Length of Outage: TBD
Details/Specifics of Change:

Algorithm updates for Build 2.3 Mx 0:
1. ATMS TDR/SDR runtime differences in lunar intrusion regions
The lunar intrusion correction was showing slight differences between the ADL and the IDPS. STAR determined that the root cause of the difference was due to the order of the data packets being processed. The update ensures that the IDPS and ADL process the data in the same order to get similar results.
2. VIIRS SDR Geolocation Algorithm Correction
VIIRS optical model applied in generating VIIRS SDR geolocation products will be improved in IDPS Block 2.3 Mx0. Expected geolocation changes (latitude/longitude) are on a sub-pixel level. Users should only see minor differences in data values or metadata. No actions are required by users.
3. File names will change when put into the Cloud in Block 2.3.
