Abstract
El presente trabajo realiza una prueba de concepto para una futura caracterización microclimática de una pequeña cuenca del macizo de Peñalara, un área situada en la Sierra de Guadarrama. Muestra las dificultades tecnológicas y conceptuales llegando a calcular unos resultados preliminares que muestran la variabilidad espacial y temporal de la región. La caracterización ha sido realizada mediante una red de medición fabricada con microcontroladores y sensores de bajo coste que han permitido la medición de la temperatura como variable meteorológica determinante. En el posterior análisis se ha hecho uso del método de interpolación geoestadístico kriging con deriva externa con la altitud como variable auxiliar, el cual ha permitido extrapolar a un dominio con una resolución de 2 metros. El método ha sido validado mediante una validación cruzada. Se ha concluido que la metodología seguida es válida para el estudio microclimático para futuras campañas de mayor alcance en las que debería contemplarse un estudio de medida más largo.
This study presents a proof of concept for a future microclimatic characterization of a small basin on Pe˜nalara’s massif, an area located in the Sierra de Guadarrama. It highlights the technological and conceptual challenges encountered, and provides preliminary results that reveal the spatial and temporal variability of the region. The characterization was carried out using a measurement network built with low-cost microcontrollers and sensors, which enabled the recording of temperature as a key meteorological variable. The subsequent analysis em ployed the geostatistical interpolation method kriging with external drift, using altitude as an auxiliary variable, which allowed extrapolation over a domain with 2-meter resolution. The method was validated through cross-validation. It was concluded that the methodology is suitable for microclimatic studies and can be applied in future, more extensive campaigns, where longer measurement periods should be considered.
