Data Sources and Metrics
The 5th edition of the Research.com Best Environmental Sciences Scientists in Taiwan Ranking is grounded in comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple additional reputable databases. These sources provide a robust and granular view of scholarly output and impact across diverse scientific disciplines. The bibliometric data used to devise the citation-based metrics for this ranking were collected on January 12, 2026, ensuring the currency and relevance of the evaluated metrics.
A scientist's ranking position is determined by their Discipline H-index, or D-index, a refined metric that considers only the publications and citation metrics pertinent to the Environmental Sciences discipline. This approach ensures that the ranking accurately reflects a researcher’s influence and contributions within the specific field under examination.
Scope of Research and Eligibility Criteria
The ranking process involved examining 279,971 scientist profiles aggregated from a variety of bibliometric data sources across all academic disciplines. Within this extensive dataset, 38 scientists specializing in Environmental Sciences were specifically identified for consideration. To qualify for this ranking, scientists were required to have a D-index of at least 30. Additionally, a majority of their tier publications had to be anchored within the Environmental Sciences domain, reflecting a focused and sustained contribution to the field.
Scientist awards and field-specific achievements were integrated as qualitative factors complementing the bibliometric data. The D-index threshold is calibrated in increments of 10 according to the estimated total number of scholars within each discipline, ensuring that the ranking encompasses at least the top 1% of leading researchers in Environmental Sciences. Furthermore, eligibility requires that the proximity between a scientist’s overall H-index and their Discipline H-index does not exceed 30%, safeguarding a disciplinary balance and emphasizing specialized impact.
Additional Verification Practices
Recognizing the inherent limitations of raw bibliometric data as sole evaluative tools, the Research.com team conducted manual verification of all scientist profiles. This meticulous cross-correlation incorporates publications across a broad spectrum of trusted sources to confirm the accuracy and relevance of the dataset. While not a direct factor influencing the ranking position, the volume of publications in prestigious journals and conference proceedings is acknowledged as a valuable secondary indicator of a scientist’s scholarly contribution within Environmental Sciences.
The position of each researcher in the ranking is ultimately established using the D-index as calculated from information sourced from OpenAlex and CrossRef, two of the most prominent and well-respected bibliometric databases accessible to the global research community.
