The 2nd edition of Research.com ranking of the best scholars in the
discipline of Earth Science is based on data
derived from multiple data sources including OpenAlex and
CrossRef. The bibliometric data for estimating the citation-based metrics were
gathered on 21-12-2022. Position in the ranking is based on a
researcher’s D-index (Discipline H-index), which
takes into account only publications and citation
data for an examined discipline.
The focus of our Earth Science research
Our best researchers ranking is a credible list of leading researchers from the field of Earth Science, based on a thorough examination of 166,880 scholars discovered from a variety of bibliometric data sources. For the area of Earth Science, more than 7637 scientists were analysed.
What is D-index inclusion threshold for Earth Science
The D-index threshold for including a researcher to be examined is established at 30 if the majority of of their publications are in the area of Earth Science. The approval factors for scientists to be considered into the ranking of top scholars are based on the D-index, proportion of the publications made within the given discipline in addition to the awards and achievements of the scholars. The D-index threshold for considering best scientists is set as an increment of 10 depending on the overall number of researchers assessed for each area od study whilst ensuring that the top 1% of best scientists are added into the ranking. We expect a proximity of 30% or less between a scholar’s general H-index and their D-index.
Additional verification rules
Since our leading goal is to guarantee that only genuine researchers are included in our ranking we believe that metrics are never meant to be a full tool to assess the output of researchers. For that reason we manually verify each profile and cross-correlate it against publications in a wide range of trustworthy sources. While it’s not a metric contributing to a scholar’s position in Research.com ranking, the amount of papers published in prominent journals and conference proceedings should be a valuable secondary signal of their contribution to research in a given discipline. Position in the ranking is established using every researcher’s D-index with the help of data compiled from OpenAlex and CrossRef, which are the most prominent and well-established bibliometric databases of this kind available to the research community. A detailed definition of our research procedures can be found on our methodology page.
Our aim is to motivate researchers, businessmen and decision-makers worldwide to examine where prominent experts are heading and to offer an opportunity for the whole scientific community to get to know who the leading experts in specific areas of study, in different countries, or even within research institutions are.
