Weather balloons are used for atmospheric probing by the Institute of Meteorology and Water Management (IMWM). Every day in three centers – Łeba, Legionowo, Wrocław – IMWM employees send probes to perform measurements that are used to determine the weather conditions for Poland.

The same type of balloons is used to carry out amateur stratospheric missions. Every year there are many student groups associated with scientific circles or simply informal groups, such as Copernicus Project organizes flights deep into the stratosphere.

The individual types of meteorological balloons are usually encoded in the name itself, which have their own weight, which determines their technical capabilities.

For our and your convenience, we have distinguished 3 groups of balloons:
1. small -> 100g, 200g, 350g
2. medium -> 500g/600g, 800g/875g, 1000g,
3. large -> 1200g, 1500g/1600g, 2000g, 3000g, 4000g

Summary and specifications with technical parameters are available in our brochure – recommended weather balloons (PDF).

So if you choose the CPR-1000 coating, you already know that it weighs 1000g.
We use this data to prepare a flight strategy. On its basis, we can determine the required amount of gas and the possible weight of the capsule itself.

Weather balloons small They can be used for technical equipment tests, i.e. test flights or sending very light loads, e.g. the Vaisala RS41 radio probe.

Weather balloons medium are used to implement the first ambitious missions. The recommended weight of the load is about 250 g.

Weather balloons large are the ones that allow you to lift loads weighing more than 1000g. This gives us the greatest opportunities to experiment.
