index under different temperature and relative humidity parameters. Our specially designed optical system allows for rapid changes in temperature and relative humidity using a movable platform while maintaining a stable gradient within the cell reproducing stratospheric conditions. Our findings contribute to a deeper understanding of the suitability of aerosols for climate mitigation strategy and the broader effects of their deployment.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
