Detecting and attributing climate change effects on vegetation: Australia as a test case

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Diverse Prairie Mixtures Stabilize Biomass Yields for Sustainable Aviation Fuel Production

PLANTS, PEOPLE, PLANET, EarlyView.
Meeting global demand for sustainable aviation fuel will require the additional production of vast quantities of plant biomass, which does not compete with food production or degrade sensitive ecosystems. Our multisite experiment shows that sowing diverse native prairie seed mixes—and managing them without intensive inputs—yields a more reliable ...

Efficacy evaluation of pneumatic solid set canopy delivery system to control powdery mildew (Erysiphe necator) in Washington vineyards

Pest Management Science, EarlyView.
The findings of this study indicate that powdery mildew control achieved with the pneumatic solid set canopy delivery system (PSD‐SSCDS) was comparable with that of a conventional airblast sprayer. These results highlight the PSD‐SSCDS as a promising alternative spray technology. Abstract BACKGROUND In this study, a previously optimized pneumatic spray

All‐sky assimilation impacts of the Tomorrow.io microwave sounder constellation on global weather forecasts

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Key Findings: An assimilation methodology is established for the Tomorrow.io microwave sounder (TMS) flying on CubeSats in sun‐synchronous and inclined orbits, and in all cloud scenes. The TMS has a significant impact on weather forecast lead times up to 3 days in the Tropics in a research‐quality numerical weather prediction setting, and yields water ...

Ultra Wide Swath Sea interferometric multibeam echo sounder with sea bottom imaging system.

, 1990
The SIMRAD EM12 is a new full ocean depth multibeam echo sounder, operating at 13 kHz. By use of interferometric signal processing techniques it will achieve an ultra wide swath geometry of 150 degrees, corresponding to 7.5 times the depth of water.

Sliding Doors: Frame Uptake and Rejection by Learners in a Museum‐Based Climate Learning Experience

Science Education, EarlyView.
ABSTRACT Science education efforts that support public understanding of modern climate change are critically needed. However, implementing climate‐related learning experiences can be challenging, as public audiences tend to experience a wide range of understandings of and emotions around the issue. In light of these challenges, many scholars have posed
