ECMWF/GEWEX Workshop on Humidity Analysis

The ECMWF/GEWEX Workshop on Humidity Analysis was held at ECMWF from 8 to 11 July 2002.


The Workshop addressed background error covariance modelling, diagnosis and correction of biases in the data and in the model, the accuracy of radiative transfer observation operators (with respect to humidity), and the interactions between the humidity and the mass/wind analyses due to dynamical and physical effects.
