The 2nd edition of Research.com ranking of the best universities in the field of
Environmental Sciences is based on data combined from
multiple data sources including OpenAlex and CrossRef. The bibliometric data for
evaluating the citation-based metrics were collected on 21-12-2022. Position
in the ranking is based on a sum of D-indexes (Discipline H-index) of all ranking
scientist's affiliated with a given institution. D-index
takes into account only publications and citation
values for an examined discipline.
The range of our Environmental Sciences research
Research.com’s best universities ranking is a reliable list of leading researchers from the area of Environmental Sciences, based on a meticulous examination of 166,880 scientists discovered from various bibliometric data sources. For the field of Environmental Sciences, over 11258 researchers were examined.
What is D-index approval threshold for Environmental Sciences
The D-index threshold for including a researcher to be considered is set to 30 if the majority of of their publications are in the field of Environmental Sciences. The inclusion requirements 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 area as well as the awards and achievements of the scholars. The D-index threshold for including leading researchers is set as an increment of 10 depending on the overall number of researchers estimated for each discipline whilst making sure that the top 1% of leading scientists are incorporated into the ranking. We expect a proximity of 30% or less between a scientist’s general H-index and their D-index.
Additional verification methods
Since our leading aim is to ensure that only actual scientists are mentioned in Research.com ranking we are aware that numbers are never meant to be an absolute tool to evaluate the contributions of scholars. For that reason we manually verify each profile and cross-correlate it against publications in a wide range of trustworthy sources. While it’s not a metric contributing to a scientist’s position in Research.com ranking, the quantity of documents published in major journals and conference proceedings should constitute a valuable secondary implication of their contribution to research in a selected discipline. Position in the ranking is based on each scholar’s D-index using data compiled from OpenAlex and CrossRef, which are the most trustworthy and well-known bibliometric databases of this kind accessible to the research community. A comprehensive explanation of our research procedures can be found on our methodology page.
Our goal is to inspire researchers, entrepreneurs and politicians around the world to investigate where top experts are heading and to offer a way for the whole scientific community to get to know who the leading experts in specific areas of study, in different countries, or even within research institutions are.
