Experiments: measure the world the same way, every time
Experiments turn curiosity into numbers. You follow a repeatable method, so a reading taken in Dhaka can sit next to one taken in California and still mean the same thing.
Why the method matters
A single reading is a story. Thousands of readings, all taken the same way, are a dataset. Every experiment on Rainflower comes with a clear method so your numbers can be trusted and compared.
Your readings join an open, worldwide dataset that researchers and other students can use.
- Measure rainfall and other things around you with simple, low-cost tools.
- Report on a regular schedule; a daily reading takes about two minutes.
- Add photos as evidence, so others can check your work.
- Earn raindrops for steady, reliable reporting.
Current experiments
1 runningHelp build a community rainfall dataset. Each day, check your rain collector and record what you observe. Each week, confirm your setup and results.
Your daily readings automatically roll up into weekly totals, rainy/dry day counts, highest rainfall and averages. Accurate, honest observations — including "no rain" and "missed" days — matter just as much as big numbers.
