Soil types affect air quality predictions Texas A&M AgriLife Research graphic
The graphic shows the standard deviation of the four soil parameter values among the four soil layers. Blue indicates small standard deviations and maroon represents the largest. Soil parameter values represented include the slope of the soil moisture retention line (BEXP), soil moisture at air dry (SMCDRY), soil moisture at field capacity (SMCREF), and soil moisture at permanent wilting point (SMCWLT).

Incorporating soil data can improve air quality predictions, solutions

Scientists can use land surface models to simulate mass and energy fluxes between land surface and atmosphere, providing link between hydrological and atmospheric models used to predict air quality.

Solutions to challenges and policy questions that arise due to drought and increased air quality concerns might well be found by looking down — to the soil.
