A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only those publications and citation counts relevant to the specific field under examination—in this case, Earth Science. This focused approach ensures an accurate reflection of a researcher’s influence and productivity within their specialized domain, rather than across their entire portfolio of work.
Scope of Research Considered
The ranking process involved an initial analysis of 279,971 scientist profiles sourced from a diverse array of bibliometric databases, spanning all scientific disciplines. From this comprehensive pool, 20 scientists specializing in Earth Science within the Czech Republic were identified as candidates for inclusion.
To qualify for this ranking, a scientist must have a D-index of at least 30, with a majority of their tier publications concentrated in Earth Science. Additionally, notable awards and achievements related to the discipline were taken into account to further validate a researcher’s standing. The threshold for the D-index is set in increments of 10 and correlates with the estimated total number of scholars within each discipline—ensuring the top 1% of leading experts are consistently included in the ranking.
Moreover, the methodology requires that the gap between a scientist’s overall general H-index and their discipline-specific D-index be no greater than 30%, thereby confirming a strong alignment between their general research output and their impact within Earth Science.
Verification and Methodological Rigor
The Research.com team recognizes that raw bibliometric data alone cannot serve as an absolute measure of scholar output. Accordingly, all scientist profiles have undergone meticulous manual verification and cross-correlation against publications listed in an extensive range of trustworthy sources. This ensures the accuracy and reliability of the featured profiles beyond automated citation metrics.
While the number of papers published in prominent journals and conference proceedings does not directly affect the numerical ranking, such metrics are considered valuable secondary indicators of a researcher’s contribution to Earth Science and the broader scientific community.
The rankings are fundamentally established using each researcher's D-index derived from data obtained from OpenAlex and CrossRef, the foremost bibliometric databases accessible to the research community worldwide.
