Sentences with phrase «measurement uncertainty analysis»

A description of both the DESRAD concept and the Diurnal Test Facility is presented here along with examples of the model verification data and a brief measurement uncertainty analysis.

Not exact matches

Included are uncertainty analyses, maps of the measurement coverage and many illustrations of the regional and vertical distribution of the warming.

These measurements become sparser as we go further back in time, hence trend estimates become more uncertain; of course we fully accounted for this uncertainty in our analysis.

The two agencies use slightly different methods, so they have different readings for the difference between 2014 and the previous warmest year, 2010, with N.O.A.A. putting it at 0.07 degrees Fahrenheit (0.04 degrees Celsius), while NASA got 0.036 degrees (0.02 Celsius)-- which this analysis says is well «within uncertainty of measurement.»

Accounting for Both Random Errors and Systematic Errors in Uncertainty Propagation Analysis of Computer Models Involving Experimental Measurements with Monte Carlo Methods.

That is, (1) there is dO18 measurement, which I claim should be fairly precise, but you stated has large uncertainties, and then there is (2) derivation of temperature from dO18 values, where you have indeed pointed out that there could be a number of possibly confounding factors in that analysis if other variables than temperature are not controlled.

The use of even more recently computer - reconstructed total solar irradiance data (whatever have large uncertainties) for the period prior to 1976 would not change any of the conclusions in my paper, where quantitative analyses were emphasized on the influences of humans and the Sun on global surface temperature after 1970 when direct measurements became available.

He also presented evidence that much of the discrepancy was due to observational uncertainty, resulting from stratospheric cooling contaminating satellite measurements of tropospheric temperature (a point that's been noted by the NOAA satellite analysis team since at least 2004; see: «Contribution of stratospheric cooling to satellite - inferred tropospheric temperature trends»).

Heat moves around the ocean in mysterious ways, and as Trenberth notes there are considerable areas of uncertainty in deep water measurements, Arctic heat content and the analysis techniques themselves.

Yes, there is data analysis involved and there are uncertainties... but if you want to call them «guestimates» for this reason, you'd have to call basically every measurement in the universe a guestimate.

New analyses of balloon - borne and satellite measurements of lower - and mid-tropospheric temperature show warming rates that are similar to those of the surface temperature record and are consistent within their respective uncertainties, largely reconciling a discrepancy noted in the TAR.

Uncertainties should decrease closer to near - current dates (e.g. from denser and more accurate sampling)-- but note that these products also employ different QC and analysis methods, rely to varying degrees on satellite data, on sea - ice data to constrain polar SST, and on bias adjustments for historical changes in measurement methods.
