The 2nd edition of Research.com ranking of the best scientists in the
field of Environmental Sciences was created using data
combined from multiple data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected on 21-12-2022. Position in the ranking is based on a scholar’s
D-index (Discipline H-index), which takes into account only
publications and citation values for an examined discipline.
The range of our Environmental Sciences research
Research.com’s best researchers ranking is a trustworthy account of leading scholars from the field of Environmental Sciences, created using a thorough study of 166,880 researchers discovered from multiple bibliometric data sources. For the area of Environmental Sciences, as many as 11258 researchers were examined.
What is D-index approval threshold for Environmental Sciences
The D-index threshold for accepting a scientist to be examined is placed at 30 if the majority of of their publications are in the area of Environmental Sciences. The acceptance criteria for scientists to be considered into the ranking of top scientists are based on the D-index, ratio of the contributions made within the selected field of study in addition to the awards and achievements of the researchers. The D-index threshold for including best scientists is set as an increment of 10 depending on the total number of researchers projected for each area od study whilst ensuring that the top 1% of leading researchers are considered into the ranking. There should be a proximity of 30% or less between a scientist’s general H-index and their D-index.
Additional verification practices
As our primary mission is to guarantee that only actual scholars are listed in the ranking we realize that numbers are never supposed to be an absolute tool to assess the output of researchers. For that reason we manually verify every profile and cross-correlate it against publications in a varied range of trustworthy sources. While it’s not a element impacting a scientist’s position in Research.com ranking, the number of documents published in major journals and conference proceedings should form a reliable secondary signal of their contribution to research in a specific area of science. Position in the ranking is established using each researcher’s D-index using data compiled from OpenAlex and CrossRef, which are the most prominent and well-established bibliometric databases of this type available to the research community. A detailed overview of our research process can be found on our methodology page.
Our aim is to inspire researchers, companies and administrative bodies around the world to investigate where prominent experts are heading and to provide a way for the entire scientific community to get to know who the leading experts in specific areas of study, in various countries, or even within research institutions are.
