Abstract: A new technique has been developed for the identification of inhomogeneities in Canadian temperature series. The objective is to identify two types of inhomogeneities?nonclimatic steps and trends?in the series of a candidate ...

Abstract: When a climatological station is relocated or is closing, it is often possible to join the climate observations of a nearby site to create a longer time series. However, joining climate observations can sometimes introduce ...

Abstract: On 1 July 1961, the climatological day was redefined to end at 0600 UTC (coordinated universal time) at all synoptic (airport) stations in Canada. Prior to that, the climatological day ended at 1200 UTC for maximum temperature ...

Abstract: Annual and seasonal trends in temperature, dewpoint, relative humidity, and specific humidity are presented for the period 1953?2005. The analysis uses hourly observations from 75 climatological stations across Canada. ...

Abstract: A method to homogenize daily maximum and minimum temperatures over Canada is presented. The procedure is based on previously defined monthly adjustments derived from step changes identified in annual Canadian temperature ...

Abstract: n 1 July 1961, the climatological day was redefined to end at 0600 UTC at all principal climate stations in Canada. Prior to that, the climatological day at principal stations ended at 1200 UTC for maximum temperature and ...
