The 2nd edition of Research.com ranking of the best universities in the field
of Environmental Sciences was created using data combined from
various data sources including OpenAlex and CrossRef. The bibliometric data for
devising the citation-based metrics were acquired on 21-12-2022.
Position in the ranking is based on a sum of D-indexes (Discipline H-index) of all ranking
researcher’s affiliated with a given institution. D-index
takes into account only papers and citation
metrics for an examined discipline.
The range of our Environmental Sciences research
Research.com’s best universities ranking is a reliable account of leading researchers from the discipline of Environmental Sciences , based on a detailed examination of 166,880 researchers determined from a variety of bibliometric data sources. For the discipline of Environmental Sciences, more than 11258 researchers were analysed.
What is D-index inclusion threshold for Environmental Sciences
The D-index threshold for approving a researcher to be examined is set to 30 if most of their publications are in the discipline of Environmental Sciences. The acceptance criteria for scientists to be considered into the ranking of top researchers are based on the D-index, proportion of the publications made within the given area in addition to the awards and achievements of the scholars. The D-index threshold for including top scholars is set as an increment of 10 depending on the total number of researchers estimated for each area od study whilst ensuring that the top 1% of best researchers are considered into the list. We estimate a proximity of 30% or less between a scholar’s general H-index and their D-index.
Extra verification practices
Because our main aim is to ensure that only credible scientists are included in our ranking we are aware that raw data are never meant to be an absolute means to evaluate the work of scholars. Because of that we manually inspect every profile and cross-correlate it against publications in a broad range of reliable sources. Even though it’s not a metric impacting a scientist’s position in Research.com ranking, the quantity of documents published in major journals and conference proceedings should form a credible secondary indication of their contribution to research in a specific area of science. Position in the ranking is based on every researcher’s D-index according to data gathered from OpenAlex and CrossRef, which are the most trustworthy and well-established bibliometric databases of this kind open to the scientific community. A comprehensive explanation of our research policy can be found on our methodology page.
Our goal is to motivate researchers, businessmen and administrative bodies around the world to investigate where top experts are heading and to give a way for the whole research community to find out who the leading experts in specific fields of research, in various countries, or even within research institutions are.
