\section{Material \& Methods}  Multivariate regression is employed to characterize the influence of ENSO and Volcanoes volcanoes  on temperature. EOF analysis of fitted values of multivariate regression generates fitted EOFs and Principal Components (PCs). Spatial sparsity is dealt by Ordinary Kriging (OK) and 100 gap-filled ensemble members are constructed to account for uncertainty.\\ A few words the general approach adopted. \citet{Neuro2013} might want to know about text text text text Text Text Text Text Text Text Text Text Text Text Text Text. \citet{Gene2012} might want to know about text text text text  Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text. \cite{Neurobot2013} might want to know about text text text text
