Comparisons of IRI model and electron density data for the sub-equatorial station, Natal
Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
No Canadian affiliation. An affiliation-only frame — the usual design — would never have seen this work. It is one of the works that make the case for inverting the frame.

Space physics comparison of ionospheric model predictions with electron density observations.
It compares ionospheric observations with a scientific model, not research practice.
Ionospheric model-data comparison at Natal; geophysics, not scholarly research as object.
Abstract
Database from CADI (Canadian Digital Ionosonde) recorded at Natal (5.2degrees S, 36degrees W) near solar maximum are used to compare with the International Reference Ionosphere (IRI) predictions. Such comparison is done using vertical profiles of electron density and F region peak parameters, the maximum electron density (NmF2) and its corresponding height (HmF2), for geomagnetically quiet and disturbed conditions. The mean behavior of the observed vertical electron density profiles at 0300, 0900, 1500 and 2100 UT (UT = LT + 2.4 hr) for quiet and disturbed periods was compared with IRI profiles. Generally, good agreement between the two sets is noted, but IRI underestimates the heights of the bottomside F region at 0900 and 2100 UT. Also, discrepancies are found between the observed values of NmF2 and HmF2 and those obtained from IRI using URSI coefficients during evening-nighttime period.
Stored with the screening record, where it is evidence for the labels above.
