5. The State of Weather Satellites and Why They Barely Get Any Attention

The news that the US Space Force (USSF), for the second time, has taken ownership of a retired NOAA weather satellite to fill gaps in coverage for the U.S. military should have been a shock for many in the industry. If you are wondering why the USSF had to rely on a decade-old satellite, it is because that is all they can do at this moment to acquire weather data.

The USSF has its own weather programme called the Defense Meteorological Satellite Program, but the decades-old satellites are running out of fuel and are projected to be out of service before 2026. The USSF is currently evaluating concepts for a follow-up programme, called, Electro-Optical/Infrared (EO/IR) Weather Systems, with a couple of demonstrators already launched.

You might ask, but how did we get here? How has there not been a trend similar to the imaging business, in which the private sector has won billion-dollar contracts to supply satellite imagery to the US DoD? Where are the companies supplying weather data?

The following figure, from a Spire presentation, is a tad outdated - today, there are a handful of weather satellite companies, but the message it sends is not entirely wrong. The number is nowhere near the number of EO imaging satellite companies.

The Space Force believes that the available offering from the private sector doesn’t fill their needs just yet, and hence, they announced that they will not resort to a model akin to the data buy approach in the imaging business anytime soon. NOAA, the civilian weather agency, on the other hand, believes that “it expected more satellite companies to enter the market, but they have been slow to emerge.”

It might seem like the commercial space industry has effectively ‘failed’ in delivering to the needs of NOAA and the US DoD, with respect to the acquisition of satellite data for weather forecasting. But, there are two important reasons why I think this is the case:

  1. A lack of understanding of weather from space

I cannot overemphasise this, very few industry professionals and investors actually even properly understand the weather segment. Based on my experiences, not many have insights into the gaps in weather forecasting and climate modelling, the technologies we need to fill those gaps and the challenges of the private weather enterprise.

Weather has been in the realm of governmental agencies, owning the gap analysis, missions and roadmaps, with the private sector mostly just executing. Just like in the early days of EO imaging, weather was restricted to the scientific community. Some of us may have even assumed we are doing alright with the collection of weather data, and the space agencies are taking care of everything - but no, there are plenty of gaps. I believe these gaps will increasingly come to the forefront, as the effects of climate change take centre stage globally.

Not many weather satellite companies here
  1. The tricky business case for weather from space

Only a handful of weather agencies globally are in a position to buy spaceborne weather data, because they are the only ones who know what to do with it2. So, the private sector is forced to employ a "build it, they will come" approach. And, that is not a good business case to start a company. Also, agencies just don't sign large-sized contracts once data is available, they do many smaller contracts to evaluate the quality of data (and rightly so). Meaning, there is a severe lack of incentives for companies to create business plans to build and launch satellites.

Companies are expected to go all-in and vertically integrate altogether - they need to sell weather data to agencies (DaaS model), but also build enterprise software to sell weather insights to companies across sectors (SaaS model). However, this full-scale vertical integration is tough and expensive to pull off, so very few companies even attempt to enter the satellite weather market.

Therefore, it is no surprise that the list of companies building and launching weather satellites as a business is a pretty short list - Tomorrow.io, Spire, GeoOptics, PlanetIQ, Orbital Micro Systems, MyRadar, Care Weather.

Weather is an incredibly complex business to understand

We have a lot of work to do, both in communicating about the importance of weather from space, understanding the gaps in weather data around the world as well as figuring out the business models for satellite-based weather data. After all, the planet is not getting any cooler.

6. Breathing Toxic Air in Europe

An investigation by The Guardian has found that about 98% of Europeans are breathing highly damaging polluted air, linked to 400,000 deaths a year, with only 2% of the population in the continent living in areas within this limit. The figure below shows the PM 2.5 levels across Europe the results of the analysis, were conducted using data from a combination of sources - from high-resolution satellite data to pollution monitoring stations and information about land use.

Particulate Matter (PM) 2.5 refers to the concentration of tiny airborne particles, mostly produced from the burning of fossil fuels, which can pass through the lungs and into the bloodstream, affecting almost every organ in the body. Looks like it might be a good time to take action on air pollution now!

  1. A floodplain is an area bordering a river that naturally provides space for the retention of flood and rainwater. With the loss of floodplains, the size of the country of Madagascar, it should come as no surprise that flood risks are increasing.

  2. There is an added complication due to the open data sharing policy, which might seem ethically right for weather data, but might not be the best thing for running a business. More on that in my deep dive!
