MicroCarb’s First Glimpse of Earth Unlocks Amazon Climate Insights
The Franco-UK MicroCarb satellite has successfully captured its first view of Earth, achieving a key milestone less than five weeks after launch on 25 July. Its early observations, taken on 28 August, focused on the Amazon Basin, a region critical to regulating the planet’s carbon cycle but notoriously difficult to study.
Breaking Through the Amazon’s Challenges
The Amazon is one of the most complex regions for satellite monitoring. Dense forests absorb light, heavy cloud cover often obscures the surface, and the South Atlantic Magnetic Anomaly complicates readings. Despite these hurdles, MicroCarb’s instruments delivered data that matched pre-launch expectations.
The satellite’s onboard imager managed to detect cloud-free patches within the rainforest, picking out urban areas and the contrasting agricultural and forested landscapes around them. At the same time, the spectrometer recorded clear signatures of both carbon dioxide and oxygen by analysing reflected sunlight. This marks an essential step towards delivering accurate atmospheric CO₂ measurements from space.
“A Clear Win” for the Partnership
Professor Paul Palmer, UK Lead MicroCarb Scientist and Science Director at the National Centre for Earth Observation, expressed his excitement at the satellite’s swift success:
“It’s remarkable to see such high-quality ‘first light’ data delivered so quickly following the MicroCarb launch. It’s a clear win for the Franco-UK partnership, and I can’t wait to dive into the data and start the science.”
From Calibration to Climate Insights
To ensure accuracy, the data was checked against both pre-launch characterisation tests, including thermal vacuum trials completed in 2022, and in-flight calibrations such as dark current and solar reference measurements. Comparisons with external datasets, including Sentinel-2 imagery and advanced radiative transfer models, confirmed the instruments are working within design limits.
The next stage for the mission team will be fine-tuning the calibration and processing algorithms. This will allow MicroCarb to deliver high-precision measurements of atmospheric CO₂, providing new insight into how regions like the Amazon help regulate Earth’s climate.
