A Shift in Data Sources<\/h2>\n\n\n\n

NOAA to Stop Using DMSP by End of July<\/h3>\n\n\n\n

The National Oceanic and Atmospheric Administration (NOAA) is making a big change in how it gets important weather information. By July 31, 2025, NOAA will stop using data from the U.S. Department of Defense’s (DOD) Defense Meteorological Satellite Program (DMSP). This program has been very important for weather forecasting, especially for hurricanes, since the 1960s.<\/p>\n\n\n\n

What Made DMSP So Valuable?<\/h3>\n\n\n\n

DMSP provided special microwave data that helped forecasters see inside storms in three dimensions and understand their conditions, even at night.<\/p>\n\n\n\n

Why the Navy Is Ending DMSP<\/h3>\n\n\n\n

The Navy, which manages DMSP, explained its decision by saying the program no longer meets modern technology needs. They also want to reduce cybersecurity risks. This news comes as the United States is in its peak hurricane season. Many meteorologists and scientists are worried that stopping DMSP data could make weather forecasts less accurate. They say that DMSP provides about half of all microwave data, and losing it could create big gaps. This might mean forecasters miss when storms get stronger very quickly, underestimate how strong they are, or even predict their paths incorrectly.<\/p>\n\n\n\n

NOAA’s Confidence and Broader Concerns<\/h2>\n\n\n\n

NOAA Says It Has Strong Alternatives<\/h3>\n\n\n\n

However, NOAA has a different view. The agency says its other data sources are fully capable. These include the Advanced Technology Microwave Sounder (ATMS) on its newer Joint Polar Satellite System (JPSS) satellites (SNPP, NOAA-20, NOAA-21). NOAA sees this change as a normal process of updating and replacing old data sources with new ones.<\/p>\n\n\n\n

New Programs Replacing DMSP<\/h3>\n\n\n\n

In fact, Congress decided to end the DMSP program back in 2015. New programs, like the Weather System Follow-on \u2013 Microwave (WSF-M) and the Electro-Optical\/Infrared Weather System (EWS), are replacing DMSP. The first WSF-M satellite started working in April 2025 and offers improved ways to measure ocean winds and hurricane strength.<\/p>\n\n\n\n

Climate Risks and Equity Concerns<\/h3>\n\n\n\n

This discontinuation also happens at a time when NOAA is reducing its staff, as part of a government plan to cut federal jobs. Some groups that monitor climate are concerned that ending DMSP, along with fewer staff, could increase risks, especially for tracking climate change. There are also wider talks about how previous administrations tried to privatize government weather forecasting. This raises concerns that people who cannot pay for commercial services might have limited access to crucial weather data.<\/p>\n\n\n\n

The Debate Over Forecast Accuracy<\/h3>\n\n\n\n

While NOAA expresses confidence in its remaining tools, the loss of a long-standing data source like DMSP has sparked debate among experts about the future of weather accuracy and data accessibility in the United States.<\/p>\n\n\n\n
