Data Sources and Bibliometric Collection
The 5th edition of the Research.com Best Earth Science Scientists in Sweden Ranking is based on comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple other authoritative data repositories. The citation metrics and publication records used to calculate the positions within the ranking were collected on January 12, 2026. The ranking methodology hinges on the D-index (Discipline H-index), a refined bibliometric measure that focuses exclusively on a researcher's output and citation impact within the specific discipline of Earth Science. This metric ensures that the evaluation reflects contributions that are discipline-specific rather than a researcher’s overall output across multiple fields.
Scope of Research and Selection Criteria
Our analysis began with an examination of 279,971 scientist profiles drawn from a diverse array of bibliometric databases across all academic disciplines. From this expansive pool, 91 scientists specializing in Earth Science within Sweden were carefully identified. To qualify for inclusion in the ranking, a scientist was required to meet a minimum D-index threshold of 30. Additionally, a majority of their tier publications must be firmly situated in Earth Science. Beyond bibliometric performance, a researcher’s scientific awards and achievements in Earth Science were also taken into account.
The threshold for the D-index is dynamically adjusted in increments of 10 to correspond with the estimated number of scholars within each discipline, ensuring that the ranking system consistently captures the top 1% of leading researchers in that field. Furthermore, to ensure disciplinary consistency, the proximity between a scientist’s general H-index and their D-index is maintained at 30% or less.
Verification and Validation Procedures
Recognizing the limitations inherent in raw bibliometric data, the Research.com team undertook meticulous manual verification of all scientist profiles. This included cross-correlation of publications across a broad spectrum of reputable and trustworthy sources to confirm the accuracy and relevance of identified research outputs. While the number of papers published in prestigious journals and renowned conference proceedings does not influence the ranking position directly, it serves as a valuable secondary indicator of a researcher’s contribution and stature within the Earth Science community.
The order within the ranking is firmly established through the D-index derived using data from OpenAlex and CrossRef, the foremost bibliometric databases available to researchers worldwide.
