In a few cases there could be an apparent discrepancy between EFI values as indicated by the ecChart probe tool and the CDF curve for the same selected location. This is because the EFI and CDF may use different but nearby grid points. The discrepancy, however, is rarely significant.
The M-climate on the CDF plot should only be considered as a reference so is not suitable for accurate calculations of EFI and SOT. The M-climate is lead-time dependent and there might be differences for different lead-times, especially in the tails of the CDF Plotplot.
