The 2nd edition of Research.com ranking of the best scientists in the
discipline of Earth Science relies os data
consolidated from multiple data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected on 21-12-2022. Position in the ranking is based on a
researcher’s D-index (Discipline H-index), which
includes exclusively papers and citation
values for an examined discipline.
The scope of our Earth Science research
Research.com’s best scholars ranking is a credible lineup of leading scholars from the area of Earth Science, established by means of a detailed analysis of 166,880 researchers discovered from multiple bibliometric data sources. For the discipline of Earth Science, as many as 7636 researchers were examined.
What is D-index acceptance threshold for Earth Science
The D-index threshold for approving a researcher to be considered is placed at 30 if the majority of of their publications are in the area of Earth Science. The acceptance factors for researchers to be considered into the ranking of top scholars are based on the D-index, proportion of the contributions made within the given field of study as well as the awards and achievements of the scientists. The D-index threshold for considering top researchers is set as an increment of 10 depending on the overall number of scientists projected for each discipline whilst ensuring that the top 1% of best scholars are added into the list. We expect a proximity of 30% or less between a researcher’s general H-index and their D-index.
Additional verification methods
As our leading goal is to ensure that only genuine scientists are mentioned in Research.com ranking we realize that metrics are never supposed to be an absolute measure to assess the work of scholars. This is why we manually inspect every profile and cross-correlate it against publications in a varied range of trustworthy sources. Although it’s not a factor impacting a researcher’s position in the ranking, the number of documents published in well-known journals and conference proceedings should constitute a credible secondary implication of their contribution to research in a specific field of study. Position in the ranking is established using each researcher’s D-index using information compiled from OpenAlex and CrossRef, which are the most credible and well-known bibliometric databases of this kind available to the research community. A thorough explanation of our research procedures can be found on our methodology page.
Our aim is to inspire scholars, businessmen and politicians worldwide to investigate where prominent experts are heading and to offer a way for the whole research community to get to know who the leading experts in specific fields of research, in various countries, or even within research institutions are.
