A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined metric that solely incorporates publications and citation counts pertinent to the examined discipline—in this case, Earth Science. This approach ensures that the evaluation reflects disciplinary excellence rather than overall research output.
Scope of Research and Ranking Criteria
The ranking encompasses an extensive review of 279,971 scientist profiles identified from a variety of bibliometric data sources spanning all disciplines. From this global pool, 1,234 scientists specializing in Earth Science were examined in detail for relevance and impact within this specific field.
To qualify for inclusion in the Earth Science ranking, a researcher must demonstrate a D-index of at least 30, with a majority of their tier publications firmly anchored in Earth Science topics. Additionally, awards and notable achievements within the field have been factored as qualitative measures of scholarly influence and recognition.
The D-index threshold is strategically calibrated in increments of 10, reflecting the total estimated number of scholars per discipline. This dynamic threshold setting guarantees that the top 1% of leading researchers are effectively incorporated into the list. Moreover, to ensure a focused disciplinary impact, a proximity criterion is applied wherein the difference between a scientist’s general H-index and their Earth Science D-index does not exceed 30%.
Verification and Quality Assurance
Recognizing that raw bibliometric data alone cannot fully encapsulate a researcher’s contributions, the team behind this ranking has implemented a rigorous manual verification process. Each scientist profile was carefully cross-checked against publications indexed in a broad spectrum of reliable and trustworthy sources, ensuring accuracy and consistency throughout the dataset.
While the number of papers published in prominent journals and conference proceedings is not directly used to determine ranking positions, it serves as a valuable secondary indicator of a scientist’s impact in their specific area of Earth Science research. The core ranking metric—the D-index—is established strictly according to information sourced from OpenAlex and CrossRef, which remain the most prominent and widely respected bibliometric databases available to the research community today.
