Wind changes the surface of the Earth, but the surface characteristics of the planet also impact the winds above it. Here, the authors propose a feedback process in which wind erosion in the western Gobi Desert alters the thermal properties of the su

Many low-cost particle sensors are available for routine air quality monitoring of PM2.5, but there are concerns about the accuracy and precision of the reported data, particularly in humid conditions. The objectives of this study are to evaluate the

The accurate characterization of near-surface winds is critical to our understanding of past and modern climate. Dust lofted by these winds has the potential to modify surface and atmospheric conditions as well as ocean biogeochemistry. Stony deserts

Recent advancement in lower-cost air monitoring technology has resulted in an increased interest in community-based air quality studies. However, non-reference monitoring (NRM
e.g., low-cost sensors) is imperfect and approaches that improve data
