Sunlight incident on the Earth’s atmosphere is essential for life, and it driving force of a host photo-chemical environmental processes, such as radiative heating atmosphere. We report description application physical methodology relative to how an ensemble very low-cost sensors (with total cost <$20, less than 0.5% reference sensor) can be used provide wavelength resolved irradiance spectra with resolution 1 nm between 360–780 by calibrating against sensor using machine learning. These...

Temporal causal discovery is a crucial task aimed at uncovering the relations within time series data. The latest temporal methods usually train deep learning models on prediction tasks to uncover causality between series. They capture by analyzing parameters of some components trained models, e.g., attention weights and convolution weights. However, this an incomplete mapping process from model fails investigate other components, fully connected layers activation functions, that are also...
