The 2nd edition of Research.com ranking of the best universities in the arena of
Environmental Sciences was created using data consolidated from
multiple data sources including OpenAlex and CrossRef. The bibliometric data for
estimating 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
only includes publications and citation
data for an examined discipline.
The focus of our Environmental Sciences research
Research.com’s best universities ranking is a credible list of leading scholars from the field of Environmental Sciences, created using a meticulous study of 166,880 scientists determined from multiple bibliometric data sources. For the field of Environmental Sciences, over 11258 scholars were examined.
What is D-index approval threshold for Environmental Sciences
The D-index threshold for including a researcher to be evaluated is placed at 30 if most of their publications are in the field of Environmental Sciences. The inclusion requirements for scientists to be considered into the ranking of top scholars are based on the D-index, ratio of the contributions made within the specific field of study plus the awards and achievements of the researchers. The D-index threshold for listing best researchers is set as an increment of 10 depending on the overall number of scholars estimated for each scientific field whilst ensuring that the top 1% of leading researchers are considered into the ranking. We expect a proximity of 30% or less between a scientist’s general H-index and their D-index.
Other verification methods
Because our main mission is to ensure that only genuine scholars are mentioned in Research.com ranking we believe that numbers are never supposed to be a complete measure to evaluate the work of researchers. This is why we manually verify each profile and cross-correlate it against publications in a varied range of reliable sources. Even though it’s not a factor defining a scholar’s position in Research.com ranking, the amount of papers published in major journals and conference proceedings should form a valuable secondary signal of their contribution to research in a specific field of study. Position in the ranking is established using each researcher’s D-index according to metrics collected from OpenAlex and CrossRef, which are the most prominent and well-established bibliometric databases of this type accessible to the scientific community. A thorough explanation of our research process can be found on our methodology page.
Our aim is to motivate scientists, businessmen and administrative bodies worldwide to investigate where leading experts are heading and to give an opportunity for the whole scientific community to get to know who the leading experts in specific areas of study, in various countries, or even within research institutions are.
