Cornell Expands Wildfire Smoke Sensor Network for New York

When Canadian wildfire smoke covered New York this summer, nearly half of the state's counties lacked data on air quality. A task group led by Fellow Alistair Hayden (Veterinary College) installed sensors in these counties, allowing state and federal agencies to observe smoke plumes in real time, collect data, and issue timely alerts to the public.

“In talking to officials from around the state, it quickly bubbled up that many upstate communities had no data about their air quality,” Hayden said. “Smoke and population health was a concern, and we found that 28 of New York’s 62 counties did not have a single air-quality sensor able to detect fine particulate matter... the main component of wildfire smoke.”

With support from a Cornell Atkinson Rapid Response Fund award, the research team was able to quickly purchase and install the new sensors.

Increasing Soil Organic Carbon and Crop Yields

A paper by Fellows Dominic Woolf and Johannes Lehmann (both Cornell CALS) shows that promised crop yield increases at a global scale would be negligible with current technologies and optimal management practices. They suggest that new strategies, such as redistributing carbon in the form of biochar, need to be evaluated.

Microplastics' Shape Determines How Far They Travel in the Atmosphere

Cornell researchers, including Fellows Qi Li and Natalie Mahowald (both Cornell Engineering), developed a model to simulate the atmospheric transport of microplastic fibers. They found that the fiber shape plays a crucial role in how far they travel. This modeling should help scientists determine the sources of microplastics, and inform policy efforts to reduce them.

Adding Crushed Rock to Farmland Pulls Carbon From Air

Adding crushed volcanic rock to cropland could play a key role in removing Carbon from the air. In a field study, Benjamin Z. Houlton (Dean, Cornell CALS), along with scientists at the University of California, Davis found that this type of rock weathering stored Carbon in the soil even during extreme drought.
