Planet Earth’s hyperspectral satellites will be called Tangiers, an endangered bird species

Planet has revealed new details of its upcoming hyperspectral constellation. The satellites will be named Tanager – a family of birds found in Central and South America – and will be designed to deliver ultra-high-spectrum data at a resolution of up to 30 meters with more than 400 spectral bands. Planet is building the constellation as part of a unique public-private partnership with the Carbon Mapper Alliance.

The first phase of this project is underway and includes the development of the first two satellites by Planet and NASA JPL, planned to be launched in 2023, A Planet spokesperson told Geospatial World via email.

Carbon Scheme Alliance

The Carbon Mapper Alliance is a non-profit organization created last year by like-minded organizations To monitor and help accelerate greenhouse gas emissions reductions. In addition to Planet, other partners include California, NASA’s Jet Propulsion Laboratory (NASA JPL), University of Arizona, Arizona State University (ASU), High Tide Foundation, and RMI.

“The Carbon Mapper program leverages pioneering expertise to fill data gaps related to the detection and estimation of methane and carbon dioxide emissions, advance understanding and scientific research for remote sensing to measure and monitor emissions, inform policy, and collaborate with stakeholders to develop mitigation solutions,” Carbon Mapper CEO Riley Doreen said in an email interview.

“As a member of the alliance, Planet manufactures hyperspectral satellites in conjunction with NASA’s Jet Propulsion Laboratory (JPL) using their leading edge sensing technology,” the Planet spokesperson added.

Arizona State University’s Center for Global Discovery and Conservation Science will also play a key role in the Carbon Map mission to conduct additional scientific research on hyperspectral applications.

“The alliance has devised a unique solution: a constellation of satellites with the high accuracy, agility, and wide area coverage needed to provide accurate information about the majority of the world’s highly emitting sources of methane and carbon dioxide,” Doreen said.

The consortium is currently implementing the first phase of the program that includes the development of the first two satellites by Planet and NASA JPL, planned for launch in 2023. This will accompany data analysis platforms, user engagement, and ongoing collaborative pilot projects to mitigate methane with aircraft in California and other US states.

He added that the program is designed to allow expansion to a larger constellation of satellites in the following years, with an end goal of tracking more than 80% of high-emitting methane and carbon dioxide sources on a daily to weekly basis.

Constellation details

The first hyperspectral satellite built by the Carbon Mapper Alliance will be used to monitor emissions of greenhouse gases including methane and carbon dioxide. Carbon Mapper will leverage this collected data to accelerate climate action by making highly emitting sources of methane and carbon dioxide visible to the public.

A statement from Planet Earth previously explained, “The Tanager is a family of birds that, like our planet, are under threat if we do not take substantive, data-backed action to protect ecosystems and resources.”

Planet, which operates the largest number of Earth-observing satellites, is looking at hyperspectral data provided by the Tanager satellites to complement and enhance its existing data set – medium-resolution (3-5 m) images from Doves, high-resolution (<1 m) SkySat and the Pelican receiver ) constellations.

“It is more important than ever that companies innovate and governments implement effective policies. Our hyperspectrum commercial offering, called Tanager, is looking to provide customers with data on methane and carbon dioxide emissions as well as dozens of other applications and environmental indicators needed,” the spokesperson added. to closely monitor the health of the planet’s lands and seas.” “Global leaders need targeted, actionable information as quickly as possible and our hyperspectral data can provide this critical layer of intelligence to help them assess and sustainably manage the state of the planet.”

Hyperspectral imaging provides a wide range of spectral insights because it splits the spectrum across many spectral bands, allowing analysts to review phenomena in many contrasting colors that typically exceed human visual perception.

Doreen explained that by continuously tracking source point emissions and identifying them at individual facilities that have a significant impact on total emissions, the data provided by the program is designed to accelerate emissions reduction while complementing other monitoring systems capable of tracking regional net emissions for more complete support. Accountability and direction of climate action by governments and businesses.

Furthermore, Doreen added that he hopes to see the importance of continuous monitoring of greenhouse gases take center stage as a way to inform science-based, near-term mitigation actions, and to reach a more pervasive audience beyond academic/science and policy/regulatory circles. “We also expect a focus on creative partnerships – such as the Carbon Mapper Alliance – which emerges because the urgency of the climate crisis demands more innovative, integrated and coordinated solutions,” he said.
