Attribution comes before extrapolation.
The rainfall reading program examines intervention studies and the statistical choices behind enhancement estimates. It is a literature and methods program. There is no weatherhill rainfall installation or weather-control service.
The next quantities to define
- Keep the intervention mechanism and eligible weather regime explicit.
- Distinguish independent replication from a new estimator applied to the same trial.
- Retain the exact rainfall population and averaging rule behind each percentage.
- Inspect allocation, controls, spatial dependence and uncertainty before comparing estimates.
Rainfall reanalysis does not decide the first collector product. The immediate engineering question remains the measured D-versus-C optical effect in FogLab.
Research context
The July 2026 Oman reanalysis reports a 6.68% estimate with a 95% interval of 2.21–12.88%. RET’s April 2026 announcement offers a conditional 10% guarantee. The interval includes 10%; the two numbers need matching endpoints and conditions before comparison. Read the sources, definitions and limits of this comparison.
