The Only Commercial Satellite Weather Data


Critical Weather Data

GPS Radio Occultation (GPS-RO) data “supercharges” forecasting models. Each occultation provides an incredibly accurate depiction of a slice of the atmosphere. When fed into existing models, this data increases short term forecast accuracy.

Fully Processed In-house

Spire has built the world’s first commercial radio occultation processing system. Each of the profiles that you see below were collected with a Spire satellite and processed with Spire’s processing system.



By utilizing a network of tens or hundreds of CubeSats with radio occultation payloads, the number of opportunities to receive radio occultations increases dramatically. Increased RO data points results better forecasts.

You need fresh data no matter what time it is. That is why Spire operates teams on three continents. As the sun begins to set on one operations center, the sun is rising on another.

Extreme Weather on the Rise

Extreme weather threatens both lives and businesses. With the advent of climate change, extreme weather events continue to increase in frequency. Having adequate warning has never been more important.

Ash cloud troubles reignite the argument for better weather forecasting

The volcanic troubles in Hawaii refuse to abate. It has been two weeks since eruptions began at Hawaii’s Kilauea volcano, with the latest gigantic eruption last Thursday sending a further slew of ash 30,000ft (9,100m) into the sky, news that will cause consternation for a global airline industry that has been here before. You may remember Iceland 2010, when almost 20 countries closed their airspace to commercial aircraft traffic, affecting circa 10 million travellers over ash concerns. Volcanic ash plays havoc with airplane engines and must be avoided like the plague. Hawaii’s biggest island is effectively becoming a no-fly zone, because airlines don’t have enough reliable wind, weather, and ash data to safely operate in that airspace.

Spire Featured on Sky News

"Glasgow leads Britain's satellite space race" was the headline in a story that ran live on Sky News each hour on April 23rd. We had the unique opportunity to take Thomas Moore, Science Correspondent, through our Glasgow facility where we manufacture the satellites that provide our customers with data.
