Data Sources and Citation Metrics
The 5th edition of the Research.com Best Earth Science Scientists in Netherlands Ranking is primarily built upon bibliometric data aggregated from reputable sources such as OpenAlex and CrossRef, supplemented by multiple other trusted data sources. The citation-based metrics employed in devising this ranking were collected on January 12, 2026, ensuring the most up-to-date and accurate snapshot of scientific impact. A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a metric that exclusively accounts for papers and citation counts within the examined discipline of Earth Science, thereby providing a focused measure of domain-specific scholarly influence.
Scope of the Research
The compilation process involved an extensive examination of 279,971 scientist profiles identified across a broad spectrum of bibliometric databases covering all fields of study. Specifically, 136 scientists from the discipline of Earth Science in the Netherlands were analyzed in detail. To qualify for inclusion in the ranking, candidates were required to have a D-index of at least 30, with the majority of their tier publications firmly situated within the Earth Science domain. In addition to bibliometric performance, candidates’ awards and professional achievements within Earth Science were factored into their evaluation.
The D-index threshold for consideration among top researchers is calibrated in increments of 10, dependent on the estimated population size of scholars within each discipline. This approach ensures the inclusion of the top 1% of leading experts. Furthermore, eligibility demands a proximity of 30% or less between a scientist’s overall general H-index and their D-index, reinforcing the focus on discipline-specialized impact as opposed to general citation performance.
Verification and Quality Assurance
Recognizing that raw bibliometric data alone cannot serve as an absolute indicator of scholarly output or impact, the Research.com team implemented rigorous manual verification procedures. Each scientist’s profile was thoroughly reviewed and cross-correlated with publication records drawn from a diverse range of trustworthy sources. While the number of papers published in prominent journals and major conference proceedings does not directly influence ranking positions, it serves as a valuable secondary signal of a researcher’s substantive contributions to their field.
The position within the ranking hinges on each individual’s D-index, which is calculated based on data sourced exclusively from OpenAlex and CrossRef, two of the most prominent and respected bibliometric databases currently accessible to the research community.
