ASOTELE / A PUBLIC FORECAST LEDGER

Forecasts, filed before the fact

Every week this repository commits probabilistic forecasts of verifiable public quantities, then scores them against what actually happened, by a proper scoring rule, forever. Nothing is deleted and nothing can be: the git history is the notary.

No forecast has matured yet. The first scores appear automatically once the first target week ends and its revision window passes. Until then, the only honest scoreboard is an empty one.

The rules, fixed in advance. Forecasts are 23 quantiles, committed before the target week begins (the commit timestamp on each linked file is the proof). Outcomes are decided by resolution procedures written per target in targets.py, after a waiting period that lets source revisions settle. Scoring is the weighted interval score, a proper rule: the expected score is minimised by honest forecasts, so the only way to look good on this page is to be right. A bad week stays on the ledger with the same weight as a good one.

What is being forecast

Earthquakes of magnitude 4.5 or greater, worldwide (count in the target week). USGS fdsnws event count, minmagnitude=4.5, over the target week in UTC, queried no earlier than 7 days after the week ends. The catalogue is revised for a few days after an event; the 7-day wait lets magnitudes settle, and whatever the API returns at scoring time is final for the ledger.

Warmest daily maximum in Central Park, New York (degrees C over the target week). Open-Meteo archive API, daily temperature_2m_max at 40.7789N 73.9692W, maximum over the 7 local days of the target week, queried no earlier than 7 days after the week ends.

Warmest daily maximum at Seattle-Tacoma (degrees C over the target week). Open-Meteo archive API, daily temperature_2m_max at 47.4444N 122.3139W, maximum over the 7 local days of the target week, queried no earlier than 7 days after the week ends.
