Sentences with phrase «thermometer record»

He would then have seen that the problem was caused by the manner in which the land based thermometer record had been adjusted throughout the 1980s and 1990s.

While satellites clearly have some advantages over the surface thermometer record, such as better sampling, measuring temperature from a satellite is actually an incredibly difficult problem.

There was only one temperature swing of this size in the oldest thermometer record which dates back 350 years, and it was a down swing.

I suspect some readers who haven't thought about thermometer records much will find your results interesting.

While the satellite data record is shorter than the surface thermometer record, it has several strengths.

Actual thermometer records don't show the rise from the 1920s to the 1940s was quite that big and Marcott said for such recent time periods it is better to use actual thermometer readings than his proxies.

These include the primary surface temperature thermometer records (NASA GISS, NOAA, and HadCRUT); satellite measurements of the lower troposphere temperature processed by Remote Sensing Systems (RSS) and the University of Alabama - Huntsville (UAH); and 5 major reanalysis datasets which incorporate station data, aircraft data, satellite data, radiosonde data, buoy and ship measurements, and meteorological weather modeling.

The data is for central England and from 1680 it uses the 50 year average of the HadCET thermometer record.

All I got in return was a nasty reply — which only served to confirm my suspicion that Mann was hiding the data because they disagreed with the widely accepted thermometer record, which had suggested the existence of global warming.

Considering days when there is parallel data available in the temperature band of interest (the claimed - record hot day in September 2017 measured 37.7 degrees Celsius) the new probe has been found to measure up to 0.4 degrees hotter (e.g. 26 February 2013 the recording for the probe is 37.3, while the mercury thermometer recorded 36.9 on the A8 form).

In the absence of any thermometers during most of this period, the Hockeystick is based on an analysis of so - called proxy data, mostly tree rings, from before 1000 AD to 1980, where the proxy temperature suddenly stops and a rapidly rising thermometer record is joined on.

As someone in a comment in an earlier post pointed out, early thermometer records are probably not even accurate to fractions of a degree, so just how can anyone come up with this conclusion regarding heating or cooling?

Let us assume that the CET thermometer record is both adequate for its purposes of recoding temperature, accurate enough to be useable over along period of time, and that local conditions around this thermometer have not changed very much between the year 800 (600 BC?

Indeed, it can be argued that one of the problems with current climate science is that it contains too many meteorologists (who have access to thermometer records spanning a grand total of 150 years) and too few geologists (who view climate change through the prism of much longer time frames).

The clearest evidence for surface warming comes from widespread thermometer records.

I recall more than one guest lecture at our physics department's Centre for Global Change Studies displaying a graph of spectral analysis of temperature histories, with data from multiple time scale sources including thermometer records, ice core data, etc..

This thermometer record is imperfect, but researchers are working on improving it using new mathematical methods and experiments with some of the same centuries - old thermometers.

The first centuries of the thermometer record were intriguing but unreliable, and people like Callendar, Manley and Böhm approached them with the same caution as historians examining ancient manuscripts.
