  Observations and Model Simulations of Carbon Monoxide Emission Factors from a California Highway

  摘要：

  A series of twelve intensively monitored 1-hr CO dispersion studies were conducted near Davis, CA, in winter 1996. The experimental equipment included twelve CO sampling ports at elevations up to 50 m, three sonic anemometers, a tethersonde station, aircraft measurements of wind and temperature profile aloft, and a variety of conventional meteorological equipment. The study was designed to explore the role of vehicular exhaust buoyancy during worst-case meteorological conditions, such as low winds oriented in near-parallel alignment with the road during a surface-based nocturnal inversion. From the study, field estimates of the CO emission factor (EF) from a California vehicle fleet were computed using two different methods. The analysis suggests that the CT-EMFAC/EMFAC (EMission FACtor) models currently used to conduct federal conformity modeling significantly overpredict CO emissions for high-speed, free-flowing traffic on California highways.

• Combined extraction of high spatial resolution wind speed and wind direction from SAR images: A new approach using wavelet transform
  作者：Nicolas Fichaux、Thierry Ranchin

  DOI：10.5589/m02-038

  日期：2002.1

  Low spatial resolution wind extraction from scatterometer data has reached an operational status and the results are widely used in global-scale meteorological models. A new need is emerging concerning high spatial resolution wind fields extraction for the offshore industry. This need can be managed using high spatial resolution data, such as those from synthetic aperture radar (SAR) sensors. This paper presents a combined wind parameters extraction algorithm at high spatial resolution from a single SAR image. This algorithm makes use of advanced signal-processing tools. The results are compared with in situ data and future prospects are presented.
