2014 Climate Research (CR)  
Three methodologies to guide the estimation of SR are discussed in this study, namely: Case 1: SR is measured, Case 2: SR is measured but sparse and Case 3: SR is not measured.  ...  In Case 3: the SR was first estimated at a regional scale for a longer time period using complete or sparse measured records of SR from which SR at the local scale was estimated.  ...  However, absence of a long-term (> 25 yr) satellite database is a limitation of this method. (3) Finally, empirical relationships and soft computing techniques (e.g.  ...
