Abstract: Height innovation data for a 2-month period from NOGAPS was analyzed to obtain height prediction and observation error covariances. Different methods of weighting the data in least squares approximations of the spatial ...

Abstract: The sensitivity of multivariate optimum interpolation to variations in values of its parameters is investigated, including missing observation values. The influence of observation error misspecification and parameters in ...

Abstract: The errors in objective analysis methods that are based on corrections to first-guess fields are considered. An expression that gives a decomposition of an error into three independent components is derived. To test the ...

Abstract: An iterative (successive correction) method for objective analysis due to Bratseth is considered. The method converges to the statistical interpolation result in the limit. The properties of the scheme and a variant of it ...

Abstract: This article gives the details and results of an investigation into the properties of the temperature and relative humidity errors from the Navy Operational Global Atmospheric Prediction System for a 4-month period from ...
