In areas that have insufficient data coverage, significant assumptions are required to build a 3D geologic model.
Only sites that had complete data coverage over the three periods were included, thus 67 sites remained for the analysis [ 23].
The following section outlines key considerations pertaining to the design, implementation, and interpretation of local surveys that could ameliorate data coverage and compatibility problems, paving the way for increasingly integrated studies of AIV and other wildlife diseases.
Another reason for remarkable differences between model and observational results is that the data coverage in the IRI model is limited to certain geographical locations and there is scarceness of ionospheric data at other locations, especially in global equatorial zones.
Most tools are not transparent about data coverage (that is, what disciplines are included, what sources are indexed, or other such details about how data is gathered).
The propagation of back-projected energy is very similar to that expected from imperfect data coverage.
But the variation of the data averages is likely due to bins with rather sparse data coverage that are statistically not very reliable.
The service uses SMS, meaning it does not need mobile data coverage that is not as widely implemented in many places.
That was the outcome of the second study, in which a team from the California Institute of Technology made thorough use of the vastly improved data coverage that has been delivered by the Argo programme of remote, floating probes.
That is, with sufficient data coverage, the removal efficiencies in technical abatement options can be evaluated against chemical properties (physico-chemical) of selected chemicals, to allow the derivation of generalised results useful for emerging substances not yet identified.
