UPDATE #2: IN CONJUNCTION WITH THE PLANNED SUNSETTING OF DEFENSE
METEOROLOGICAL SATELLITE PROGRAM (DMSP) INITIATED BY THE PROGRAM   S OWNER
AND FOLLOWING THE STEPS OF OTHER PROGRAM STAKEHOLDERS, THE FLEET NUMERICAL
METEOROLOGY AND OCEANOGRAPHY CENTER
 (FNMOC) HAS ANNOUNCED PLANS
TO CEASE DISTRIBUTION DATA FROM THE DEFENSE METEOROLOGICAL SATELLITE
PROGRAM (DMSP) F16, F17, F18 CONSTELLATION EFFECTIVE JULY 31, 2025. AT THAT
TIME, NOAA WILL NO LONGER BE IN RECEIPT OF THE DMSP DATA AND PRODUCTS. FOR
MORE INFORMATION REGARDING DMSP,  PLEASE REACH OUT TO CHIEF OF NAVAL
INFORMATION: CHINFONEWSDESK@US.NAVY.MIL



UPDATE #1: IMPORTANT UPDATE FNMOC PLANS TO CEASE DMSP PROCESSING NO LATER
THAN JULY 31, 2025.


TOPIC: SUSPENSION OF ALL DEFENSE METEOROLOGICAL SATELLITE PROGRAM (DMSP)
DATA BY JULY 31, 2025


DATE/TIME ISSUED: JULY 1, 2025 1815 UTC


PRODUCT(S) OR DATA IMPACTED:  ALL DEFENSE METEOROLOGICAL SATELLITE PROGRAM
(DMSP) DATA AND PRODUCTS: FINE, SMOOTH AND HOUSEKEEPING DATA FROM
OPERATIONAL LINESCAN SYSTEM (OLS), SPECIAL SENSOR MICROWAVE IMAGER SOUNDER
(SSMIS), AND ALL NEAR-EARTH SPACE WEATHER INSTRUMENTS


DATE/TIME OF INITIAL IMPACT: JULY 31, 2025 0000 UTC


DATE/TIME OF EXPECTED END: NA - TERMINATION


LENGTH OF OUTAGE:  SEE DETAILS.


DETAILS/SPECIFICS OF CHANGE:

DUE TO RECENT SERVICE CHANGES, THE DEFENSE METEOROLOGICAL SATELLITE PROGRAM
(DMSP) AND NAVY   S FLEET NUMERICAL METEOROLOGY AND OCEANOGRAPHY CENTER
(FNMOC) WILL DISCONTINUE INGESTING, PROCESSING AND DISTRIBUTION OF ALL DMSP
DATA TO NOAA NO LATER THAN JULY 31, 2025.  ESPC INTERFACES WILL NOT RECEIVE
DMSP DATA AND ALL DATA PRODUCTS WILL BE SUSPENDED. USERS SHOULD EXPECT ALL
FINE, SMOOTH AND HOUSEKEEPING DATA FROM OPERATIONAL LINESCAN SYSTEM (OLS),
SPECIAL SENSOR MICROWAVE IMAGER SOUNDER (SSMIS), AND ALL NEAR-EARTH SPACE
WEATHER INSTRUMENTS TO BE TERMINATED. THIS SERVICE CHANGE AND TERMINATION
WILL BE PERMANENT.


THE DMSP IS A SINGLE DATASET IN A ROBUST SUITE OF HURRICANE FORECASTING AND
MODELING TOOLS IN THE NATIONAL WEATHER SERVICE (NWS)  PORTFOLIO. THE
CURRENT MODELS CONTINUE TO INCLUDE DATA FROM:

   -

   GOES AND OTHER GEOSTATIONARY EARTH-OBSERVING SATELLITES
   -

   POLAR-ORBITING SATELLITES, INCLUDING JOINT POLAR SATELLITE SYSTEM (JPSS)
   AND EUMETSAT METOP
   -

   HURRICANE HUNTER AIRCRAFT RECONNAISSANCE MISSIONS AND OTHER
   AIRCRAFT-BASED OBSERVATIONS
   -

   OBSERVATIONS ON THE GROUND AND FROM BUOYS
   -

   RADIOSONDES AND SUPPLEMENTAL UPPER AIR SOUNDINGS
   -

   GROUND-BASED WEATHER RADAR SITES IN THE U.S. AND NEIGHBORING COUNTRIES



IN PARTICULAR, THE ADVANCED TECHNOLOGY MICROWAVE SOUNDER (ATMS), CURRENTLY
FLYING ON NOAA   S JOINT POLAR SATELLITE SYSTEM (JPSS) TO INCLUDE SNPP,
NOAA-20, NOAA-21), PROVIDES THE RICHEST, MOST ACCURATE SATELLITE WEATHER
OBSERVATIONS AVAILABLE. NOAA   S DATA SOURCES ARE FULLY CAPABLE OF PROVIDING
A COMPLETE SUITE OF CUTTING-EDGE DATA AND MODELS THAT ENSURE THE
GOLD-STANDARD WEATHER FORECASTING THE AMERICAN PEOPLE DESERVE.


CONGRESS VOTED TO TERMINATE THE DMSP PROGRAM AS FAR BACK AS 2015 AND DMSP
WILL BE REPLACED BY THE WEATHER SYSTEM FOLLOW-ON MICROWAVE (WSF-M) AND THE
ELECTRO-OPTICAL/INFRARED WEATHER SYSTEM (EWS).  DMSP SATELLITES REMAIN
OPERATIONAL TODAY BUT ARE MORE THAN A DECADE PAST THEIR EXPECTED END OF
LIFE. WHILE THE DISCONTINUATION OF CERTAIN DATA STREAMS FROM DMSP MAY SEEM
ALARMING, THE TRANSITION TO WSF-M AND EWS REPRESENTS A MODERNIZATION EFFORT
AIMED AT PROVIDING MORE RESILIENT AND ENHANCED ENVIRONMENTAL MONITORING
CAPABILITIES TO IMPROVE OUR ABILITY TO UNDERSTAND AND PREDICT WEATHER
PHENOMENA, INCLUDING TROPICAL CYCLONES. THE FIRST WEATHER SYSTEM FOLLOW-ON
    MICROWAVE (WSF-M) SATELLITE LAUNCHED IN 2024 AND BECAME OPERATIONAL IN
APRIL 2025. WSF-M PROVIDES ENHANCED OCEAN SURFACE VECTOR WIND AND TROPICAL
CYCLONE INTENSITY CAPABILITIES. WSF-M HAS REACHED INITIAL OPERATIONAL
CAPABILITY (IOC) AND INITIAL DATA IS BEING DELIVERED TO DOD USERS. THE DOD
IS WORKING TOWARDS FULL OPERATIONAL CAPABILITY (FOC) WHICH INCLUDES THE
TECHNICAL WORK TO SEND THE DATA TO NOAA AS SOON AS POSSIBLE. DOD USERS
(INCLUDING THE NAVY) WILL CONTINUE TO RECEIVE AND OPERATIONALLY USE DMSP
DATA SENT TO DOD WEATHER SATELLITE    DIRECT READOUT TERMINALS    ACROSS THE
DOD.
