An error has been discovered in processing the initial batches of V06 IMERG Final Run months. A design choice in the code ended up retaining microwave precipitation estimates in the latitude band 60°N-S when there is snow/ice on the surface, rather than masking out the estimates due to low performance in such cases. [Masking for microwave retrievals over surface snow and ice outside that band is correct.] All V06A Monthly and Half-hourly IMERG products are being retracted, as shown in this table (Encompassing all IMERG V06A data that had been reprocessed and archived -to date): ----------+----...
