SELERYS engineers, deploys, and operates cloud seeding services and weather technology systems for partners who need more than an off-the-shelf solution.
Our cloud seeding services and full product range — the LAICO cloud seeding balloon and drone, the SKYDETECT radar, the EVEARLYS lightning detection system, and the CIRRUS weather management software — are backed by several patents and a team of more than 30 engineers and PhDs. Working across that many domains means SELERYS can take on custom projects other providers can’t. We put that same expertise to work for our clients.
SELERYS' cloud seeding services at a glance:
- Hardware engineering: custom meteorological equipment, designed and built in-house, from first specification to delivery
- Network deployment and operation: installation, monitoring, and maintenance for a weather sensor network, built on the same model Selerys uses for its own network worldwide
- Software and decision support: Selerys configures CIRRUS for a client's operation and can also take over day-to-day monitoring or automate decision-making entirely
- Program evaluation and validation: an independent, statistically grounded check on whether an existing cloud seeding or weather management program is delivering results
- Meteorological consultancy and training: risk assessment and hands-on training for hail mitigation, rain enhancement, snow enhancement, and fog dispersal
Hardware Engineering for Cloud Seeding
SELERYS built its radar, lightning detector, balloon-launch system, and cloud-seeding drone in-house. Owing to that experience, the same team develops custom meteorological equipment whenever a client’s needs fall outside the standard product line.
A typical custom build takes three to six months from specification to delivery, depending on complexity. Most requests come from a site condition or integration need the standard product line wasn’t built around — an unusual mounting environment, an existing sensor network the new equipment has to talk to, or a measurement Selerys’s current catalog doesn’t cover yet.
Custom Meteorological Equipment Essentials:
- A full written specification
- Manufacturing and testing under one roof
- CE certification, the same standard carried by Selerys’s off-the-shelf equipment
- A single point of contact from the first conversation through to completion
Network Deployment & Operation for SKYDETECT Radar
SELERYS installs a SKYDETECT radar unit in a single day, then keeps the network running by checking equipment health, resolving faults quickly, and training the client’s own staff toward full operational independence.
We give the client live monitoring and control of the network through CIRRUS, our weather management software, from any device, anywhere. Every piece of equipment Selerys installs worldwide is monitored around the clock through its own centralized IT infrastructure. If something goes wrong, SELERYS and the client are automatically notified day or night. Because of this centralized monitoring, SELERYS‘s engineering team can often diagnose and resolve issues remotely, regardless of the client’s location, without an on-site visit.
Weather Sensor Network Coverage:
- A site survey before installation, checking power supply, sightlines, and access
- Installation of a standalone SKYDETECT unit
- Live monitoring through CIRRUS, with the status of every sensor visible at any time, from any device
- Round-the-clock automated fault detection, with remote troubleshooting in most cases
- Training for on-site staff, building toward full independent operation
Software & Decision Support for Cloud Seeding and Storm Warning
SELERYS customizes CIRRUS software for each client’s operation. For larger deployments already running other sensors, CIRRUS can ingest that data directly, or SELERYS can build a custom connection to bring it into a separate display.
Beyond configuration, SELERYS offers two levels of hands-on support: taking over day-to-day monitoring and launch decisions on a client’s behalf, or automating the decision-making itself with SELERYS‘s own algorithms, an approach already running successfully for other clients.
CIRRUS Configuration Capabilities:
- Alerts by SMS, email, or phone, triggered whenever a weather threshold is crossed in a chosen zone
- Role-based access for field staff, control-room operators, and management
- Delegated operation, where SELERYS‘s own team handles day-to-day monitoring and launch decisions
- Automated decision-making, using Selerys’s own algorithms to set the rules for when and where to act
- Ongoing support beyond the initial setup
Program Evaluation & Validation for Cloud Seeding
A hail mitigation program implemented by SELERYS in a prestigious European wine-growing region demonstrated remarkable effectiveness: while hail increased by 222% in unprotected areas, our solutions reduced risk in the treated zone by 87%, meaning 7 times fewer impacts. For the most destructive hailstones (>2.5 cm), risk fell by 100%, with no damage recorded over 4 years.
