Frequently Asked Questions
No, it is a very low-frequency technical term used almost exclusively in meteorology and related fields.
A rawin uses radar to track a balloon to measure wind. A radiosonde is a balloon-borne instrument package that measures temperature, humidity, and pressure, and often wind via radio tracking (then called a rawinsonde).
No, it is not standard to use 'rawin' as a verb. It is a noun, typically used attributively (e.g., rawin data).
No. It is a highly specialised term. Learners should be aware of its existence in a technical context but do not need to actively learn it for general proficiency.
