A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a refined metric that considers only papers and citations pertinent to the examined discipline—Environmental Sciences in this case. This approach ensures that the ranking accurately reflects a researcher’s impact and contributions strictly within their specialized field.
Scope of Research and Inclusion Criteria
The ranking methodology involved the examination of a total of 279,971 scientist profiles sourced from a diverse array of bibliometric databases encompassing all academic disciplines, of which 1,974 scientists specialized in Environmental Sciences were specifically analyzed. To qualify for inclusion in the ranking, a researcher was required to have a D-index of at least 30 and a majority of their tier publications had to be specifically within the domain of Environmental Sciences.
In addition to bibliometric thresholds, scientists’ notable awards and achievements within the field were incorporated as qualitative factors to ensure a well-rounded evaluation of their scholarly contributions.
The D-index threshold is calibrated in increments of 10 relative to the estimated total number of scholars per discipline, while ensuring that the top 1% of leading experts are captured within the ranking. Furthermore, to maintain disciplinary relevance, there is a stipulation that the difference between a scientist’s general H-index and their D-index should not exceed 30%.
Verification and Validation Procedures
Understanding the inherent limitations of raw bibliometric data, the Research.com team employed rigorous manual verification techniques to complement automatic data aggregation. Each scientist profile was carefully cross-correlated against publications indexed in a broad spectrum of trusted sources to authenticate the accuracy of affiliations, publication records, and citation counts.
While the number of publications in prominent journals and conference proceedings is not directly factored into a researcher’s ranking position, it is recognized as an important secondary signal of their contributions to advancing knowledge in specific scientific domains.
The ranking positions are officially determined based on each researcher’s D-index derived from OpenAlex and CrossRef—the most prominent and authoritative bibliometric databases available to the global research community.
