Description

A new global UTH dataset, produced within the framework of the EUMETSAT Satellite Application Facility for Climate Monitoring (CM SAF), is presented. The dataset is based on data from 12 polar-orbiting MW sounders operating at 183 GHz that are combined into a single time series covering the period 06/07/94 to 31/12/18. The data are provided on hourly and daily time steps at 1°x1° lat-long. Uncertainty components that capture sources of random, locally correlated and systematic errors in the data are also provided for each grid cell. These uncertainties have been propagated from the input MW top of atmosphere observations and through the UTH retrieval; uncertainties from the retrieval and the incomplete spatial sampling are also included.
