In the characteristics of ASE, it is written:Quadrangle Distance-Weighted Interpolation TechnologyNew intelligent interpolation fills gaps in weather data more realistically than ever before. The 4 closest data stations in each 90-degree directional quadrant are analyzed and weighted against distance, significantly increasing depiction accuracy in areas with few (or no) reportsWell, what happens if one of those four stations transmits a metar wrong?It is automatically excluded?It is canceled?It creates a conflict with the other stations?

Hi,The wrong data will be used and blended in with the other data. We have no way to double check every piece of data, every hour, for every station. If we have the data wrong so will some of the official data sites such as NOAA.
