Spectacular increase in the deuterium/hydrogen ratio in Venus' atmosphere

Researchers discovered an unexpected increase in H2O and HDO concentrations in Venus' mesosphere, with the HDO/H2O ratio rising 120 times higher than expected. This finding suggests that solar radiation broke down water isotopologues, producing hydrogen atoms that escape into space, leading to deuterium enrichment.

Climate change is making night-shining clouds more visible

Researchers found that increased greenhouse gas emissions have led to a significant increase in noctilucent cloud formation and visibility. The study suggests that human-caused climate change is affecting the middle atmosphere and making these clouds more visible.

NASA advances world's first spaceborne sodium lidar

Scientists at NASA's Goddard Space Flight Center are developing the world's first spaceborne sodium lidar to illuminate the complex relationship between Earth's chemistry and mesosphere dynamics. The instrument will provide higher-resolution data on the small-scale dynamics occurring in the upper atmosphere.

Clouds, clouds, burning bright

Researchers use noctilucent clouds as a proxy for atmospheric temperatures, revealing changes in the mesosphere that can affect global weather systems. The clouds' annual formation is influenced by wind circulation patterns between hemispheres.

NASA extends TIMED mission for fourth time

The NASA Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) mission has been extended for the fourth time to study the upper atmosphere. The mission will focus on differentiating between human-induced and naturally occurring changes in this atmospheric region, allowing scientists to understand long-term trends.

New thinking needed on atmospheric physics, study suggests

Researchers collected sprite data during a balloon campaign to study the electromagnetic signature of lightning strokes that produce sprites. The results indicate that negative cloud to ground strokes produce sprite halos seven times more often than positive strokes, suggesting an energy imbalance in the mesosphere.
