Extending the Official Temperature Record Back in Time

·Three thermometer screens used in Adelaide,South Australia,in 1890 a Stevenson screen (left),a thermometer shed (centre),and a Glaisher stand (right).Charles Todd famously recorded the temperature in each of these screens for around 40 years,giving us invaluable information about the effect of different screens on temperature observations.FactCheck was the 1896 heatwave wiped from the record?·It was suggested that,when compared to the Glaisher stand,the Stevenson failed to record the maxima during cloudy weather,while in clear weather the air experienced heating up in the screen.37 It was also suggested,again compared to the Glaisher stand,that the lack of circulation in the Stevenson screen meant higher minimum temperatures.Folie 1 - meteo.uni-bonn.deSpain Montsouri screen,Stevenson observations,Stevenson automatic Montsouri vs.Stevenson difference as function of Diurnal Temperature Range and Tmax Murcia South East Spain,Mediterranean.La Corunia,Corunna North West Spain,Atlantic.Juli April Montsouri vs.Stevenson difference as function of Diurnal Temperature Range and Tmax
