Sentences with phrase «temperatures over the instrumental period»

As LST closely tracks air temperatures over the instrumental period, we can also infer that air temperatures in this region of East Africa varied in concert with the global average and thus were controlled primarily by the major forcings influencing temperatures over this timescale, both natural (solar radiation, volcanism) and anthropogenic (greenhouse - gas emissions; refs 19, 20).

Wouldn't you want to plot the Tierney proxy temp against the entire record, plot the trend lines and see how they correlate to see if «LST closely tracks air temperatures over the instrumental period»?

Unfortunately, in their paper they neglected to show how the Lake Tanganyika LST «closely tracks air temperatures over the instrumental period» of the «past half - century».

So no, the LST proxy reconstruction does not «closely track air temperatures over the instrumental period.»

Not exact matches

Over the instrumental period, fractional uncertainty in the latter is very much larger than fractional uncertainty in temperature change measurements, and is approximately normally distributed.

Furthermore, temperature is a strongly trending series over the instrumental period.

That represents a triple offset to exagerate the predicted cooling as it incorporates the offset introduced by using UAH data instead of the simply using the NCDC data over the whole period, adds an additional offset by using the bottom of a La Nina event as a start year, and exagerates that La Nina event by using a satellite temperature record to show it while using instrumental record data for the predictions.

Instrumental temperature data are shown by a green line (centered to agree with CH - blend average over the period 1880 - 1960).

«The principal difficulty is that the divergence disallows the direct calibration of tree growth indices with instrumental temperature data over recent decades (the period of greatest warmth over the last 150 years), impeding the use of such data in climatic reconstructions.»

Temperature data over the past couple of decades is more telling than data from other time periods within the instrumental data set,

=== > That the different period cooling / warming trends exist in narrow to wider bands over the total instrumental temperature record

This time period is too short to signify a change in the warming trend, as climate trends are measured over periods of decades, not years.12, 29,30,31,32 Such decade - long slowdowns or even reversals in trend have occurred before in the global instrumental record (for example, 1900 - 1910 and 1940 - 1950; see Figure 2.2), including three decade - long periods since 1970, each followed by a sharp temperature rise.33 Nonetheless, satellite and ocean observations indicate that the Earth - atmosphere climate system has continued to gain heat energy.34

Over the instrumental period, fractional uncertainty in the latter is very much larger than fractional uncertainty in temperature change measurements, and is approximately normally distributed.

Several analyses of ring width and ring density chronologies, with otherwise well - established sensitivity to temperature, have shown that they do not emulate the general warming trend evident in instrumental temperature records over recent decades, although they do track the warming that occurred during the early part of the 20th century and they continue to maintain a good correlation with observed temperatures over the full instrumental period at the interannual time scale (Briffa et al., 2004; D'Arrigo, 2006).
