There is increasing evidence that the amount of solar radiation incident at the Earth's surface
is not stable over the years but undergoes significant decadal variations. Here I review the …

We use high quality climate data from ground meteorological stations in the Iberian
Peninsula (IP) and robust drought indices to confirm that drought severity has increased in …

The most recent debate on global warming focuses on the hiatus in global temperature, for
which several explanations have been proposed. On the other hand, spatial variability and …

In this study we analyzed the spatial distribution, temporal variability and trends in reference
evapotranspiration (ET 0) in Spain from 1961 to 2011. Twelve methods were analyzed to …

A new monthly precipitation database has been developed for conterminous provinces in
Spain by exploiting the total amount of data available at Spanish Meteorological Agency …

This paper presents trends in downward surface shortwave radiation (SSR) over Europe,
which are based on the 56 longest series available from the Global Energy Balance Archive …

Surface solar radiation has undergone decadal variations since the middle of the twentieth
century, producing global 'dimming'and 'brightening'effects,. These variations presumably …

This study analyzes changes in monthly reference evapotranspiration (ETo) by use of the
Penman‐Monteith equation and data from 46 meteorological stations in Spain from 1961 to …

It has been widely accepted that diurnal temperature range (DTR) decreased on a global
scale during the second half of the twentieth century. Here we show however, that the long …

This study analyzes the spatial and temporal changes in sunshine duration (SunDu) and
total cloud cover (TCC) over the Iberian Peninsula (IP) and four subregions during 1961 …
