The Earth ILLumination Foundations for Citizen Science ‘ELLF’ project engages society members on the ground, with their own data plus from spacecraft above, to untangle two climate parameters during three years of unique natural environmental events: new moon phases, two total solar eclipses and a special type of cloud that forms during summers in each hemisphere. With those climate parameters, the citizen scientists in Northern Europe with active partners in Australia and the USA, will be invited to participate in the ELLF’s scientific endeavor. We will learn how close are humans to the 'tipping point', when the climate has changed too much to return. The project’s ELLF 3U CubeSat carrying the hyperspectral imager payload will drive the climate science, the society’s interest, and gain industry confidence to initiate and carry conversations about the seriousness of the climate urgency.
