The bibliometric data employed to devise the citation-based metrics for this ranking were meticulously collected on January 12, 2026. A key metric used to establish a scientist’s position in the ranking is the D-index (Discipline H-index), which measures the impact of an individual’s publication record exclusively within the examined discipline, ensuring a focused and discipline-specific evaluation of research influence.
Scope of Research and Selection Criteria
The ranking’s scope is defined by a comprehensive analysis of 279,971 scientist profiles drawn from a broad spectrum of bibliometric data sources, spanning all scientific disciplines. Within this extensive dataset, 5 scientists specializing in Earth Science in Ecuador were identified for inclusion in the ranking.
To qualify, a scientist’s D-index needed to meet a minimum threshold of 30, and the majority of their highest-tier publications were required to be in the field of Earth Science. Additionally, notable awards and achievements in Earth Science were considered in the evaluation process to further validate a researcher's standing within the discipline.
The threshold for the D-index is carefully calibrated as increments of 10, relative to the estimated total number of scholars in each discipline. This adaptive threshold ensures that the top 1% of leading researchers are represented in the ranking. Furthermore, a requirement that the proximity between a scientist’s overall H-index and their discipline-specific D-index remains within 30% guarantees alignment between their general and specialized research impact.
Verification and Validation Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the team behind this ranking conducted thorough manual verification of all scientist profiles. This involved cross-correlating each profile’s publication record against trusted sources to confirm accuracy and relevance.
While the number of papers published in eminent journals and prestigious conference proceedings does not directly affect ranking positions, it provides an important secondary signal regarding a scientist’s contribution to their field.
The position of each researcher is ultimately determined using their D-index, which is derived from data gathered through OpenAlex and CrossRef — the most prominent bibliometric databases accessible to the global research community.
