The 2nd edition of Research.com ranking of the best researchers in the
field of Earth Science relies os data
consolidated from a wide range of 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 papers and citation
values for an examined discipline.
The scope of our Earth Science research
Research.com’s best scholars ranking is a reliable lineup of leading scholars from the area of Earth Science, established by means of a meticulous study of 166,880 scientists identified from multiple bibliometric data sources. For the area of Earth Science, over 7636 scholars were examined.
What is D-index approval threshold for Earth Science
The D-index threshold for approving a scholar to be examined is placed at 30 if the majority of of their publications are in the field of Earth Science. The acceptance factors for researchers to be considered into the ranking of top researchers are based on the D-index, ratio of the contributions made within the given discipline plus the awards and achievements of the researchers. The D-index threshold for listing best scholars is set as an increment of 10 depending on the total number of scholars estimated for each area od study whilst making sure that the top 1% of best scholars are considered into the list. We estimate a proximity of 30% or less between a scholar’s general H-index and their D-index.
Extra verification rules
Since our main goal is to make sure that only actual scientists are mentioned in the ranking we believe that metrics are never meant to be a complete means to assess the work of researchers. This is why we manually verify each profile and cross-correlate it against publications in a wide range of trustworthy sources. Even though it’s not a factor impacting a researcher’s position in our ranking, the quantity of papers published in prominent journals and conference proceedings should form a reliable secondary implication of their contribution to research in a given discipline. Position in the ranking is determined by every researcher’s D-index using metrics collected from OpenAlex and CrossRef, which are the most credible and well-established bibliometric databases of this kind available to the research community. A detailed definition of our research policy can be found on our methodology page.
Our aim is to inspire scholars, businessmen and decision-makers around the world to examine where top experts are heading and to provide a way for the whole research community to discover who the leading experts in specific fields of research, in different countries, or even within research institutions are.
