[1] We examine the ozone production efficiency in transpacific Asian pollution plumes, and the implications for ozone air quality in California, by using aircraft and surface observations in April–May 2002 from the Intercontinental Transport and Chemical Transformation 2002 (ITCT 2K2) campaign off the California coast and the Pacific Exploration of Asian(More)
Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Total atmospheric OH reactivities (k OH) have been measured as reciprocal OH lifetimes by a newly developed instrument at a rural(More)
We studied the effects of applying 50 kg(N) ha−1 year−1 of nitrogen (N) on needle photosynthesis, N allocation and nutrient content in the sun- and shade crowns of the hybrid larch F1 (Larix gmelinii var. japonica × L. kaempferi). The light-saturated net photosynthetic rate (P Nmax) was not significantly affected by N application or crown position, although(More)
Nanostructured Al–Fe alloys produced by e-beam deposition: static and dynamic tensile properties Abstract Three different aluminum–iron alloys were produced by electron-beam deposition with the iron content in the range 1.15–1.71 at.%. These alloys did not contain any identifiable iron-bearing particles, and exhibited full density with high-angle grain(More)
The Pacific Exploration of Asian Continental Emission Phase A (PEACE-A) aircraft measurement campaign was conducted over the western Pacific in January 2002. Correlations of carbon monoxide (CO) with carbon dioxide (CO 2) and back trajectories are used to identify plumes strongly affected by Asian continental emissions. ∆CO/∆CO 2 ratios (i.e., linear(More)
The permittivities and the resistance to moisture of LaYOx (LYO) films annealed at 600degC with different Y concentrations are investigated. The permittivities of 40%Y-LYO film and 70%Y-LYO film are higher than 25. The high permittivities come from the well crystallized hexagonal phase of LYO films. For rare earth oxides, the hexagonal phase shows higher(More)
