Sentences with phrase «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).

@ourchangingclimate: related to what TB brought up: How does the effective sensitivity (as derived from a straight summation over the instrumental period including OHU) differ from equilibrium sensitivity?
However, we were interested in how much influence unforced variability might have had on changes in the rate of warming over the instrumental period.
The red line is the 30 - year - average annual global temperature from the HadCRUT4 instrumental time series relative to 1961 — 1990, and scaled visually to match the standardized values over the instrumental period.
And, yes, Kyle Swanson and Anastasios Tsonis did note in their study that the recent cooling period appeared «unprecedented over the instrumental period.»
Where (equilibrium / effective) climate sensitivity (S) is the only parameter being estimated, and the estimation method works directly from the observed variables (e.g., by regression, as in Forster and Gregory, 2006, or mean estimation, as in Gregory et al, 2002) over the instrumental period, then the JP for S will be almost of the form 1 / S ^ 2.
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.
Over the instrumental period (since the 1850s), North Atlantic SSTs show a 65 to 75 year variation (0.4 °C range), with a warm phase during 1930 to 1960 and cool phases during 1905 to 1925 and 1970 to 1990 (Schlesinger and Ramankutty, 1994), and this feature has been termed the AMO (Kerr, 2000), as shown in Figure 3.33.
Matches to observations at the mid-Holocene and over the instrumental period are good.
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.
Where (equilibrium / effective) climate sensitivity (S) is the only parameter being estimated, and the estimation method works directly from the observed variables (e.g., by regression, as in Forster and Gregory, 2006, or mean estimation, as in Gregory et al, 2002) over the instrumental period, then the JP for S will be almost of the form 1 / S ^ 2.
