The 1st edition of Research.com ranking of the best scholars in the
arena of Earth Science is based on data
derived from various data sources including OpenAlex and
CrossRef. The bibliometric data for estimating the citation-based metrics were
gathered on 06-12-2021. Position in the ranking is based on a
scholar’s D-index (Discipline H-index), which
only includes papers and citation
data for an examined discipline.

The scope of our Earth Science research
Our best scholars ranking is a credible
account of leading scholars from the discipline of
Earth Science, based on a detailed
study of 166,880 researchers identified
from various bibliometric data sources. For the field of
Earth Science, over 6742 researchers were
investigated.
What is D-index acceptance threshold for Earth Science
The D-index threshold for including a researcher to be
examined is established at 30 if
the majority of of their publications are in the discipline of Earth Science. The
approval factors for scientists to be
considered into the ranking of top researchers are based on the D-index, ratio
of the contributions made within the given area
as well as the awards and achievements of the researchers. The
D-index threshold for listing best researchers is
set as an increment of 10 depending on the total number of researchers
projected for each scientific field whilst
guaranteeing that the top 1% of leading researchers are
considered into the list. We expect a proximity of
30% or less between a researcher’s general H-index and their D-index.
Other verification practices
Since our primary goal is to guarantee that only
genuine scientists are included in
our ranking we are aware that raw data are never
supposed to be a full measure to assess the
work of researchers. Because of that
we manually check every profile and cross-correlate it against publications in a
wide range of reliable sources. While it’s not a
factor defining a scientist’s position in
the ranking, the amount of papers published in
well-known journals and conference proceedings should be a
reliable secondary signal of their contribution to research in a
selected field of study. Position in the ranking is
based on every scholar’s D-index
using data collected from OpenAlex and
CrossRef, which are the most trustworthy and well-established bibliometric
databases of this type accessible to the research community. A
comprehensive overview of our research policy
can be found on our
methodology page.
Our mission
Our goal is to inspire scholars,
businessmen and politicians
around the world to explore where prominent experts are heading
and to provide an opportunity for the whole scientific community to
discover who the leading experts in specific
fields of research, in different countries, or even within research
institutions are.
