Managing wind erosion is an urgent challenge for maintaining productive agroecosystems, mitigating human risk, and maintaining ecosystem services under a changing climate. Wind erosion selectively removes fine soil particles, nutrients and carbon, which degrades air quality, reduces soil productivity and decreases ecosystem resilience to climate stressors. Wind erosion simultaneously impacts carbon stocks and carbon cycling, influences the efficacy of climate change mitigation, and reduces the potential benefits of adaptation strategies. The ability to conveniently access information on soil erosion rates and interpret likely responses to management is critical for land managers to make informed selections of conservation practices. The National Wind Erosion Research Network (NWERN), established in 2014 as a multi-partner effort with the USDA Long-Term Agroecosystem Research (LTAR) network, supports new research into wind erosion across agroecosystems and the development of new tools and information to support management. The NWERN uses standardized protocols for data collection to address long-standing data quality and interoperability challenges in aeolian research. We present an overview of the NWERN and an update on the development of an Aeolian Erosion (AERO) model using standardized network data. We then describe how AERO is applied to large standardized vegetation monitoring datasets collected by land management agencies across the western US, and findings of new research leveraging the monitoring datasets and model to assess impacts of ecosystem disturbances on sediment transport and dust emissions.
