Scope of Research and Selection Criteria
The ranking process began with an examination of 279,971 scientist profiles identified across a wide range of bibliometric data sources, covering all academic disciplines. Within this extensive dataset, 4 scientists specializing in Earth Science and affiliated with Estonia were evaluated in detail.
To qualify for inclusion in the ranking, candidates were required to have a D-index of at least 30, reflecting a robust level of scholarly output within Earth Science. Additionally, a majority of tier publications for each scientist had to be directly relevant to Earth Science. Other factors such as awards and recognized achievements within the Earth Science community were also considered to ensure comprehensive evaluation.
The D-index threshold for identifying top researchers is calibrated in increments of 10 based on the estimated total number of scholars in each discipline. This approach guarantees the inclusion of approximately the top 1% of leading scholars. Furthermore, to maintain consistency and disciplinary focus, candidates were required to have a proximity of 30% or less between their overall H-index and their discipline-specific D-index.
Verification and Quality Assurance Practices
At Research.com, we understand that raw bibliometric data alone cannot provide an absolute evaluation of a researcher’s contributions. To address this, every scientist profile included in the ranking underwent manual verification. These profiles were cross-correlated with publications listed in a broad spectrum of trustworthy and authoritative sources to ensure accuracy and reliability.
While the number of papers published in prominent journals and conference proceedings does not directly influence the ranking position, it serves as a valuable secondary indicator of a scientist’s contribution within their specific area of Earth Science research.
The final position in the ranking is established using each researcher’s D-index, based on information rigorously compiled from OpenAlex and CrossRef. These platforms represent the leading bibliometric databases of their kind available to the global research community.
