| An important atmospheric goal of TOGA COARE is to determine the exchange of momentum, and sensible and latent heat in the western Pacific over the time scales of convective storms, westerly bursts and lower frequency events. TOGA COARE will also require detailed moisture budget studies in support of improved undestanding of sub-gridscale processes and the evaluation of model parameterization schemes systems do not provide observations on the temporal and spatial scales necessary to properly address these and other issues. We present the concept of the so-called Boundary-Layer Integrated Sounding System (BLISS) as a means to provide these measurements. The BLISS consists of a suite of demonstrated in situ and remote sensing subsystems which together provide... |

| Micrometeorological measurements, including direct eddy - correlation heat and moisture fluxes, have been made under light wind conditions in the western equatorial Pacific. The sea surface "cool skin" of about O.5°C was observed; air-sea temperature differences were 1-1.5°C larger than long term averages from merchant-ship data. Bulk transfer coefficients for both fluxes increased markedly as wind speed fell below 4 m/s, in excellent agreement with the predictions of Liu et al. (1979). Dissipation estimates of the fluxes are about half the covariance measurements below 4 m/s. Observations of the individual components of radiation suggest that commonly used empirical formulations overestimate both long - and short wave in this region by 15-20 W/m2.... |
