Data Sources and Citation Metrics
The 5th edition of the Research.com Best Earth Science Scientists in Chile Ranking is primarily based on bibliometric data aggregated from OpenAlex and CrossRef, alongside multiple other trusted data sources. The citation-based metrics used to establish the ranking were meticulously collected on 2026-01-12, ensuring the dataset reflects the most current scholarly impact and publication record. A scientist’s position within this ranking is determined by their D-index (Discipline H-index), a refined metric that considers publications and citation counts exclusively within the examined discipline of Earth Science. This targeted approach enables a more precise evaluation of subject-specific research contributions rather than general academic influence.
Scope of Research and Qualification Criteria
The ranking process involved a comprehensive examination of 279,971 scientist profiles compiled from diverse bibliometric databases across all fields of research. Within the discipline of Earth Science, a focused analysis was conducted on 22 scholars identified as leading contributors. To qualify for inclusion in this ranking, a scientist’s D-index had to meet or exceed the threshold of 30, ensuring a high level of disciplinary impact. Additionally, the majority of their tier publications had to be within the Earth Science domain. Consideration was also given to their awards and notable achievements in this field.
The D-index threshold is dynamically calibrated—in increments of 10—based on the estimated total number of active scholars in the discipline. This approach guarantees the inclusion of the top 1% of leading experts in the area. Furthermore, a proximity criterion is applied whereby the disparity between a scientist’s general H-index and their D-index must be 30% or less, thus confirming the scholar’s consistent research excellence both broadly and within Earth Science.
Verification Practices and Ranking Methodology
The research team behind this ranking fully acknowledges the inherent limitations of relying solely on raw bibliometric data to assess scholarly output. Consequently, all scientist profiles were subject to additional manual verification and cross-correlation against publications from a broad spectrum of reputable sources. While the number of papers published in prestigious journals and high-impact conference proceedings is not directly factored into the ranking position, this measure serves as a valuable secondary indicator of a researcher’s contribution to their scientific community.
The ranking itself is finalized using each individual researcher’s D-index, derived from reliable information gathered from OpenAlex and CrossRef—two of the most prominent and well-established bibliometric databases accessible to the global research community.
