Kalman filter results

On this page are shown three graphics. Their aim is to show the effect of the Kalman filter applied on the raw data from ECMWF. They are all constructed on the same basis. On the x-axis is the real data measured 5m above ground level at APEX, and the y-axis is the corresponding forecast. In red (diamond) is the raw ECMWF forecast, in green (plus) the Kalman-filtered data, trained over the past 2 weeks. For reference the curve 'y = x' is overplotted.
