AI to boost understanding of Earth

Berlin: Artificial intelligence (AI) can substantially improve our understanding of the climate and the Earth system, according to a study. Complex dynamic processes such as hurricanes, fire propagation, and vegetation dynamics can be better described with the help of AI, said researchers from the Friedrich Schiller University Jena (FSU) in Germany.

As a result, climate and Earth system models will be improved, with new models combining AI and physical modelling, according to the study published in the journal Nature. In the past decades mainly static attributes have been investigated using machine learning approaches, such as the distribution of soil properties from the local to the global scale.

For some time now, it has been possible to tackle more dynamic processes by using more sophisticated deep learning techniques. This allows to quantify the global photosynthesis on land with simultaneous consideration of seasonal and short term variations.

“From a plethora of sensors, a deluge of Earth system data has become available, but so far we have been lagging behind in analysis and interpretation,” said Markus Reichstein, managing director of the Max Planck Institute for Biogeochemistry. “This is where deep learning techniques become a promising tool, beyond the classical machine learning applications such as image recognition, natural language processing or AlphaGo,” said Joachim Denzler from the Friedrich Schiller University Jena (FSU). Examples for application are extreme events such as fire spreads or hurricanes, which are very complex processes influenced by local conditions but also by their temporal and spatial context.

This also applies to atmospheric and ocean transport, soil movement, and vegetation dynamics, some of the classic topics of Earth system science, researchers said. All data-driven and statistical approaches do not guarantee physical consistency per se, are highly dependent on data quality.
