Tomorrow.io unveils DeepSky satellite network for severe storms

Tomorrow.io introduced the DeepSky constellation payload architecture in Boston on September 10, 2026, targeting emergency weather notifications for more than 5 billion people currently living outside terrestrial radar range.

The space platform integrates five separate observation payloads to eliminate worldwide gaps in meteorological tracking. Instruments on board include spaceborne precipitation radar, microwave hyperspectral sounders, optical and infrared imagers, GNSS radio occultation receivers, and GNSS reflectometry tools.

Oceans cover roughly 71% of Earth without fixed weather stations, allowing oceanic tempests to form unseen before hitting shipping lanes and coastal communities.

“Those with the least lead time have the most to lose,” said Tomorrow.io chief executive officer and co-founder Shimon Elkabetz. Shimon Elkabetz stated that open-ocean storms receive significantly less attention than events striking affluent coastlines, causing preventable casualties that the spaceborne mission intends to mitigate by supplying early atmospheric observations directly to emergency decision-makers.

The DeepSky architecture augments the operational Sky 1 numerical model, which generates global weather projections every hour.

Satellite architecture housing multiple monitoring sensors

Engineers designed each satellite chassis with larger dimensions than standard orbital sounders to consolidate the full scientific payload on one bus. This unified structure enables all five instruments to sample the identical atmospheric column at the exact same moment.

• Spaceborne precipitation radar: maps three-dimensional storm structures and measures the location of heavy rainfall and vertical drafts.
• Microwave hyperspectral sounders: detect vertical shifts in atmospheric temperature and moisture beneath cloud layers throughout day and night.
• Optical and infrared imagers: document storm-top temperatures and cloud geometries during orbital passes while identifying active wildfires.
• GNSS radio occultation: provides vertically resolved refractivity benchmarks linked to onboard atomic timekeeping to calibrate the orbital network.
• GNSS reflectometry: measures ocean surface wind speeds inside intense storm cores where conventional radars lose signal penetration.

Atmospheric data synthesis and international applications

Synchronized active and passive sensors in low Earth orbit stream verified measurements that feed artificial intelligence models.

“A forecast can only be as good as what was actually measured,” said Tomorrow.io chief strategy officer and co-founder Rei Goffer. Rei Goffer explained that observational gaps previously forced legacy numerical models to substitute real atmospheric measurements with mathematical approximations.

The orbital feeds support public hydrological agencies alongside commercial aviation, agriculture, maritime logistics, and power utility operators trying to anticipate storm impacts.

Tomorrow.io already operates 11 first-generation atmospheric sounders in low Earth orbit that stream data into Sky 1. Production is underway.

The company maintains its global corporate headquarters in Boston and delivers environmental intelligence to civil authorities and multinational enterprises.
