Survey of observational data on desert dust storms and physical properties of dust (whit emphasis on results from complex observational programs accomplished in the USSR) has been given. Satellite observations of dust storms and their consequences have been considered in…

Some consideration of the adequate production of solar radiation information useful for solar energy planners and designers are shown here. Techniques for estimation of solar radiation on horizontal and inclined surfaces are discussed and  methods of application for developing countries…

Palaeomagnetic results for Mexico which cover the interval from the Cambro-Ordovician to Neogene are reviewed and briefly discussed in terms of regional tectonic models proposed for the evolution of Mexico. Following plate tectonic reconstructions of Atlantic bordering continents and the…

This work describes in detail a data acquisition and processing system for magnetotelluric data. The system is capable of doing real time data processing that is, at the time of acquisition and also uses the remote reference technique to get…

Se realiza un estudio estadístico de cuatro criterios para determinar el orden de un modelo autorregresivo (AR) a ser ajustado a datos de olas oceánicas. Los criterios son: a) mínimo del Error Final de la Predicción (PPE), b) mínimo de…

We interpret a new compilation of total-field magnetic anomaly data from the eastern part of the Maya Terrane, comprising aeromagnetic data for the Yucatán Peninsula and marine magnetic data for its northern and eastern continental margins. Qualitatively, on the basis…

Using data from a local seismic network operating in Chiapas, Southern Mexico, in 1979 plus two permanent stations VHO and COM, the geometry of the Benioff zone below 60 km depth was accurately mapped in the Tehuantepec area. The hypocenters…

Linear parametric models of sea surface temperature (SST) and air surface temperatures (AST) in the North Atlantic are considered. Theoretical aspects of the application of linear stationary Autoregressive Models (ARM) of observed scalar time series are discussed. Some results of…

Se estudia la propagación de señales de baja frecuencia en ocho años de datos (1982-1989) de Temperatura Superficial del Mar (TSM) en el noreste del Océano Pacífico. El análisis de las observaciones muestra que la variabilidad interanual de la TSM…

Métodos modernos de inversión en su forma estocástica se han aplicado a un conjunto de coeficientes de atenuación de las ondas de Rayleigh correspondientes a las placas Nazca-Cocos, para obtener modelos de fricción interna de las ondas de cizalla, Q-1β…
