Short summary
This research aimed to improve our understanding of cloud structure using spaceborne measurements. The study applied an optimal estimation method to determine how cloud droplet sizes change with height, using satellite data and coincident aircraft measurements for validation. It found that current space-borne spectrometers lack the accuracy to fully resolve this vertical structure, but upcoming instruments like CLARREO (Climate Absolute Radiance and Refractivity Earth Observatory) Pathfinder will significantly enhance this capability.

This work presents heating rates derived from aircraft observations from the 2016 and 2017 field campaigns of ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS). We separate the total heating rates into aerosol and gas (primarily water vapor) absorption and explore some of the co-variability of heating rate profiles and their primary drivers, leading to the development of a new concept: the heating rate efficiency (HRE; the heating rate per unit aerosol extinction).

Short summary
Continuous monitoring of Earth's energy balance from space is essential for understanding climate change. Beyond the next planned mission, continuity of these observations remains uncertain. Earth-viewing observations from a CubeSat designed to observe the Sun were compared to established Earth-observing instruments, showing close agreement. Results suggest CubeSats could reduce the risk of gaps in long-term records and that solar-monitoring instruments could be designed to observe Earth, too.
Continuous monitoring of Earth's energy balance from space is essential for understanding...
