This
electronic thermometer is perfect
for all ages and especially
for parents with little children.
The surface temperature increase that partially gave rise to concerns about global warming coincided with a move to tethered
electronic measuring devices (um, I think that means
thermometers) that forced the movement of many stations closer to buildings and developed areas, causing warming that may not have been corrected
for.
Penrith may have recorded 47.3 C
for at least one - second this week, but Windsor is only 23 km north - east of Penrith, and on January 13th, 1939, it recorded 122F or 50.5 C with an old fashioned liquid
thermometer, not a modern noisy
electronic one.
Doug said: «Wouldn't it be possible to simply put an
electronic probe and a classic
thermometer into a Stevenson enclosure or a temperature controlled environment
for comparison?
In fact, Table 1 shows that
for the last month of available parallel measurements the
electronic probe (Tmax - Probe) often recorded considerably warmer than the mercury
thermometer (Tmax - LIG).
There are many more maximum temperatures measurements available
for the
electronic probe (n = 948) than
for the mercury
thermometer (n = 115), and the distribution is quite different, with a somewhat more normal distribution
for the probe data, as shown in Figure 2.
After I manually transcribed and analysed relevant data from a subset of the first batch of over 4,000 scanned A8 forms received on 28 October, I wrote to Minister Freydenberg on 12 November explaining that the values recorded manually on the A8 forms from the mercury
thermometers for the period November 1996 to December 2000 at Mildura are significantly different from the official values recorded from the
electronic probes.
Wouldn't it be possible to simply put an
electronic probe and a classic
thermometer into a Stevenson enclosure or a temperature controlled environment

Some are needed, but usually just as a one - off, as
for instance
for the switch to
electronic thermometers.
There is a study of a German transition from traditional glass mercury
thermometer measurement stations to the new
electronic measurement system, http://notrickszone.com/2015/01/14/germanys-warming-happens-to-coincide-with-late-20th-century-implementation-of-digital-measurement/, where a side - by - side run of the old and new equipment
for 8.5 years found that the new equipment yielded a temperature reading 0.93 C higher on average.
