A new option has been added to the accumulate interpolation: "strict". When this is active, if one of the accumulated value is nodata, the whole sum will be set to nodata. Without this option, all values that can be aggregated are aggregated (ie: best effort). When using multiple stations, it might make sense to enable "strict" in order to avoid polluting the spatial interpolation with potentially under-estimated values.

A documentation issue has been fixed in Meteo1DInterpolator.
