Abstract

The overall goal of the proposed research is to improve avalanche forecasting by developing a decision support tool that provides data-driven automated predictions of avalanche hazard. We hypothesise that by applying modern data science and machine learning methods on the diverse (in time and space) snow and avalanche data, snow avalanche hazard can automatically be forecast – with at least the accuracy of present experience-based forecasts.

description

Problem:

Operational avalanche forecasting – issuing warnings to the general public – is still by and large an experienced-based process. The lack of appropriate numerical or statistical methods has hence prevented:

  1. Knowledge extraction required for a sustainable operation.
  2. Numerical forecasting i.e. data-driven decision support crucially important for consistent and objective forecasts.

Proposed approach:

  • Develop statistical learning techniques for support decision making in snow and avalanche disciplines
  • Develop data-driven probabilistic methods from multi-year snow and avalanche datasets to support operational avalanche forecasting

Impact:

  • Assist avalanche forecasters and operational decision support tools with:
  • Predictive methods of avalanche danger level (a score from 1 to 5)
  • Predictive models of avalanche danger type (the type of likely avalanches)
  • A better understanding of the spatio-temporal relationships between measurement stations, and potentially improve the monitoring network

Climate-smart agriculture in sub-Saharan Africa: optimizing nitrogen fertilization with data science

Food insecurity in sub-Saharan Africa is widespread, with crop yields much lower than in many developed regions. The project aims to use laser spectroscopy to measure fluxes and isotopic composition of N2O from maize and potato crops subjected to a range of fertilization levels.
