The 2nd edition of Research.com ranking of the best researchers in the
field of Environmental Sciences relies os data
derived 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 scientist's
D-index (Discipline H-index), which only includes
publications and citation data for an examined discipline.
The range of our Environmental Sciences research
Research.com’s best researchers ranking is a reliable list of leading scholars from the field of Environmental Sciences, created using a meticulous examination of 166,880 scholars determined from multiple bibliometric data sources. For the field of Environmental Sciences, as many as 11258 researchers were analysed.
What is D-index inclusion threshold for Environmental Sciences
The D-index threshold for including a researcher to be evaluated is set to 30 if the majority of of their publications are in the discipline of Environmental Sciences. The acceptance requirements for scholars to be considered into the ranking of top scientists are based on the D-index, ratio of the publications made within the specific area plus the awards and achievements of the scientists. The D-index threshold for considering best scientists is set as an increment of 10 depending on the total number of scholars estimated for each area od study whilst ensuring that the top 1% of leading scientists are considered into the list. We expect a proximity of 30% or less between a scholar’s general H-index and their D-index.
Extra verification practices
Because our primary aim is to guarantee that only genuine scientists are listed in Research.com ranking we are aware that raw data are never meant to be a complete measure to assess the contributions of scholars. This is why we manually inspect every profile and cross-correlate it against publications in a wide range of trustworthy sources. While it’s not a metric impacting a researcher’s position in Research.com ranking, the quantity of papers published in well-known journals and conference proceedings should form a credible secondary signal of their contribution to research in a selected discipline. Position in the ranking is determined by every scholar’s D-index with the help of metrics compiled from OpenAlex and CrossRef, which are the most trustworthy and well-known bibliometric databases of this kind available to the research community. A thorough definition of our research process can be found on our methodology page.
Our objective is to inspire scholars, companies and politicians worldwide to examine where prominent experts are heading and to offer a way for the whole research community to get to know who the leading experts in specific areas of study, in different countries, or even within research institutions are.
