      In situ climatological observations are essential for studies related to climate trends and extreme events. However, in many regions of the globe, observational records are affected by a large number of data quality issues. ...
    • The influence of station density on climate data homogenization 

      Gubler, S.; Hunziker, Stefan; Begert, M.; Croci-Maspoli, M.; Konzelmann, Thomas; Brönnimann, Stefan; Schwierz, C.; Oria, Clara; Rosas, Gabriela

      (John Wiley and Sons Ltd, 2017-11)
      Relative homogenization methods assume that measurements of nearby stations experience similar climate signals and rely therefore on dense station networks with high-temporal correlations. In developing countries such as ...
