The 1st edition of Research.com ranking of the best researchers in the
arena of Environmental Sciences is based on data
consolidated from various data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
collected on 06-12-2021. Position in the ranking is based on a
scientist's D-index (Discipline H-index), which
takes into account only publications and citation
data for an examined discipline.

The focus of our Environmental Sciences research
Research.com’s best scientists ranking is a credible
account of leading scholars from the area of
Environmental Sciences, created using a meticulous
study of 166,880 scientists determined
from a variety of bibliometric data sources. For the area of
Environmental Sciences, more than 9206 scientists were
investigated.
What is D-index inclusion threshold for Environmental Sciences
The D-index threshold for approving a scholar to be
evaluated is established at 30 if
most of their publications are in the discipline of Environmental Sciences. The
approval criteria for scholars to be
considered into the ranking of top scientists are based on the D-index, proportion
of the contributions made within the selected discipline
in addition to the awards and achievements of the scholars. The
D-index threshold for considering top scientists is
set as an increment of 10 depending on the total number of researchers
estimated for each discipline whilst
guaranteeing that the top 1% of best scientists are
added into the list. We expect a proximity of
30% or less between a scientist’s general H-index and their D-index.
Other verification methods
Because our primary aim is to guarantee that only
actual researchers are listed in
the ranking we realize that numbers are never
meant to be a complete measure to assess the
contributions of scholars. For that reason
we manually verify every profile and cross-correlate it against publications in a
varied range of trustworthy sources. While it’s not a
element impacting a scientist’s position in
Research.com ranking, the amount of papers published in
major journals and conference proceedings should constitute a
credible secondary signal of their contribution to research in a
given field of study. Position in the ranking is
established using every researcher’s D-index
according to information gathered from OpenAlex and
CrossRef, which are the most credible and well-known bibliometric
databases of this type accessible to the research community. A
detailed overview of our research process
can be found on our
methodology page.
Our agenda
Our goal is to motivate scientists,
entrepreneurs and administrative bodies
worldwide to examine where top experts are heading
and to offer a way for the entire research community to
find out who the leading experts in specific
fields of research, in various countries, or even within research
institutions are.