Meanwhile, a rain enhancement program in Romania increased rainfall by >20%, as Romania’s Ministry of Agriculture independently confirmed.
The wine-region study used a spatio-temporal evaluation, comparing conditions before and after seeding with untreated reference zones; that study is currently undergoing peer review for scientific publication. The Romania result came from field measurement instead: rain gauges and radar tracked seeded zones against neighboring unseeded ones, event by event.
Both methods are now available as standalone cloud seeding services. SELERYS can apply whichever fits the program being evaluated, typically over multiple seasons, to check whether an existing cloud seeding or weather management program — run by SELERYS or another provider — is working and worth its cost.
Not to mention, SELERYS can also supply the instrumentation needed to gather the data, such as weather stations, radar, or hail sensors, for clients who don’t already have it.
Evaluation Methodology and Deliverables:
- A spatio-temporal or field-measurement comparison, chosen to fit the program being evaluated
- An independent check on whether the results are real or due to chance
- Instrumentation supply, for clients who don’t already have the equipment needed to measure results
- A written report for investors, regulators, or a client’s own management.
Meteorological Consultancy & Training
Risk assessment starts with a client’s situation, the local climate, and the specific crop, site, or infrastructure at risk. For programs that need it, SELERYS also studies storm patterns themselves, using radar and weather-model data to determine precise rules for when and where to seed.
Training runs one to two weeks on site, delivered directly by SELERYS‘s own engineering team, and can include specialized modules such as lightning detection — built, in particular, on a program originally developed for CNES, the French space agency.
Consultancy and Training Scope:
- Risk assessment for hail mitigation, rain enhancement, snow enhancement, and fog dispersal, built around a client’s specific situation
- Storm-pattern studies using radar and weather-model data to define precise rules for when and where to seed
- Program design grounded in proven field results
- On-site training for a client’s own team, covering daily operation, maintenance, and decision-making, with specialized modules available, such as lightning detection.

Frequently Asked Questions
What cloud seeding services does SELERYS offer beyond its products?
Beyond our cloud seeding hardware, we offer five services: 1) custom hardware engineering for meteorological equipment outside the standard product line, 2) deployment and day-to-day operation of weather sensor networks worldwide, 3) configuration, delegated operation, and automated decision support for the CIRRUS software platform, 4) independent evaluation of an existing program’s results, and 5) meteorological consulting and training.
Does SELERYS operate weather sensor networks for clients, or only sell the hardware?
SELERYS both operates its own weather sensor networks worldwide and offers the same installation, monitoring, and maintenance service to partners who want a network run for them rather than just supplied.
Can SELERYS build custom meteorological equipment, not just its standard products?
Yes. The same in-house engineering team behind SKYDETECT (X-Band radar), EVEARLYS (lightning detection system), and LAICO (smart cloud seeding balloon and drone) also builds custom equipment, from the first specification through to manufacturing.
Does SELERYS check whether an existing cloud seeding or storm-warning program is working, or only design new ones?
Yes, this is offered as a standalone service. SELERYS checks whether an existing cloud seeding or weather management program, run by SELERYS or another company, is producing real, cost-effective results, typically over multiple seasons. Depending on the program, SELERYS uses either a spatio-temporal comparison or direct field measurement and can supply the instrumentation needed if a client doesn’t already have it.
What does SELERYS's consulting and training cover?
Our consulting program covers risk assessment and program design for hail mitigation, rain enhancement, snow enhancement, and fog dispersal, as well as storm-pattern studies using radar and weather model data. Training covers system operation, maintenance, and day-to-day decisions for a client’s own team, with specialized modules available, such as lightning detection. Our results include an 87% risk reduction in severe hail frequency, as well as a 100% reduction for the most destructive hailstones (>2.5 cm) in an important wine-growing region in Europe.
