Data Sources and Bibliometric Basis
The 5th edition of the Research.com Best Earth Science Scientists in Mexico Ranking is grounded in a robust and comprehensive dataset. The primary sources include OpenAlex and CrossRef, two of the most prominent and well-established bibliometric databases available to the global research community. These data were augmented by multiple other bibliometric sources to ensure breadth and accuracy. The bibliometric information used to devise citation-based metrics was collected on January 12, 2026. A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a focused metric that accounts solely for papers and citation data within the specific discipline under review—in this case, Earth Science.
Scope of Research and Qualification Criteria
The ranking evaluates scientific profiles collected from an extensive pool of 279,971 researchers identified across multiple bibliometric databases spanning all research disciplines. For the Earth Science category specifically, 24 scientists were examined in detail. To qualify for inclusion in this ranking, candidates were required to meet a minimum D-index threshold of 30. Additionally, the majority of their tier publications had to be firmly anchored in Earth Science. Consideration was also given to scientists’ awards and achievements within the field to support a holistic perspective on research excellence.
The D-index threshold is calibrated in increments of 10 based on the estimated total scholar population of each discipline, ensuring that the top 1% of leading experts are consistently represented. A key consistency check involves maintaining a maximum 30% proximity between a scientist’s overall H-index and their discipline-specific D-index, reinforcing focus on domain-relevant research impact.
Verification and Methodology Integrity
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly contribution, all scientist profiles underwent manual verification. Researchers behind the ranking meticulously cross-correlated profile data against publications documented in a wide array of trustworthy and authoritative sources. While not a factor influencing ranking position, the quantity of publications in prominent journals and conference proceedings is regarded as a valuable secondary signal of a scientist’s influence within the discipline.
The final ranking position is determined exclusively by each researcher’s D-index, calculated based on verified data extracted from OpenAlex, CrossRef, and complementary bibliometric platforms.
