A scientist's position within the ranking is determined by their D-index (Discipline H-index), a refined measure of scholarly impact that exclusively considers publications and citation metrics relevant to the examined discipline—in this case, Earth Science. This nuanced approach ensures that the evaluated scientific influence accurately reflects contributions within the specific field rather than overall academic output.
Scope of Research Considered
The ranking was constructed through an extensive examination of 279,971 scientist profiles aggregated from diverse bibliometric datasets across all academic disciplines. From this universe, the focus narrowed to the top Earth Science scholars identified across Colombia. Only those researchers with a D-index of at least 30, and whose majority of tier publications are centered in Earth Science, qualified for inclusion. Awards and notable achievements in the Earth Science domain also played an important role in the vetting process.
The threshold for the D-index is calibrated in increments of 10 relative to the estimated total number of scholars within each discipline, ensuring a robust representation of the top 1% of leading experts. Additionally, a strict criterion mandates that there be no more than a 30% difference between a scientist’s general H-index and their discipline-specific D-index, thereby confirming a strong alignment between overall impact and disciplinary focus.
Additional Verification Practices
Recognizing that raw bibliometric data cannot be the sole determinant of scholarly impact, the ranking process incorporates rigorous manual verification practices. Each scientist’s profile was carefully cross-verified against a broad spectrum of trustworthy publication sources to confirm accuracy and legitimacy. While not directly influencing rank placement, the number of publications in leading journals and prominent conference proceedings serves as a valuable secondary signal reflecting a researcher’s contribution to the Earth Science field.
The final ranking position derives from each researcher’s D-index, calculated using data from OpenAlex and CrossRef—widely acknowledged as the foremost bibliometric databases accessible to the global research community.
