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 on the ground level at La Silla, and the y-axis the corresponding forecast.
In red (diamond) is the forecast without filter, in orange (plus) the Kalman-filtered data, and for reference is the curve 'y = x' drawn in light green.
