:source = "Measurement and sampling uncertainties estimated using the approach of Brohan et al. (2006). Wherever Chan et al. (2024) data was available, the number of observations used corresponds to the ensemble mean of Chan et al. (2024), excluding observations that did not pass quality control checks according to the unhomogenized GHCNv4 data (Menne et al., 2018). Otherwise, the number of observations used corresponds to unhomogenized GHCNv4 data after quality control checks. For \"tier-1\" stations as defined by Chan et al. (2023), uncorrected sample variances by calendar month during the climatological period were calculated using the ensemble mean of Chan et al. (2024). For other stations, uncorrected sample variances by calendar month during the climatological period were calculated using homogenized GHCNv4 data." ;
