The 2nd edition of Research.com ranking of the best researchers in the
field of Earth Science relies os data
combined 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
scholar’s D-index (Discipline H-index), which
includes exclusively publications and citation
values for an examined discipline.
The focus of our Earth Science research
Our best scientists ranking is a credible list of leading researchers from the area of Earth Science, based on a detailed study of 166,880 researchers identified from various bibliometric data sources. For the area of Earth Science, more than 7637 researchers were investigated.
What is D-index inclusion threshold for Earth Science
The D-index threshold for including a researcher to be considered is established at 30 if most of their publications are in the area of Earth Science. The acceptance factors for scholars to be considered into the ranking of top scholars are based on the D-index, proportion of the publications made within the given area as well as the awards and achievements of the scientists. The D-index threshold for including best researchers is set as an increment of 10 depending on the overall number of scientists projected for each area od study whilst ensuring that the top 1% of leading researchers are incorporated into the list. There should be a proximity of 30% or less between a scientist’s general H-index and their D-index.
Additional verification rules
As our leading goal is to guarantee that only actual researchers are included in the ranking we realize that numbers are never supposed to be an absolute means to quantify the output of researchers. Because of that we manually inspect each profile and cross-correlate it against publications in a broad range of reliable sources. While it’s not a metric contributing to a researcher’s position in the ranking, the quantity of documents published in major journals and conference proceedings should be a credible secondary implication of their contribution to research in a given area of science. Position in the ranking is based on every researcher’s D-index using data gathered from OpenAlex and CrossRef, which are the most credible and well-known bibliometric databases of this kind available to the research community. A thorough definition of our research policy can be found on our methodology page.
Our mission is to motivate scholars, entrepreneurs and decision-makers around the world to explore where top experts are heading and to provide an opportunity for the whole research community to get to know who the leading experts in specific areas of study, in different countries, or even within research institutions are.
