GHGSat unveils free global methane map

SAN FRANCISCO – GHGSat unveiled a free map Oct. 21 exhibiting common weekly methane concentrations world wide at a decision of roughly two kilometers per pixel.

GHGSat’s map, known as Pulse, exhibits modifications in methane concentrations measured in elements per million or elements per billion for every pixel throughout the yr.

“We hope that Pulse will elevate consciousness, stimulate dialogue and lead folks to ask questions,” Stephane Germain, GHGSat founder and CEO, stated throughout a press briefing. “Pulse is intentionally designed to not establish hotspots or to attribute emissions to any explicit supply. If folks need extra element, we provide 25-meter imagery on the market.”

Firms and authorities businesses additionally rent GHGSat to pinpoint methane sources.

“If folks need to see hotspots or discover emission sources, we provide these companies on the market as effectively,” Germain stated.

GHGSat detects and measures world greenhouse gasoline emissions with two satellites: Claire, launched in 2016, and Iris, launched in September. The Toronto-based firm plans to launch one other methane satellite tv for pc, Hugo, in December on a SpaceX Falcon 9 rideshare mission. By 2022, GHGSat plans to function 10 satellites.

The corporate wants 10 satellites to offer clients with “common measurements for all their services in these areas of manufacturing,” Germain stated.

To create Pulse, GHGSat mixed information from its personal satellites with information gathered by European House Company, NASA and Japan Aerospace Exploration Company satellites.

The federal government “satellites which might be 100 occasions greater and costlier than ours, however they benefit from with the ability to generate information for the complete planet on daily basis,” Germain stated. “They do it in a coarser decision. So we mixed their information with ours as a way to get these maps and have that form of accuracy that all of us need in particular areas.”

Sarah Gallagher, Canadian House Company science advisor to the president, stated Pulse will assist goal efforts to cut back methane emissions.

“Methane has a worldwide warming potential that’s 84 occasions that of carbon dioxide,” Gallagher stated throughout the press briefing. “We have to know when, the place and the way methane goes into the environment. Lowering methane emissions is a crucial instrument for addressing local weather change.”

GHGSat created the primary technology of Pulse with information from its first satellite tv for pc Claire and plans to incorporate Iris information in future variations.

“We’re already engaged on the following technology which is able to present the quantity of methane per day emitted or absorbed per pixel,” Germain stated.

GHGSat introduced plans to map methane emissions world wide on the World Financial Discussion board in January in Davos, Switzerland. On the time, GHGSat stated it will launch the map in time for the United Nations Local weather Change Convention, the twenty sixth Convention of Events, initially scheduled to start Nov. 9 in Glasgow, Scotland. Due to the COVID-19 pandemic, the Convention of Events has been delayed till November 2021.

“It’s being delayed like many issues this yr,” Germain stated. “There’ll nonetheless be a digital occasion this yr and we needed to honor that dedication.”
