Top 20 Institutions

The top institutions ranked by number of citations are NASA with 16,986, and the Jet Propulsion Laboratory with 11,930 cites. These institutions are the world's largest players in terms of spacecraft design, construction, launch, and science operations. The University of Arizona is the highest-placed research university. The French research council CNRS and the Observatoire de Paris have a joint tally of 14,713.

For numbers of papers the running order is again NASA, JPL, Arizona, and CNRS. Planetary exploration in the UK is largely down to Imperial College London and UCL.

Ranked by citations per paper, the US Geological Survey, whose geological maps of Mars are much in demand, heads the lineup.

About The Institutions



The resulting database contained 3,761 institutions. Ranked by three separate measures: citations, papers, and citations per paper. Source dates: January 1, 2001-March 18, 2011. *Unless otherwise specified, all rankings have a >= 5 paper threshold for all measures.

Overall General Information


 
Regarding Top 20 Scientists, Institutions, Journals, & Nations

Citation tables allow us to map compelling trends:

  • Are there particular nations or institutions that might be expected to dominate research in the Topic area, and do the numbers bear out these expectations, or are there surprises?
  • Who are the leading scientists and where are they located?

While these tables cannot offer a complete picture, the number of trends and anomalies that can be spotlighted or connected across categories is striking. The tables often lead to renewed perspectives to further explore and validate.

What are Special Topics?



Special Topics, from ScienceWatch.com, is designed to complement Essential Science IndicatorsSM from Thomson Reuters in providing citation analyses and commentary for selected scientific research areas that have experienced notable recent advances or are of special current interest.
