Airborne observations of methane emissions from rice cultivation in the Sacramento Valley of California
[1] Airborne measurements of methane (CH4) and carbon dioxide (CO2) were taken over the rice growing region of California’s Sacramento Valley in the late spring of 2010 and 2011. From these and ancillary measurements, we show that CH4 mixing ratios were higher in the planetary boundary layer above the Sacramento Valley during the rice growing season than they were before it, which we attribute ...
متن کاملEffects of Wildfire on Blue Oak in the Northern Sacramento Valley
The objective of this project was to develop a technique for rapidly determining the extent of wildfire damage to blue oaks (Quercus douglasii) that would be usable by landowners without requiring extensive training. In late winter 2000, 100 oaks of various sizes and degrees of damage were selected from 10 plots located where wildfires had burned in the previous year. Measures of individual tre...
متن کاملUse of micro-XANES to speciate chromium in airborne fine particles in the Sacramento Valley.
While particulate matter (PM) in the atmosphere can lead to a wide array of negative health effects, the cause of toxicity is largely unknown. One aspect of PM that likely affects health is the chemical composition, in particular the transition metals within the particles. Chromium is one transition metal of interest due to its two major oxidation states, with Cr(III) being much less toxic comp...
متن کاملDevelopment of the Lower Sacramento Valley Flood-Control System: Historical Perspective
Natural physical conditions and the politics of flood management provide the historical context for structural flood control that underlies modern flood hazards in the Sacramento Valley. The valley is a broad, low plain with backswamp basins that were frequently inundated prior to Anglo-American settlement, continuing until the modern flood-control system was established. Early attempts to emul...
متن کاملHydrology of Vernal Pools on Non-Volcanic Soils in the Sacramento Valley
The hydrology of vernal pools near Mather Air Force Base in Sacramento County was investigated to assess the relative importance of direct precipitation, overland flow, and subsurface flow on the water level regime of vernal pools located on a Redding-Red Bluff soil complex, and to determine if constructed pools affected the hydrology of naturallyoccurring pools. Studies included direct continu...
