Sentences with word «inhomogeneity»

A significant source of inhomogeneity in spatial averages computed from these analyses arises from spurious changes in the climatology as the mean location of the network changes over time.

If I have understand it correctly, the fact that the NOAA approach to TOBS correction (based on metadata) and the BEST approach (which ignores the metadata and just looks for inhomogeneities in the data) give similar results is extremely compelling.

We suggest in an upcoming paper that the temperature in 1940 - 45 is exaggerated because of data inhomogeneity in WW II.

This is done by NOAA and is due to better algorithm for detecting inhomogeneities in temperature record (see here).

However, scientists must eliminate any artificial inhomogeneities caused by a growing population that alters the surface and adds waste heat, or when stations relocate to a different micro-climate.

The third is sampling error due to atmospheric horizontal inhomogeneity of the field of view (FOV).»

NCDC uses two correction processes to remove inhomogeneities associated with factors unrelated to climate such as changes in observer practices, instrumentation, and changes in station location and environment that have occurred through time.

Allowing for such inhomogeneities is an interesting and not very easy statistical problem.

Room - temperature investigations apply several techniques (polarization microscopy, single - molecule imaging, emission time dependence, energy transfer, lifetime studies, and the like) to a growing array of biophysical problems where new insight may be gained from direct observations of hidden static and dynamic inhomogeneity.

The big problem with much of the discussions about trends in hurricane activity is that the databases that everyone is working from are known to have significant inhomogeneities due to changes in observing practice and technology over the years.

Because of inhomogeneities within the station records and the inadequate and time - varying spatial sampling it is inevitable that multiple, somewhat distinct, estimates will result from running different algorithms on the recommended merge version of the databank.

Category 4 - 5 hurricanes show a pronounced increase since the mid-1940s (Bender et al., 2010) but again, we consider that these data need to be carefully assessed for data inhomogeneity problems before such trends can be accepted as reliable.

Our nickel oxide anode only transforms into metallic nickel through nanoscale inhomogeneities or defects in the surface structure, a bit like chinks in the anode's armor.»

«Initially, our research was driven by our desire to study how inhomogeneities in the structure of polycrystalline photovoltaics could affect the conversion of sunlight to electricity and how these devices can be improved,» says Heayoung Yoon, the lead author of the paper.

The findings are believed to be very general, but the investigation should clearly be extended also to other model systems to further support the view of coinciding structural and dynamical inhomogeneities being responsible for glass formation.

Using the EDS spectrometer, the team identified chemical inhomogeneity and its correlation with the phase changes that occurred in the material.

Note that studies using radiosonde data may be affected by recently discovered inhomogeneities (Section 3.4.1.1), although Forest et al. (2006) illustrate that the impact of the radiosonde atmospheric temperature data on their climate sensitivity estimate is smaller than that of surface and ocean warming data.

In 1982 Andrei Linde proposed a working model of inflation in which the universe would gracefully exit from the exponential expansion phase without producing unacceptable inhomogeneities.

However, Guth's simple and elegant model was flawed: as he himself recognized, it would lead to gross inhomogeneities in the distribution of matter on large scales.
