Understanding ice nucleating particles associated with agricultural soils
EMSL Project ID
50466
Abstract
The atmospheric concentration of ice-nucleating particles (INPs) impacts the formation and development of cloud ice crystals, affecting cloud radiative properties and precipitation. However, predictive understanding of INP concentrations in the atmosphere is limited in part by gaps in understanding the sources of particles that act as INPs. In particular, laboratory and field measurements suggest that agricultural soils rich in organic matter are more efficient INPs than organic-poor mineral dusts from deserts, but the physicochemical properties that control this behavior are not well-understood.The goal of this project is to improve understanding of the physical and molecular-level chemical characteristics of agricultural soil particles that control their ability to act as atmospheric ice nucleating particles (INP). We will do this by taking advantage of the unique capabilities and tool suite EMSL offers to characterize the agricultural soil particles that are capable of acting as INPs at different temperatures.
Results from this project will ultimately be used to improve predictive understanding of INP concentrations in regions impacted by agricultural emissions.
