A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a refined metric that specifically accounts for papers and citations within the examined discipline of Environmental Sciences. This discipline-focused approach allows for an accurate assessment of an individual researcher’s impact and contribution to their specific field.
Scope of Research and Eligibility Criteria
The ranking process began with the examination of 279,971 scientist profiles compiled from a variety of bibliometric data sources, spanning all academic disciplines. From this comprehensive dataset, 15 scientists specializing in Environmental Sciences in Mexico were identified for detailed analysis.
To qualify for inclusion in the ranking, a scientist's D-index had to meet a minimum threshold of 30. Additionally, the majority of their tier publications were required to be within the Environmental Sciences discipline to ensure disciplinary relevance. Awards and notable achievements in Environmental Sciences were also taken into consideration as supplementary indicators of research excellence.
The D-index threshold is dynamically set in increments of 10, reflecting the estimated total number of scholars within each discipline. This adaptive threshold guarantees the inclusion of the top 1% of leading researchers for each field. Furthermore, a proximity rule was applied to maintain scientific precision: a qualifying scientist’s overall H-index must not deviate from their D-index by more than 30%, further validating the discipline-specific focus of the ranking.
Additional Verification Practices
Recognizing the limitations inherent in raw bibliometric data, the team behind this ranking undertook rigorous manual verification of all scientist profiles. Each profile was carefully cross-correlated with publications found in a wide array of trustworthy sources to ensure accuracy and authenticity.
While quantitative factors such as the number of papers published in prominent journals and conference proceedings do not directly determine a researcher’s rank, these outputs serve as valuable secondary signals of a scientist’s influence and contribution to Environmental Sciences research.
The ranking positions are established based on the D-index calculated via data from OpenAlex and CrossRef, the two most prominent and reputable bibliometric databases available to the global research community.
