A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a specialized metric that filters publications and citations exclusively within the Earth Science discipline. This strategic focus on discipline-specific data allows for a more precise assessment of a researcher’s influence and impact within their field, distinguishing it from broader general H-index measures.
Scope of Research and Selection Criteria
The ranking process began with the examination of 279,971 scientist profiles derived from diverse bibliometric databases spanning all academic disciplines. Within this extensive dataset, 1,130 scientist profiles classified specifically in Earth Science were analyzed. To qualify for inclusion in the ranking, candidates were required to meet a minimum D-index threshold of 30, ensuring that only researchers with significant scholarly impact were considered. Additionally, a majority of these scientists’ tier publications needed to be in Earth Science, underscoring their dedicated focus in this discipline.
Beyond citation metrics, scientists’ awards and notable achievements relevant to Earth Science were also evaluated as supplementary criteria. The D-index threshold is dynamically set in increments of 10 relative to the estimated total number of scholars within each discipline, thereby guaranteeing that at least the top 1% of leading experts are incorporated into the ranking. Furthermore, to maintain consistency and relevance, a scientist’s general H-index must not diverge from their D-index by more than 30%, preserving alignment between general scholarly impact and discipline-specific excellence.
Additional Verification and Validation Practices
Recognizing the limitations inherent in raw bibliometric data, the research team behind this ranking undertook meticulous manual verification of each scientist profile. This included cross-referencing publications and contributions with a broad spectrum of trustworthy sources to ensure the authenticity and accuracy of the data. Although not a direct criterion influencing the final ranking position, the quantity of papers published in prominent journals and leading conference proceedings is considered a valuable secondary indicator of a scientist’s active engagement and leadership within Earth Science research.
The final ranking positions are established based exclusively on the D-index metric, derived from information gathered from OpenAlex and CrossRef—two of the most prominent and widely utilized bibliometric databases available to the global research community. This methodological rigor strengthens the credibility and reliability of the ranking outcomes.
