TOPIC: JPSS ALGORITHM UPDATES IN IDPS BLOCK 2.3 MAINTENANCE RELEASE MX15
TRANSITION TO OPERATIONS

DATE/TIME ISSUED:  DECEMBER 2, 2025 1535UTC



PRODUCT(S) OR DATA IMPACTED: ATMS SDR TDR

DATE/TIME OF INITIAL IMPACT: DECEMBER 11, 2025 TBD UTC



DATE/TIME OF EXPECTED END: NA



LENGTH OF IMPACT: NA



DETAILS/SPECIFICS OF CHANGE:

THE EAGERLY ANTICIPATED TRANSITION TO OPERATIONAL STATUS FOR THE CRITICAL
JPSS ALGORITHM UPDATES, WHICH ARE AN INTEGRAL COMPONENT OF THE IDPS BLOCK
2.3 MAINTENANCE RELEASE MX15, HAS BEEN OFFICIALLY POSTPONED. THIS DEFERRAL
MOVES THE OPERATIONAL IMPLEMENTATION DATE FROM ITS PREVIOUSLY SCHEDULED
TIMELINE TO DECEMBER 11, 2025.

THIS UNAVOIDABLE DELAY IS DIRECTLY ATTRIBUTABLE TO AN UNFORESEEN LAPSE IN
APPROPRIATIONS. THIS FUNDING INTERRUPTION HAS CREATED A TEMPORARY BUT
SIGNIFICANT IMPEDIMENT, NECESSITATING A REVISED SCHEDULE FOR THESE CRUCIAL
UPDATES. THE JPSS ALGORITHM UPDATES ARE VITAL FOR ENSURING THE CONTINUED
ACCURACY, RELIABILITY, AND ENHANCEMENT OF DATA PROCESSING AND PRODUCT
GENERATION WITHIN THE JOINT POLAR SATELLITE SYSTEM (JPSS) OPERATIONAL
FRAMEWORK. ONCE IMPLEMENTED, THESE UPDATES ARE EXPECTED TO FURTHER IMPROVE
THE QUALITY AND UTILITY OF ENVIRONMENTAL DATA PROVIDED TO FORECASTERS AND
RESEARCHERS, ULTIMATELY BENEFITING A WIDE RANGE OF APPLICATIONS, FROM
WEATHER PREDICTION TO CLIMATE MONITORING. THE NEW DECEMBER 2ND TARGET DATE
ALLOWS THE NECESSARY RESOURCES AND PERSONNEL TO BE PROPERLY ALIGNED
FOLLOWING THE RESOLUTION OF THE APPROPRIATIONS ISSUE, ENSURING A SMOOTH AND
SUCCESSFUL TRANSITION TO OPERATIONS.
