  • Climatic change ; Climatic data ; Climatology ; Fitting ; Multidimensional scaling ; Precipitation ; Statistical bias ; Temperature
  • The majority of documented climatic data set biases can be divided into two categories : physical biases and calendar biases. Previous homogenization efforts for prominent temperature and precipitation data sets are detailed in this review. Numerous
