Institutional rankings are determined by summing the D-indexes (Discipline H-index) of all scholars affiliated with each institution whose main publication focus is in Earth Science. The D-index is a discipline-specific metric, exclusively considering publications and citation data in the examined discipline, thereby providing a precise and reliable measure of scholarly impact within Earth Science.
Scope of Research and Selection Criteria
For the current edition, a comprehensive analysis was conducted on 279,971 scientist profiles identified from a wide range of bibliometric sources. Of these, 31,170 scientists specializing in Earth Science were subject to detailed analysis. To ensure excellence, only those scholars with a D-index threshold of at least 30 were considered, provided that the majority of their impactful publications are in the area of Earth Science. Additionally, recognition of scientists’ awards and notable achievements in the field of Earth Science played a role in the evaluation.
The D-index threshold for identifying top researchers adjusts in increments of 10, contingent on the number of scholars within each discipline, thereby guaranteeing the inclusion of the top 1% of leading experts. Another stringent criterion mandates that the gap between a scientist’s general H-index and their D-index remains within 30%. This ensures that rankings are discipline-focused. Awards and key professional accomplishments further influence the standing of scientists.
Verification and Data Validation Practices
Research.com is acutely aware that raw bibliometric data alone cannot wholly capture a scholar's contributions. As a result, every scientist’s profile included in the ranking has undergone manual verification and was carefully cross-referenced with publications in reputable, trustworthy sources. Although not a direct ranking factor, the volume of papers published in influential journals and at major conferences serves as a valuable secondary indicator of a researcher’s contribution to the field.
Positions in the ranking are established using each researcher’s H-index, sourced from OpenAlex and CrossRef, recognized as the world’s most reputable bibliometric databases within the research community.

Research.com’s Mission and Agenda
Our primary mission in creating this ranking is to inspire scientists, business leaders, and policymakers worldwide to follow emerging leaders within their discipline and to provide a comprehensive resource for identifying top experts in specific fields, across individual countries, or within their respective research institutions. We strive to facilitate greater visibility, foster collaboration, and highlight the centers of excellence driving Earth Science forward.
