The 2nd edition of Research.com ranking of the best scientists in the
discipline of Earth Science relies os data
combined from a wide range of data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
acquired on 21-12-2022. Position in the ranking is based on a
scientist's D-index (Discipline H-index), which
includes exclusively publications and citation
metrics for an examined discipline.
The focus of our Earth Science research
Research.com’s best scientists ranking is a reliable list of leading scientists from the field of Earth Science, established by means of a meticulous examination of 166,880 scientists discovered from various bibliometric data sources. For the area of Earth Science, more than 7637 scientists were examined.
What is D-index acceptance threshold for Earth Science
The D-index threshold for accepting a researcher to be evaluated is established 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 researchers are based on the D-index, ratio of the contributions made within the given area in addition to the awards and achievements of the scholars. The D-index threshold for considering leading scientists is set as an increment of 10 depending on the overall number of scholars estimated for each area od study whilst guaranteeing that the top 1% of best scholars are considered into the ranking. We estimate a proximity of 30% or less between a scholar’s general H-index and their D-index.
Additional verification methods
Because our primary goal is to make sure that only credible scientists are mentioned in our ranking we realize that numbers are never meant to be a full tool to evaluate the work of researchers. This is why we manually verify every profile and cross-correlate it against publications in a varied range of credible sources. Even though it’s not a element impacting a researcher’s position in the ranking, the number of documents published in major journals and conference proceedings should constitute a valuable secondary signal of their contribution to research in a given discipline. Position in the ranking is based on each scholar’s D-index with the help of metrics collected from OpenAlex and CrossRef, which are the most trustworthy and well-known bibliometric databases of this kind accessible to the scientific community. A thorough definition of our research policy can be found on our methodology page.
Our goal is to inspire researchers, companies and politicians around the world to examine where top experts are heading and to provide an opportunity for the entire research community to get to know who the leading experts in specific disciplines, in different countries, or even within research institutions are.
