A rain field reconstruction and downscaling methodology is presented, which allows suitable integration of large scale rainfall information and rain-gauge measurements at the ground. The former data ...
Downscaling rainfields in space and time, using the String of Beads model in time series mode
Space-time rainfield modelling
font style='font-size:12px;'>
2009/3/23
The String of Beads model is a space-time model of rainfields measured by weather radar. It is here driven by two auto-regressive time series models, one at the image scale, the other at the pixel sca...
