The 2nd edition of Research.com ranking of the best researchers in the
discipline of Environmental Sciences is based on data
consolidated from various data sources including OpenAlex and
CrossRef. The bibliometric data for evaluating the citation-based metrics were
acquired on 21-12-2022. Position in the ranking is based on a
researcher’s D-index (Discipline H-index), which
takes into account only papers and citation
metrics for an examined discipline.
The scope of our Environmental Sciences research
Research.com’s best researchers ranking is a reliable lineup of leading scientists from the field of Environmental Sciences, based on a detailed examination of 166,880 scholars identified from a variety of bibliometric data sources. For the area of Environmental Sciences, more than 11258 researchers were investigated.
What is D-index inclusion threshold for Environmental Sciences
The D-index threshold for approving a researcher to be evaluated is established at 30 if most of their publications are in the discipline of Environmental Sciences. The acceptance criteria for scholars to be considered into the ranking of top researchers are based on the D-index, proportion of the publications made within the selected area as well as the awards and achievements of the researchers. The D-index threshold for listing top scholars is set as an increment of 10 depending on the overall number of scholars estimated for each scientific field whilst guaranteeing that the top 1% of best researchers are considered into the ranking. We expect a proximity of 30% or less between a scholar’s general H-index and their D-index.
Other verification methods
Since our main aim is to ensure that only credible researchers are listed in our ranking we are aware that raw data are never supposed to be an absolute means to evaluate the output of scholars. Because of that we manually check each profile and cross-correlate it against publications in a wide range of credible sources. Even though it’s not a factor impacting a scientist’s position in our ranking, the amount of documents published in well-known journals and conference proceedings should constitute a reliable secondary signal of their contribution to research in a selected field of study. Position in the ranking is determined by each scholar’s D-index using information compiled from OpenAlex and CrossRef, which are the most credible and well-known bibliometric databases of this kind available to the research community. A thorough overview of our research policy can be found on our methodology page.
Our goal is to motivate scholars, companies and politicians around the world to investigate where top experts are heading and to offer a way for the whole scientific community to discover who the leading experts in specific disciplines, in different countries, or even within research institutions are.
