The data obtained by a pyranometer equatorially mounted on a modified theodolite system were compared with those obtained by Temps and Coulson (1977) by a similar

Computations of the correlations with the most common used equations for long-wave radiation are performed. Brutsaert and Idso equations show the best fitting with experimental data. A new equation is proposed, with almost the same properties than Idso-Jackson's obtaining a better correlation coefficient.

Ates que no es tractava en aquest informe de generar nous resultats com a consequencia de nova activitat investigadora, la metodologia seguida ha estat, com en els capitols anteriors, la revisio bibliografica i documental d’articles i informes publicats fins avui. En concret, el principal document que s’ha utilitzat es l’informe titulat Generacion de escenarios regionalizados de cambio climatico para Espana (INM, 2007), que ha estat elaborat recentment per l'Institut Nacional de Meteorologia espanyol (actualment, Agencia Estatal de Meteorologia, AEMET). Les principals tecniques de regionalitzacio i els resultats mes destacats d’aquest document es resumiranen els propers apartats. Tambe hem emprat altres articles publicats en revistes cienti...
