Data Sources and Citation Metrics
The 5th edition of the Research.com Best Earth Science Scientists in Austria Ranking is based primarily on bibliometric data sourced from OpenAlex and CrossRef, supplemented by multiple other reputable data repositories. To ensure the most current and comprehensive citation-based metrics, all relevant data were collected on January 12, 2026. The fundamental metric governing the ranking is the D-index (Discipline H-index), a specialized adaptation of the traditional H-index that exclusively includes papers and citations directly associated with the Earth's Science discipline under examination. This approach ensures that each scientist's position reflects their specific impact and scholarly contributions within the targeted field.
Scope of Research and Ranking Criteria
The ranking process commenced with the examination of 279,971 scientific profiles curated from a broad array of bibliometric data sources encompassing all scholarly disciplines. From this expansive pool, 50 scientists specializing in Earth Science were identified for detailed assessment. To qualify for inclusion, a scientist’s D-index needed to be at least 30, complemented by a publication record where the majority of tier publications aligned with Earth Science research. Additionally, consideration was given to notable awards and achievements within this discipline.
The threshold for D-index varies based on the estimated total number of scholars per discipline and is incremented by 10-point intervals to ensure the inclusion of the top 1% of researchers within each field. Furthermore, a proximity criterion is enforced to safeguard the relevance of the D-index: the gap between a scientist’s general H-index and their D-index must not exceed 30%, thereby ensuring that their discipline-specific impact closely mirrors their overall scientific influence.
Verification and Quality Assurance Procedures
The Research.com team recognizes that raw bibliometric data alone cannot fully capture the nuanced output and influence of scholars. Consequently, all scientist profiles underwent manual verification, wherein data were cross-validated against publications listed in a wide range of trustworthy and authoritative sources beyond OpenAlex and CrossRef. While the ranking itself does not directly account for the number of papers published in leading journals and conference proceedings, this secondary metric serves as an additional indicator of a scholar's contribution and standing within the Earth Science community.
To reiterate, the ranking positions are derived strictly from each researcher’s D-index, calculated with bibliometric information consolidated from OpenAlex and CrossRef — two of the most prominent and widely respected databases accessible to the global research community.
