 ====== Inverse Distance Squared ======
+☚ WORKING
 Data from 2007.05.31 to 2007.12.31. For every observed value of 24 hour precipitation at a station a model value is calulated at the same point performing an inverse distance squared weighted interpolation over the nearest neighbours.

 ====== Inverse Distance Squared (with Height Correction) ======
-The same algorithm is applied as for normal inverse distance square weighting except that all observations are reduced to a value at sea-level, the interpolation is performed, and the result is scaled back to the interpolated point real altitude.
+The same algorithm is applied as for normal inverse distance square weighting except that all observations are reduced to a modelled value at sea-level, the interpolation is performed, and the result is scaled back to the interpolated point real altitude.
 For all altitudes below 1000 m the precipitation value decreases by 10% per 100m altitude, above 1000m the change is 5% per 100m.
