This paper describes the construction of a new data set of sunshine duration over the Iberian Peninsula (IP), based upon 72 monthly instrumental series covering the 1931 2004 period. Particular emphasis is placed upon the quality control, gap filling, and homogenization procedures. We also produced a gridded version of the homogenized data set covering the whole IP with 84 cells. We subsequently analyzed sunshine duration data in search of temporal variability, longterm trends, and spatial differences over the IP. The analyses were carried out on the mean series calculated for the whole IP and for four subregions, at annual, seasonal, and monthly resolution.

Abstract
This paper describes the construction of a new data set of sunshine duration over the Iberian Peninsula (IP), based upon 72 monthly instrumental series covering the 1931 2004 period. Particular emphasis is placed upon the quality control, gap filling, and homogenization procedures. We also produced a gridded version of the homogenized data set covering the whole IP with 84 cells. We subsequently analyzed sunshine duration data in search of temporal variability, longterm trends, and spatial differences over the IP. The analyses were carried out on the mean series calculated for the whole IP and for four subregions, at annual, seasonal, and monthly resolution.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
