Step 1
Collect everything in the field
- 1-minute observation at each site
- Link and device status logged
- Gaps flagged

Field Rainfall Data API
Summary
Neighborhood-level field rainfall every minute, with quality information, ready to use.
KEY POINTS
- 1 MIN
Minute-level field rainfall
Rainfall, wind direction and speed every minute at each site
- QC
Quality built in
Raw/corrected status and quality flags with every value
- DENSE
Neighborhood density
Observation points at neighborhood, not district, level
- REST
Standard REST · JSON
Query APIs plus threshold webhooks
One request, ready-to-use data
Query the latest values by observation point ID.

}What’s different
| WOOZZA Field Rainfall API | Typical open weather data | |
|---|---|---|
| Density | Neighborhood-level points | District- or regional-level stations |
| Update | Every minute | Varies by dataset and provider |
| Quality info | Raw/corrected status + quality flags | Mostly values only |
| Query by | Observation point · 1 km grid | Station |
| Alerts | Threshold webhooks | Build it yourself |
