How mobile phone towers could help monitor rainfall in developing countries
- The conversation
- Many developing economies suffer from a lack of reliable rainfall measurements due to a lack of funds and a shortage of equipment – such as gauges and radars. Even if countries are equipped with these monitoring instruments, they all have limitations. Rain gauges, meteorological instruments that collect falling water drops, only provide a very local observation. However, the intensity of rainfall can be completely different from one location to another, sometimes even if it's less than a few hundreds of metres away. Radars use radio waves to get precipitation estimates but they may not always be efficient. For example, their beams might get blocked in mountainous regions.
