Título: Estimation of anisotropic temperature perturbation statistics of MREA'03 data'', Acoustic - Oceanographic Buoy - AOB

Resumo: In order to oceanographically map a given area, deterministic models of oceanographic processes have been coupled with statistical interpolation tools, to overcome the sparsity of oceanographic measurements. These tools assume some prescribed model for the inter-correlation between physical quantities. One characteristic model –a modified Gaussin with space-time dependence–, is here fitted to temperature data correlations from the MREA ’03 sea trial. The model is parameterized by four correlation lengths and a scaling factor. The model was fitted to two differently originated data correlations: one, from data measured by a spatially fixed single instrument or by CTD casts in the area; the other, from stacked data measured by all temperature monitoring instruments. The results show that the actual temperature perturbation field is not homogeneous, nor stationary, what was expected. The determination of the horizontal correlation lags was possible only via the combination of multiple-instrument data.
