Frequently Asked Questions

What is a Remote Automated Weather Station (RAWS)?

A Remote Automated Weather Station, or RAWS, is a field-deployed monitoring system that collects weather and environmental data with minimal on-site staffing. Typical systems measure conditions such as wind, precipitation, visibility, temperature, humidity, and atmospheric behavior, then transmit data to operators. OSI supports RAWS-style deployments through sensor selection, integration, communications design, commissioning, and long-term technical support.

What types of sensors can OSI integrate into RAWS systems?

Can RAWS systems operate in remote locations without grid power?

Does OSI provide installation and commissioning support?

How much maintenance do OSI weather monitoring systems require?

Do you provide training for RAWS operators and maintenance teams?

Can OSI upgrade or integrate with existing weather station infrastructure?

How are repairs and RMAs handled for OSI equipment?
