Sentences with phrase «not bias correction»

In particular, he explained the bias dependency on the lead time, also known as drift, and distinguished between two approaches for bias adjustment (and not bias correction): a non-parametric, consisting in adjusting each forecast time separately, and a parametric approach, where a function to adjust different forecast times at once is used.

For the calculated global warming it doesn't matter if you apply the correction to the ships or to the buoys, and the fact that ship intakes are warmer than the environment is irrelevant because of the bias correction and conversion to anomalies.

HadSST3 not only greatly expands the amount of raw data processed, it makes some important improvements in how the uncertainties are dealt with and has a more Bayesian probabilistic treatment of the necessary bias corrections.

Specifically, Watts did not apply a time of observation bias correction according to Howard Universitychemistry professor Josh Halpern, who blogs under the pseudonym Eli Rabett.

It clearly is a positive development to have your careful work acknowledged by the authors: however, although they did make a few corrections, they did not admit to what to me is to me the most important point — your paper's estimate was not biased low.

I am not competent to judge the correctness of the HadSST3 bias corrections: That is a discussion which will take place in the peer - reviewed literature over the next few years.

As a result, their «urbanization bias - corrected» global temperature trend estimates was pretty much the same as the estimates of the other groups who didn't apply any urbanization bias corrections (you can see this by looking back at Figure 1, at the start of the essay).

``... since uncertainty is a structural component of climate and hydrological systems, Anagnostopoulos et al. (2010) found that large uncertainties and poor skill were shown by GCM predictions without bias correction... it can not be addressed through increased model complexity....

If the TOBS error introduces enough uncertainty, then a trend may not be statistically significant, even if there is a bias correction.

Hence, if you do not correct for this bias, there will be a cool bias, relative to what would be the case where this correction applied.

The ICESat bias corrections used by the Zwally team were appropriate for measuring sea ice, but not for measuring high altitude land - base ice sheets like found in Antarctica (the values returned for Lake Vostok alone were so unphysical that they should have made the entire study DOA) 2.

But what is being done now is not dishonest (as Steve so often implies), but an honest attempt to create a bias correction.

The also say that: «When we do not adjust NMAT as discussed in section 2, our computed 1854 - 1941 bias correction is about constant».

This test does not prove anything except that you have made significant structural changes to the climate data in applying the bias correction (irrespective of whether it is a good or bad one).

The other quote «When we do not adjust NMAT as discussed in section 2, our computed 1854 - 1941 bias correction is about constant» is interesting and perhaps more interesting again in full:

And often corrections can not be made until many, many years later because you need lots of data before you can spot changes in bias.

If some corrections to the data are necessary, there is a need for systems to make these corrections in a way that does not introduce more bias than they remove.

It has been suggested that the absolute calibration of the m - cresol purple pH method may be slightly biased such that a +0.0047 correction to measured pH values is necessary (DelValls & Dickson 1998); we did NOT apply this correction factor to our pH measurements.»

However, as outlined by Bengtsson et al. (2004) and others (see IPCC AR4 Chapter by Trenberth), reanalysis datasets are not typically employed for climate change studies without considerable bias correction, and that is a difficult proposition in itself.

This circuit illustrates a much more accurate picture of reality in that it includes terms such as bias current, offset current, and offset voltage, and this equation is the corrected equation for the operation of the circuit (this equation is still missing two of the larger corrections, input and output resistance, because I didn't want to re-derive the equations — it gets really tedious really fast).

After the average field is constructed, it is possible to create a set of estimated bias corrections that suggest what the weather station might have reported had apparent biasing events not occurred.

The other members of the court (Simmons J.A. and Cronk J.A.) in separate concurring reasons, did not frame the proposition as broadly and cautioned that the jurisdiction to effect error correction will be precluded where it is tantamount to a reconsideration of the verdict or sentence or where issues of unfairness or injustice to the accused or reasonable apprehension of bias arise: (per Cronk J.A. at para. 60).

This method equalizes the backgrounds of Type I and Type II probes prior to normalization, and includes between - array normalization of Type I and Type II probes separately but does not perform dye bias correction.

Given the low number of fathers (n = 25) of 10 - years old girls responding via the Internet leading to increased risk for bias, presence of extreme values in the scores that violates the assumptions in the parametric analyses, and the fact that this finding would not remain after correction for multiple comparisons, all data were combined.
