ABSTRACT:Complete monthly series of precipitation data have been generated for 932 stations run by the Instituto Nacional de Meteorología (INM) in Andalusia (Andalucía, southern region of Spain) and some adjacent areas for the period 1961-2000 using a new method for the estimation of missing data. The proposed method fills in the gaps in the climatological series for a target station using precipitation data from neighbouring stations with a similar precipitation pattern. Particular emphasis is made in the consideration of the precipitation data uncertainty. A set of possible estimates for the missing data are obtained assuming a linear relationship between the target station and the selected neighbour stations. The final imputed value is the median of the previously evaluated estimates distribution. This approach also provides the uncertainty of the missing data estimate. As an application, the suggested approach is used to obtain a precipitation map of Andalusia, as well as the average annual series for the examined period.

Resumen: En este artículo se estima el comportamiento futuro del nivel medio del mar en las Islas Canarias a partir de registros locales procedentes de mareógrafos y satélites altimétricos (con información sobre el comportamiento reciente del nivel del mar en la superficie marina). La metodología empleada consiste en realizar un análisis de regresión lineal entre dichos registros locales recientes y una serie global correspondiente al mismo periodo temporal, identificando en cada una de las rectas de regresión lineal correspondiente los valores referidos a tres escenarios futuros del IPCC, que indican las expectativas locales de cambio del nivel del mar tanto en los mareógrafos como en la superficie marina. Los resultados obtenidos muestran que se producirán subidas generalizadas del nivel medio del mar en todo el área de estudio. En dos de los mareógra-fos analizados y en la mayor parte de las aguas canarias se producirán subidas por encima de las expectativas del IPCC, mientras que en el tercer mareógrafo, en Lanzarote, los resultados indican ascensos del nivel del mar inferiores a las predicciones globales para el final del siglo XXI.Palabras clave: subida del nivel del mar, mareógrafo, altimetría por satélite, regresión lineal, Islas Canarias.

Territorial cohesion has become one of the policy objectives more clearly shared by the member states of the European Union in the last decade. At the same time, progress has been made in its definition from various initiatives, including the consultation conducted by the Commission through the Green Paper on Territorial Cohesion in 2008. Despite this progress, it is still considered a fuzzy concept on the need for further specifying in order to make it operational for the purposes of public policy design. This article makes a proposal for its definition and measurement at a regional scale, from the experience accumulated after the Territorial Development Reports of Andalusia.
