A technique to improve the quality of accumulated fields

The accumulation of gridded fields over long time intervals can greatly magnify the impact of any noise in the individual grids. This paper describes a quality control method for reducing this noise in accumulation grids by taking advantage of both spatial and temporal coherence. In order to quantify the improvements in the accumulated grids and explain the effects of various parameters, the method is applied to simulated data. The quality control technique is then applied to a few illustrative real-world datasets.
