-The key differences between MEI version 2 and version 1 are the input variables used, the source of the data, and the dates of the historical record.  MEI version 2 relies on reanalysis data using modern numerical weather models to process and combine historical weather observations into a comprehensive, globally complete, and consistent dataset of past weather and climate and satellite data. This eliminates inconsistencies caused by relying on potentially less reliable ship observations, especially in earlier decades. The switch from cloud cover fraction to Outgoing Longwave Radiation (OLR) provides a more direct and accurate measurement of atmospheric convection, a critical component of ENSO.  Despite the differences in input data, MEI version 2 and the original MEI version 1 are very highly correlated for the overlapping period.
