Cairo, big data on environmental change services

Appearing at the CNRS stand at the Vivatech exhibition in Paris, the Kayrros company develops solutions for energy resources and climate risk monitoring.

Detect, analyze and monitor the amount of carbon isolated by global crude oil reserves, methane leaks or planetary forests in almost real time: Founded in 2016, Cairos relies on public data, satellite imagery or data collected on social networks to take precise action. Purpose: To guide the policies of industrialists and the public on environmental change.

Innovative solutions for energy resource monitoring

The name is a clear reference to the little Greek god DanawalaAppropriate occasion, Cairos. ” Kayrros was born out of a global observation of the limitations and flaws of traditional information in the energy sector. Transparency and reliable information were needed, and to fill an information gap. It was a fitting moment; We have taken this opportunity “Antoine Half, an analyst and co-founder of Young Shoot, is an expert in the energy market. To do this, Cairo relies heavily on a constellation of Earth observation satellites, the Sentinel, which was deployed as part of the Copernicus program.European Space Agency (ESA). This constellation, which has grown over the last few years, scans the Earth almost daily: radar images, observations of information on the structure of plants, land cover and optical images of water.Atmospheric and greenhouse gases, high precision measurementSea level rise …

In 2016, data is poured. We have a way to process them on a scale to create macroeconomic statistics, especially thanks to advances in AI in the interpretation of images. Alexander D’Asprement, director of research at CNRS in the computer science department at Ecole Normal Superior (DI ENS) and one of the company’s five co-founders, explained. Working closely with research laboratories such as the Borelli Center for Satellite Data Processing and Interpretation and the Climate and Environmental Sciences Laboratory (LSCE) for much more on climate issues.Essential to their technology is to retrieve these images, process them, calibrate them and feed them by algorithms. ” In other words, they are grafted with algorithms that measure a certain amount of basic quantitative macroeconomic data. “, Researcher continues.

Methane leak tracking around the world

We want to develop measuring tools for applications that do not yet have an established use. Until very recently For example, there were many difficulties in detecting, tracking, and quantifying methane leaks on a planetary scale. “, Teaming up with LSCE researchers, they systematically analyzed thousands of images produced daily over two years by ESA’s Sentinel-5P satellite, mapping 1,800 methane plumes around the world, of which 1,200 were rewarded. Done.ExploitationHydrocarbons – production and transportation. Accidental releases or releases related to maintenance operations that lead to very important leaks and whose levels were largely underestimated: 8 million tons per year, mainly in a few countries.

The map shows a sample of unusual methane concentrations in 2019 Identifying the size and color of the circles indicates the size and intensity of the plume The redder the color, the higher the density of the methane plum.

But that is not the caseThat submerged partIceberg: Satellite nSystematically able to detect only the most massive plumes, which have the most breaks. Fighting this loophole could save billions of euros, but above all it represents a simple and inexpensive way to limit global warming. ” This work also demonstrates the need to introduce a reliable atmospheric monitoring system that will allow for both systematic monitoring of emissions and local targeting of actions. Companies and states have combined the need to demonstrate a specific climate responsibility. But these declarations of intent are difficult to verify. There is a real need for transparency, independence and standards. The data we use is universal and freely accessible: the reproducibility of our research is what is needed to reach higher levels of environmental change. “, Adds analysis.

Estimation of carbon sequestration by plants

Cairos European SMOS Satellite (S)Humidity of oil and salinity of sea) Which gives a fairly accurate picture of plants, or GEDI satellites (Global Ecosystem Dynamics Investigation) Which makes it possible to measure the height of the tree and determine the size of the forest. ” We now want to monitor CO emissions in near real time2 And the amount of carbon isolated by plants 6, Alexander D’Asprement mentions. This is to shed light on the strategies implemented in the fight against climate change.

The map shows the evolution of biomass above ground globally in two quarters. The value corresponding to each pixel is calculated as the maximum in a sliding window of one year.

The REDD + process, for example, is a UN-sponsored initiative aimed at reducing CO2 emissions.2 From deforestation and deforestation. It depends on the way it is implemented, especially for developing countries based on financial incentives – and indirectly linked to the carbon market. ” The price of carbon per ton in the European market is much higher than the price of forest seizures. This difference is explained by the uncertainty that hangs over afforestation projects and punishes these actors, who are often developing countries. “The reason: the latter’s data is fragmented,” the researcher explained. The aim is to provide more transparency and precision in order to not only allow better pay for emerging countries, but also to secure these processes.. A

And now? Cairo, which now has more than 150 employees, has raised just 40 million euros. A new contribution they will make to market and accelerate the marketing of their equipment, the first of which makes it possible to estimate variations in the world’s crude oil reserves – 10,000 tanks from which they cut volume from radar images – and aims to bring some transparency to the occasional opaque market. . ” We have a very French bias which includes very good products but forget to sell them Alexander D’Aspremont smiled. ” Vivatech will be an opportunity to meet students interested in our projects related to researchers, laboratories, climate but also to establish and strengthen new partnerships “, He concludes. 3
