After establishing an ozone sounding site, check the availability of expendables and spare parts. Making a list of these items is recommendable. A large variety of spare parts is available from Vaisala.
The list of expendables includes at least:
- Radiosondes, interfaces
- Sounding accessories (for example, balloons)
- Ozone solution chemicals
- Syringes, needles
- Protective gloves
- Triple-distilled or ion-changed water
