✦ Synopsis

Maximum entropy spectral analysis for the estimation of power spectra is used to study monthly and annual spectra of air temperature and precipitation at 63 weather stations in Duero Hydrographic Basin. Annual data are first submitted to the maximum entropy method (MEM) and the resulting power found are analysed. These spectra were then stratified according to the spectral peaks iind on this basis several climatic regions were defined for the Duero Basin. The MEM spectral estimates of monthly values clearly show the annual and semi-annual cycle.

Spectral analysis is an important method by which the variation in a data set can be decomposed into waves of different frequencies. In the form of the power spectral density it is usually estimated directly from the data using the fast Fourier transform which often requires considerable pre-process

The one-particle density in momentum space ␥ p is studied for diatomic molecules by using the maximum-entropy technique. The knowledge of one or more momentum ² n : Ž . expectation values p provides approximations on the density ␥ p for any value of the momentum, which are convergent when increasing

The objective of this study was to validate the soil moisture data derived from coarse-resolution active microwave data (50 km) from the ERS scatterometer. The retrieval technique is based on a change detection method coupled with a data-based modelling approach to account for seasonal vegetation dy
