The National Polar-orbiting Operational Environmental Satellite System's (NPOESS) Microwave Imager/Sounder (MIS) instrument is in development at the Naval Research Laboratory, with soil moisture sensing depth as one of the two Key Performance Parameters (KPPs). Based on the current design, the MIS sensor shares many channel configurations similar to the(More)
Stream water dissolved organic carbon (DOC) correlates positively with soil organic carbon (SOC) in many biomes. Does this relationship hold in a small geographic region when variations of temperature, precipitation and vegetation are driven by a significant altitudinal gradient? We examined the spatial connectivity between concentrations of DOC in(More)
With the advantages of high thermal efficiency and extra low NOx and soot emissions, homogeneous charge compression ignition (HCCI) combustion has become a promising combustion method. Comparing with the SI engine or diesel engine, it is hardly to control combustion phase and combustion period on a HCCI engine directly. Hence, sensing of combustion phase(More)
Ethanol is an attracted alternative fuel, while ethanol-gasoline blends can be a way for substituting some part of gasoline. To apply ethanol or ethanol-gasoline blends to DISI engines, the spray characteristics of various blends of the ethanol and gasoline (25%, 50%, 75% and 100% ethanol) as well as pure gasoline were investigated by means of high-speed(More)
Forest soils play a critical role in the sequestration of atmospheric CO2 and subsequent attenuation of global warming. The nature and properties of organic matter in soils have an influence on the sequestration of carbon. In this study, soils were collected from representative forestlands, including a subtropical evergreen broad-leaved forest (EBF), a(More)
