Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Land Models Likely Underestimate the Impact of Future Atmospheric Dryness on European Tree Growth

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Understanding how the land carbon sink will be altered by climate change is critical for projecting future atmospheric CO2 concentrations under different emission pathways in Earth System Models (ESMs). Most land models assume that woody growth, the main driver of land carbon storage, is driven by photosynthetic carbon supply.

Earthward Propagated Auroral Kilometric Radiation: Observations From Polar

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Auroral Kilometric Radiation (AKR), the strongest natural radio emission from Earth's magnetosphere, has been primarily observed in space. It is generally understood to propagate anti‐Earthward and be detected at large radial distances, while Earthward‐directed waves are thought to be blocked by the ionosphere. Surprisingly, AKR‐like emissions

Time‐Resolved SNOM via Phase‐Domain Sampling

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Time‐resolved scanning near‐field optical microscopy (tr‐SNOM) grants access to the dynamic dielectric function of monolayer and multilayer WS2, using visible wavelengths. In order to use a femtosecond laser with a repetition rate of 200 kHz, the signal is sampled and demodulated in the modulation phase domain, marking the first realization of tr‐SNOM ...

Anthropogenic Aerosols Influence Tropical Pacific Sea Surface Temperature Gradient Trends

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The tropical Pacific is warming more in the west than the east. This observed strengthening of the tropical Pacific east‐to‐west Sea Surface Temperature (SST) gradient is poorly reproduced in climate models—a prominent model bias with far reaching global impacts.
