Lawless, A. S. ORCID: https://orcid.org/0000-0002-3016-6568 (2010) A note on the analysis error associated with 3D-FGAT. Quarterly Journal of the Royal Meteorological Society, 136 (649). pp. 1094-1098. ISSN 1477-870X doi: 10.1002/qj.619

Abstract/Summary

The analysis-error variance of a 3D-FGAT assimilation is examined analytically using a simple scalar equation. It is shown that the analysis-error variance may be greater than the error variances of the inputs. The results are illustrated numerically with a scalar example and a shallow-water model.
