Sentences with phrase «in neutral density»

Particularly, a comparison with CHAMP neutral gas density observations in the vicinity of Millstone Hill ISR has shown that the retrieved neutral gas densities coincide with the observed ones within the announced accuracy of CHAMP observations, provided that accurate Ne (h) ISR profiles are used for the retrieval.

In this case the agreement with CHAMP neutral gas density observations is less successful (see Fig. 19).
