Data Sources Utilized in the Ranking
The 5th edition of the Research.com Best Earth Science Scientists in Peru Ranking is grounded in comprehensive bibliometric data sourced primarily from OpenAlex and CrossRef, supplemented by multiple other reputable data repositories. These data sources provide extensive coverage of publication records, citation metrics, and author profiles across diverse scientific domains. The bibliometric information employed to calculate citation-based indicators for this ranking was meticulously collected on January 12, 2026. A scientist’s position within the ranking is determined based on the D-index (Discipline H-index), a metric that exclusively considers papers and citation statistics pertinent to the examined discipline, ensuring domain-specific evaluation of scholarly impact.
Scope of Research Examined
In developing the ranking, a total of 279,971 scientist profiles spanning all scientific disciplines were initially examined using bibliometric data aggregated from a variety of authoritative sources. From this comprehensive set, 2,403 scientists specializing in Earth Science were identified and evaluated in detail. To qualify for inclusion in the ranking, an individual scientist’s D-index was required to be at least 30, and a majority of their tier publications had to be within the Earth Science domain. Additionally, recognition of awards and notable achievements specifically within Earth Science contributed to the evaluation process.
The threshold for the D-index is calibrated in increments of 10 based on the estimated total number of scholars in each discipline, with an aim to consistently include the top 1% of leading researchers. To ensure disciplinary focus and relevance, a proximity criterion was applied whereby there must be no more than a 30% difference between a scientist’s overall H-index and their D-index, safeguarding the ranking’s emphasis on specialized research excellence.
Additional Verification Practices
The ranking team is acutely aware that raw bibliometric data alone cannot serve as an absolute arbiter of a scholar’s research output or contribution. Consequently, all scientist profiles were subjected to rigorous manual verification and cross-correlation against publications indexed in a broad spectrum of trustworthy sources. This thorough validation enhances the accuracy of the ranking by reducing errors associated with data aggregation and author disambiguation.
Although not a direct component influencing ranking positions, the quantity of papers published in prominent journals and leading conference proceedings is recognized as a valuable secondary indicator of a scientist’s substantive contributions to their field. Ultimately, researcher rankings are established based on the D-index calculated from authoritative data in OpenAlex and CrossRef, currently the most prominent and respected bibliometric databases accessible to the research community.
