The aspirated Stevenson screen with motor off produced low overall bias with lower maximum daily temperatures and higher minimum daily temperatures compared to the aspirated screen. Comparison
"The minima measured in the two exposures are similar throughout the year, with Stevenson screen minima being about 0.2C warmer. The maxima measured in the Stevenson screen are cooler than those in the Glaisher stand and the difference varies seasonally. The difference is only about 0.2C in winter, but reaches nearly 1C in summer." BOM Hiding The Heat Before 1910 Real Climate ScienceApr 06, 2017 · The results of this 61-year experiment show that summer daytime temperatures measured using the Glaisher Stand are, on average, 1C warmer than in the Stevenson Screen. You will find that, after the adjustments they make to the data (to ensure the early data can be reliably compared with modern data), some years in the 19th century were indeed warm.
Nov 12, 2009 · Ross, there are no temperature readings in the BoM database for Adelaide prior to 1887 as this is when the Stevenson Screen record starts in Adelaide. Any temperature readings prior to that are from a Glaisher stand, well known to read several degrees higher than the Stevenson Screen in hot conditions. It is important to compare apples with apples. Comment on Historical Thermometers Exposures in AustralliaNicholls et al give a brief account of the 1887-1948 experiment comparing temperatures measured in a Glaisher stand against those from a Stevenson screen and conclude that, "Over the year, the mean temperatures were about 0.2°C warmer in the Glaisher stand, relative to the Stevenson screen."
Stevensons screen, along with a special stand used at Kew, were the only screens employing louvres to ensure good ventilation and adequate screening from radiation in Gasters (1 882) comparison of screens in 1869.

The shelter details of only a few stations are currently available.
Apr 08, 2015 · 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
- Screening For QualityHot History?VerdictReviewMost people are familiar with the white Stevenson Screensyou can see at any weather-observing site around the country. But there is a great deal of documentary evidence indicating that, for much of the country, such screens were not widely used in Australia during the 19th century.

Nov 06, 2014 · The results of this 61-year experiment show that summer daytime temperatures measured using the Glaisher Stand are, on average, 1C warmer than in the Stevenson Screen. Historical Note:Greenwich, England Mean Temperature, 35 Feb 23, 2014 · A Stevenson Screen was in place at the observatory from about 1900, but the readings from it were not published and the Glaisher Stand was only replaced as the formal recording location in 1938. The comparisons of the screens found that, in summer, often the Stevenson Screen recorded maxima about 1F lower than in the Glaisher Stand, although on
Note that this "register" of a few meager lines of script covers a timespan of ~90 years and for a start there are no entries between 1859 and the 1890's. It is not clear if the entry Stevenson Screen (SS) July 1901 refers to a replacement or a new SS.

Oct 23, 2015 · The 555 is a replacement for the Stevens 512, which has a reputation for being a mule of a gun. The 555 is its prettier, slimmer cousin. What makes this shotgun stand out is the price. There is no other industry-smashing breakthrough here. But it did draw interest at the public range I took them to.
