Examination of various-order adjoint-based approximations of observation impact

The necessity, and potential implications, of considering higher-than-first-order approximations of the impact of observations on numerical weather forecasts are investigated. In particular, clarification is sought on issues raised by Errico (2007) concerning the interpretation of an adjoint-based m...
