Exact Moonlight Measurements Could Aid Earth-Observing Missions

Ilima Loomis, Science Writer by Ilima Loomis 27 November 20172 November 2021

A new telescope’s unprecedented study of subtle variations in lunar light could finally give Earth-facing satellites a common reference point for their observations.

We may be overestimating how reflective Earth is—and underestimating how much energy the planet’s ice sheets are absorbing.

On-the-Ground Measurements Overestimate Earth’s Albedo

by David Shultz 18 August 20176 July 2022

Weather stations can be used to calibrate and validate albedo measurements from satellites, but they fail to account for variability across landscapes, overestimating how reflective our planet is.

A Date Under the Stars? Maybe Not with Aerosol Injection

by S. McQuate 14 December 20163 February 2022

Injecting aerosols into the atmosphere on purpose could help cool Earth, but new research shows that it could also make the night sky brighter and negatively affect human health.

Aerosols Make Cumulus Clouds Brighter but Shorter Lived

by David Shultz 10 February 20163 February 2022

Computer simulations show that although adding aerosol particles to clouds can make them more reflective, the cooling effect from clouds is largely counterbalanced by a reduction in overall cloud cover.

Satellites Track Chlorophyll Fluorescence to Monitor Drought

by L. Strelich 3 February 201614 March 2023

New satellite observations show connection between solar-induced chlorophyll fluorescence and soil moisture—a key mechanism behind drought onset.
