Abstract: Realistic dynamic systems are often strongly nonlinear, particularly those for the ocean and atmosphere. Applying variational data assimilation to these systems requires a tangent linearization of the nonlinear dynamics ...

Abstract: Reactive gas emissions (CO, NOx, VOC) have indirect radiative forcing effects through their influences on tropospheric ozone and on the lifetimes of methane and hydrogenated halocarbons. These effects are quantified here ...

Abstract: While structural damage detection based on flexural vibration shapes, such as mode shapes and steadystate response shapes under harmonic excitation, has been well developed, little attention is paid to that based on ...

Abstract: he design and operation of a Thin-Cloud Rotating Shadowband Radiometer (TCRSR) described here was used to measure the radiative intensity of the solar aureole and enable the simultaneous retrieval of cloud optical depth, ...

Abstract: Measurements of the spectra of fluctuations in wind velocity over the sea sensed by three basically different instruments are described. One comparison shows good agreement between spectra from a thrust anemometer and cup ...

Abstract: We present in this paper a study of the azimuthal anisotropy of the motion field observed during a six-day campaign in March 1986 using the MU radar in Shigaraki, Japan. The radial wind velocity was observed at 20° zenith ...

Abstract: Accurate measurement of fluctuations in temperature and humidity are needed for determination of the surface evaporation rate and the air-sea sensible heat flux using either the eddy correlation or inertial dissipation ...

Abstract: High-resolution surface fluxes over the global ocean are needed to evaluate coupled atmosphere?ocean models and weather forecasting models, provide surface forcing for ocean models, understand the regional and temporal ...
