"The presence of this offset in newer data makes it inappropraite to (naively) compare data from before and after the baseline change. Trying to apply a machine learning model trained on the old baseline to (unadjusted) imagery from the new baseline will yield incorrect results. And trying to train a machine learning model on old and (unadjusted) new data will likely result in much worse performance.\n",
