Location of stations for which long-term precipitation (blue) and temperature (red) observations exist and for which the data have been homogenized (for temperature) and adjusted (for changes in the instruments for precipitation). Over the past two decades, monitoring technology has evolved and the climate observing network has transitioned from manual to automated observations. Procedures are currently under development for joining and adjusting past manual and current automated climate observations in order to preserve continuity for climate monitoring and trend analysis (Milewska et al. 2018; Vincent et al. 2018).
