We have now seen the first results from all 4 EarthCARE’s instruments: and let me tell you, they are truly promising! The latest ones to come in are from the satellite’s LIDAR. The profiles from the atmospheric lidar come exactly as we had anticipated, after the instrument has been through its routine decontamination and calibration processes. The atmospheric lidar brings us completely new insight into the vertical distribution of clouds and aerosols and, together with the other instruments, puts us on course to gaining new scientific understanding into Earth’s energy balance.

  • This image, from the atmospheric lidar on 2 August 2024, is a strip over Africa. As well as high convection clouds, the most prominent feature here is a very dense layer of aerosols from biomass burning, which is common at this time of the year over large parts of the continent. These fires are mostly ignited to remove forest or last year’s crop growth and make way for cleared agricultural land.
  • This profile, captured on 4 August by the atmospheric lidar, is a strip over North America. Here, the presence of tropical storm Debby is clear to see over the Gulf of Mexico, as are large convective clouds further north. As these clouds are optically very thick, as can be seen in the multispectral imager information, the lidar captures details of the cloud tops, but cannot see below them. Additionally, a striking red layer of aerosols is visible in the central part of the profile. These aerosols have been carried by the wind from forest fires that have been burning for a number of weeks in several regions of Canada. Smoke from forest fires plays a complex role in climate change, with both immediate and long-term effects that can disrupt weather patterns, accelerate global warming, as well as impact air quality when close to the ground.
  • This profile, captured on 3 August 2024 by the atmospheric lidar over the mid-Atlantic, is particularly rich in information. High-altitude cirrus clouds, deep convection clouds and low, thin clouds all feature in this profile. There are also two different types of aerosol: marine aerosols that include salt spray from the ocean, and a thick layer of dust blowing off the African Sahara desert. Understanding the complex relationship of these clouds and aerosols in the Tropics is fundamental to understanding Earth’s climate and how it will change.
  • This image from the atmospheric lidar, captured on 2 August 2024, offers a profile of polar stratospheric clouds over Antarctica. The grey strip below, as featured in all of the images, is the corresponding area captured in the infrared by EarthCARE’s multispectral imager instrument, which gives natural visual context to all of the instruments’ data. Polar stratospheric clouds are crucial contributors to the depletion of stratospheric ozone during winter and spring. These clouds serve as surfaces for chemical reactions that generate chlorine free-radicals, which actively destroy ozone molecules in the stratosphere. This process is a key factor in the formation of the infamous ozone hole over Antarctica. The jagged shape of the clouds in the centre-right is likely to be caused by gravity waves.

A space lidar is not a simple instrument... but what it brings to Earth Science is definitely worth the efforts. Look at these amazing details on how atmosphere is structured over various forcing conditions.. After Aeolus success, Europe is leading the way, again! Thank you European Space Agency - ESA , thank you to my former team at Airbus Defence and Space, thank you to the science team. ViGoRouS Project Evaluation

Fantastic news about EarthCARE's LIDAR results! It's exciting to see how this technology can enhance our understanding of atmospheric composition and cloud dynamics. Integrating data from all four instruments will undoubtedly provide a more comprehensive picture of Earth's climate systems. This holistic approach is crucial for developing more accurate climate models and informing global policy decisions. Looking forward to seeing how these insights translate into actionable strategies for mitigating climate change!
