During a House Science, Space and Tech Committee hearing in July, Rep. Scott Franklin (R-FL) spoke about a plan the Pentagon floated, but later retracted, that would stop hurricane data sharing with the National Oceanic and Atmospheric Administration.

00:00I thank the witnesses for their testimony, and I now recognize myself for five minutes for questions.
00:05As I mentioned previously, my home state of Florida is no stranger to hurricanes.
00:09We all know that.
00:10My hometown, as I said, has the Hurricane Hunters based at Lakeland Airport.
00:14Miami is the home of the National Hurricane Center.
00:16They even named the University of Miami after the hurricane.
00:19So we're very versed in hurricanes.
00:22Unfortunately, we have way too much practice, and we have had a lot of practice in preparation and resilience,
00:27and we've gotten better at that over the years.
00:29And a lot of that's been driven by the forecast and the better and better forecasts we're getting.
00:33As we've experienced the last few years, we're seeing a lot of these hurricanes intensify rapidly,
00:38sometimes from a Cat 1 or a Cat 2 to a 4 or 5 even overnight.
00:42So timing is critical, and best predictions of where they're going to make landfall are important.
00:47When you have basically a thumb sticking out in the Gulf of Mexico, Gulf of America,
00:51that's got 24 million people, where that storm makes landfall is critical on how we determine
00:56how we evacuate millions of people away from the coast.
01:00So on that, originally planned for 2026, but moved up to July of 2025,
01:05DOD announced that it's going to discontinue the ingestion, processing, and distribution
01:10of all Defense Meteorological Satellite Program, DMSP data to NOAA, citing security concerns.
01:17And there are some valid security concerns there, and national security is important,
01:21but these sensors have been critical to determining storm centers, especially at night.
01:26To all of our witnesses, and if we could, since there's four of you and I've got five minutes,
01:30if you could try to limit it to maybe 30 seconds,
01:31what can be done to best supplement this DMSP data moving forward as the program is phased out?
01:37And then also, in your opinion, is DOD living up to its commitments after the cancellation of NPO's
01:43to gather and provide early morning orbit coverage to complement NOAA's joint polar satellite system?
01:50Mr. Cavett, if you could lead off.
01:53Thank you, Mr. Chairman.
01:54Well, let me first start by saying that microwave imagers and microwave sounders,
01:59microwave imagers is the type of sensor that's on DMSP,
02:01are critically important for hurricane forecasting,
02:04but also just the backbone of our numerical weather prediction,
02:06kind of medium-range forecasting capabilities.
02:09So the loss of that system is significant.
02:12If you couple that with the shutdown of the POSE systems from NOAA in June of this year,
02:17we've lost about 60% of our capacity as a nation for microwave imagers and sounders,
02:23which is quite a high number.
02:26Tomorrow.io actually has seven microwave sounders on orbit today,
02:29providing that operational data.
02:31And while the imagers and the sounders, there's some nuances to the sort of differences in them,
02:35they both really provide that early detection of intensification that you mentioned,
02:40being able to see the eye formation, the curve band before that,
02:44and at night as well, as you said,
02:46because the geostationary sensors can only see the cloud tops
02:50and sort of infer what's happening within the storm.
02:53In terms of whether DOD is meeting its mission to provide that early morning orbit,
02:57WSFM, which is the weather system follow-on microwave,
03:00which they launched in 2024, is in that orbit,
03:04but it's not the exact copy of SSMIS on DMSP.
03:08It's a slightly different frequency range.
03:10NOAA is also launching their quick sounder program potentially in 2026,
03:15and together those would fill that early morning gap for the most part.
03:19But I'll also say that this concept of kind of early morning,
03:23early afternoon architecture is a bit outdated.
03:27If you compare what our constellation is capable of today,
03:30because we fly in both polar and mid-latitude orbits,
03:33we actually achieve two-hour revisit globally throughout the day.
03:38So this idea of kind of spacing your sensing throughout the day is irrelevant
03:42when you can meet a sub-hourly revisit,
03:45which is what we'll achieve by the end of this year.
03:47So I think it's important in terms of filling these gaps to your question
03:51that NOAA be able to access these data sets,
03:54particularly as we're entering this severe hurricane season this year.
03:59Dr. Nielsen-Gammon.
04:00I'll just comment that having a smooth transition of observing system
04:03is critical for being able to optimize the technology and how we use it.
04:07I'll let the satellite experts talk in more detail.
04:10Dr. Abdellabi.
04:12I'll reiterate that comment.
04:14There are some capabilities.
04:16We use these in the Arctic for monitoring sea ice evolution as well.
04:22I'm not as familiar with the meteorological applications,
04:26but what is critical with satellite capabilities is overlap.
04:30And my understanding is the end of life of DMSP is about a year away,
04:35so it isn't clear to me why there –
04:37well, if there are security concerns, I defer to those experts.
04:40But it comes at a great cost because that overlap and cross-calibration,
04:46time is needed for that,
04:48and we're losing that time for reasons I don't understand.
04:52All right.
04:52Dr. Gupta.
04:53I will reiterate, like, long horizon archives are fairly important,
04:58and as we change observational systems,
05:01you need to have them overlapping for ideally at least a year
05:04to complete the full season.
05:07Great.
05:07All right.
05:08I now recognize the ranking member from Rhode Island
05:11for five minutes of questions.
