The 2nd edition of Research.com ranking of the best scholars in the
discipline 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
gathered on 21-12-2022. Position in the ranking is based on a
researcher’s D-index (Discipline H-index), which
includes exclusively papers and citation
values for an examined discipline.

The scope of our Environmental Sciences research
Research.com’s best scientists ranking is a trustworthy
list of leading researchers from the area of
Environmental Sciences, created using a detailed
study of 166,880 scholars discovered
from various bibliometric data sources. For the area of
Environmental Sciences, more than 11258 scientists were
analysed.
What is D-index acceptance threshold for Environmental Sciences
The D-index threshold for including a scientist to be
examined is established at 30 if
the majority of of their publications are in the area of Environmental Sciences. The
inclusion criteria for scientists to be
considered into the ranking of top scholars are based on the D-index, ratio
of the contributions made within the selected area
plus the awards and achievements of the scholars. The
D-index threshold for considering top researchers is
set as an increment of 10 depending on the overall number of scholars
projected for each area od study whilst
making sure that the top 1% of best scientists are
added into the ranking. We estimate a proximity of
30% or less between a scholar’s general H-index and their D-index.
Additional verification practices
Because our main aim is to guarantee that only
actual scholars are listed in
our ranking we are aware that raw data are never
meant to be a complete tool to assess the
output of scientists. Because of that
we manually verify every profile and cross-correlate it against publications in a
wide range of credible sources. While it’s not a
factor impacting a scientist’s position in
Research.com ranking, the amount of documents published in
major journals and conference proceedings should form a
reliable secondary indication of their contribution to research in a
selected area of science. Position in the ranking is
determined by every researcher’s D-index
according to data collected from OpenAlex and
CrossRef, which are the most prominent and well-known bibliometric
databases of this kind accessible to the research community. A
detailed definition of our research policy
can be found on our
methodology page.
Our agenda
Our aim is to motivate researchers,
businessmen and administrative bodies
worldwide to explore where prominent experts are heading
and to give an opportunity for the whole research community to
discover who the leading experts in specific
areas of study, in different countries, or even within research
institutions are.
