Launched in Might 2024, ESA’s EarthCARE satellite tv for pc is nearing the tip of its commissioning part with the discharge of its first information on clouds and aerosols anticipated early subsequent yr. Within the meantime, a global workforce of scientists has discovered an revolutionary means of making use of synthetic intelligence to different satellite tv for pc information to yield 3D profiles of clouds.
That is significantly information for these eagerly awaiting information from EarthCARE of their quest to advance local weather science.
Clouds play a vital position in Earth’s local weather system by reflecting daylight again into area, often called the albedo impact, and by trapping warmth radiating from Earth’s floor, a part of the greenhouse impact.
For instance, excessive, skinny clouds are inclined to heat the environment as a result of a excessive proportion of power from the Solar can move by and they’re additionally environment friendly at trapping warmth radiating from Earth’s floor. Low, thick clouds however, are inclined to have a cooling impact as they mirror a excessive proportion of the incoming daylight again out to area.
Whereas scientists know that clouds play a particularly an essential position in each cooling and warming our environment, there stays uncertainty with regards to accounting for the precise affect they’ve on Earth’s power stability.
Furthermore, given the continued local weather disaster, there may be an pressing want to grasp if modifications to clouds will exert an total cooling or warming impact sooner or later.
World, realtime 3D cloud information would assist scale back these uncertainties, bettering local weather predictions and serving to decision-making.
During the last a long time NASA’s CloudSat mission has offered beneficial vertical cloud profiles however was restricted by rare revisits. Geostationary missions, equivalent to Europe’s Meteosat Second Technology (MSG), however, take photos over Europe each 15 minutes, however solely get hold of a ‘top-down’ view, with out immediately probing cloud profiles.
Utilizing superior machine studying strategies, a global workforce of scientists, coordinated by ESA Φ-lab and FDL Europe, has leveraged superior machine studying strategies to develop a way for producing ‘3D cloud profiles in all places, abruptly’.
Of their proof-of-concept examine, they analysed a yr’s value of archived CloudSat and MSG information from 2010. The ensuing paper, which was introduced this week on the Neural Info Processing Techniques convention in Canada, demonstrates how synthetic intelligence can extract new insights from present satellite tv for pc observations.
Anna Jungbluth from ESA’s Local weather and Lengthy-Time period Motion Division, defined, “We fastidiously aligned the measured CloudSat profiles with photos from MSG. This helped us perceive how the ‘view from prime’ and the corresponding cloud profiles had been associated.
“We then skilled machine studying fashions to grasp this mapping and derive cloud profiles from the 2D imagery. This allowed us to increase the CloudSat profiles in each area and time.”
The mixing of cutting-edge AI strategies and Earth commentary experience exemplifies how revolutionary approaches can improve the worth of present and future satellite tv for pc missions.
The primary animation within the physique of this text reveals how AI was used on an MSG picture (infrared channel) with a co-aligned CloudSat monitor. The mannequin learns from the restricted overlap of the MSG picture and CloudSat monitor, and is ready to prolong the vertical cloud profile in area.
The second animation (additionally featured within the prime banner) reveals how after the mannequin is skilled, predictions may be made for MSG photos with out corresponding CloudSat tracks, and 3D cloud maps may be created throughout area and time.
Michael Eisinger, from the EarthCARE venture workforce and likewise from ESA’s Local weather and Lengthy-Time period Motion Division, added, “EarthCARE has already given us some very promising preliminary information and we predict nice science from this new satellite tv for pc mission. Our work producing these 3D cloud profiles lays the muse for exploiting EarthCARE from a unique angle.
“These new AI strategies promise to maximise EarthCARE’s scientific potential and combine its information into complete world fashions that may push the boundaries of local weather science.”
Keep tuned for extra updates as EarthCARE information is harnessed to refine and increase this pioneering strategy.
