Answer to Bottleneck

Previously

In the article, “AI for Earth observation and numerical weather prediction”, by Boukabara, the community identified the need to boost the growth of data refinement technology. Furthermore, based on the trend and performances observed in other disciplines with similar challenges, Boukabara suggested a strong candidate for the solution: AI. The research by Professor Bue and his colleagues support Boukabara’s argument.

Spectroscopy

The spectroscopy is essentially the study of light crossed with chemistry. When a chemical is treated with certain stress, such as heat, it emits light. This is like a finger print to a person: each chemical emits light with a specific wavelength. The spectroscopy is a branch of science that studies the light wave to the chemical that is associated with it. It is widely used to identify the chemical constituent of an unknown compound or a distant star system, among other things. It is also used to understand the chemical composition of a given segment of air on Earth, but this has proven to be computationally too expensive to perform extensively (Bue et al, 2019).

The Research

Professor Bue and his collogues devised a way to replace the computationally expensive method, called Radiative Transfer Models (RTM) with comparably inexpensive method of emulating it of machine learning. The new method is powered by machine learning, and it has shown comparably accurate results to the traditional counterpart. This means that the use of spectroscopy on satellite images has become far more scalable, increasing the scientists’ capability to distill useful information from the image data. This is certainly a strong step towards answering Boukabara’s urge to the society.
