[ES]En este estudio se presenta un nuevo algoritmo de detección de nubes aplicado sobre tierra a imágenes diurnas del sensor AVHRR (Advanced Very High Resolution Radiometer), a bordo de la serie de satélites de órbita polar NOAA. El algoritmo consta de cuatro tests espectrales que permiten clasificar cada píxel en cuatro categorías (nuboso, despejado, nieve-hielo y sin nieve-hielo), y se define para la detección de nubes durante el semestre cálido mayo-octubre en la Península Ibérica y las Islas Baleares. En este trabajo se presentan composiciones de frecuencia de la nubosidad convectiva con alta resolución espacial (1.1-km) para el año 2004, utilizando los pases de los satélites NOAA-17 (0900-1200 UTC) y NOAA-16 (1200-1500 UTC).
[EN]In this study a daytime over land multispectral cloud detection algorithm is presented with the aim to derive accurate daily cloud masks with high spatial resolution (1.1 km) over the Iberian Peninsula and the Balearic Islands. The cloud detection scheme is designed to process Advanced Very High Resolution Radiometer HRPT data and is tested here on NOAA-17 (0900-1200 UTC) and NOAA- 16 (1200-1500 UTC) overpasses for the warm 6-month study period May-October 2004. The algorithm consists of four spectral threshold tests applied to each pixel and the fixed or constant thresholds have been successfully tested to be functional during the central months of the warm season.
