Leaf phenology as one important driver of seasonal changes in isoprene emission...
Alves, Eliane Gomes; Tóta, Júlio; Turnipseed, Andrew A.; Guenther, Alex B.; Vega Bustillos, José Oscar W.; Santana, Raoni Aquino Silva deIsoprene fluxes vary seasonally with changes in environmental factors (e.g., solar radiation and temperature) and biological factors (e.g., leaf phenology). However, our understanding of the seasonal patterns of isoprene fluxes and the associated mechanistic controls is still limited, especially in Amazonian evergreen forests. In this paper, we aim to connect intensive, field-based measurements of canopy isopre...
CAPE and convective events in the southwest during the North American monsoon
Adams, David K.; Souza, Enio P.The relationship between atmospheric stability, measured as CAPE, and deep precipitating convection has been widely studied but is not definitive. In the maritime tropics, CAPE and precipitation are usually inversely correlated. In continental convection (i.e., midlatitude and tropical), no consistent relationship has been found. In this study of the semiarid Southwest, a moderate positive correlation exists, a...
GNSS precipitable water vapor from an Amazonian rain forest flux tower
Adams, David K.; Silva Fernandes, Rui Manuel da; Maia, Jair Max FurtunatoUnderstanding the complex interactions between water vapor fields and deep convection on the mesoscale requires observational networks with high spatial (kilometers) and temporal (minutes) resolution. In the equatorial tropics, where deep convection dominates the vertical distribution of the most important greenhouse substance-water-these mesoscale networks are nonexistent.
