Each strip is that field's whole ranked pool, with the notch where NILU sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no average mark, because the average differs by field (from about 6% in Dentistry to 21% in Economics).

Which fields of science does NILU work in?

In 2022-now, 83% of research at NILU is in Physical Sciences, 7% in Social Sciences. Its largest fields are Environmental Science (44%), Earth and Planetary Sciences (17%), Engineering (14%). It does 2.1× the world's share of Physical Sciences.
