A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined variation of the traditional H-index. The D-index exclusively accounts for publications and citations pertinent to the specific discipline under examination—in this case, Earth Science. This discipline-focused metric provides a more accurate reflection of a researcher’s impact within their specialized field.
Scope of Research Considered
The ranking assessment encompassed an extensive pool of 279,971 scientist profiles identified from an aggregation of bibliometric data sources spanning all academic disciplines. Within this dataset, a subset of 1,000 scientists specializing in Earth Science were carefully examined.
To qualify for inclusion in the ranking, a scientist was required to have a minimum D-index of 30, ensuring that only researchers with a significant body of impactful work were considered. Additionally, a majority of their tier publications had to be concentrated within Earth Science to affirm disciplinary relevance. Awards and notable achievements in the domain of Earth Science were also taken into account during the evaluation.
The D-index threshold for recognizing top researchers is dynamically set at increments of 10 relative to the estimated total number of scholars in each discipline, with a guiding principle to incorporate the top 1% of leading experts. This approach balances inclusivity with exclusivity, ensuring recognition of the highest-performing scientists. Furthermore, a proximity requirement was enforced such that the difference between a scientist’s general H-index and their D-index did not exceed 30%, emphasizing disciplinary focus alongside overall research excellence.
Verification and Validation Practices
The research team behind this ranking acknowledges that raw bibliometric data alone should never be considered an absolute measure of scholarly output or impact. To bolster the accuracy and integrity of the ranking, every scientist profile was meticulously manually verified and cross-correlated against publications and citation records found in an extensive array of trustworthy scholarly sources.
Although the number of papers published in leading journals and prominent conference proceedings does not directly influence a researcher’s ranking position, it serves as a valuable secondary indicator of their contributions to Earth Science. This supplementary verification lends further confidence in the quality and breadth of scholarly achievement recognized.
The final positions within the ranking are established through the D-index derived from data sources OpenAlex and CrossRef, reflecting the most current and authoritative bibliometric information available.
