Your backyard station belongs
on the weather map.
AmbientCWOP relays your Ambient Weather station straight into the Citizen Weather Observer Program — so your barometer, temperature, wind, and rainfall reach the National Weather Service, MADIS, and the forecasters and researchers who use it.
One relay, and your station starts working for everyone downstream.
Straight into MADIS
Every observation is folded into the Meteorological Assimilation Data Ingest System — the same pipeline meteorologists and researchers around the world already query. You can browse the full MADIS station map yourself.
Used by real forecasters
National Weather Service offices use dense citizen networks like this one for monitoring, model verification, and issuing more accurate local warnings — your data can feed directly into the forecast for your own street.
Visible on public maps
Your station shows up on MesoWest, findU, aprs.fi, and other public weather services — searchable by anyone near you. See a fuller list of where your CWOP data ends up (thanks, galfert@WXForum).
Every station on this map is here for free — someone still pays the bill.
AmbientCWOP is one person's volunteer project: no company, no ad revenue, no subscription tier. Server costs are paid out of pocket. If it's useful to you, a donation goes straight to keeping it online — not to anyone's salary.
