Where this comes from

Derived, not researched: models in the directory whose class matches a class this use case uses, excluding family records and models shut down or deprecated. Ranked by how many fit facts they meet, then by release date. Each fit fact is read from the model record.

Use Case

Industry: agriculture and plantations
Model classes: weather
Benchmarks or datasets: not in the notes
Regulatory notes: Surat Edaran Menkominfo 9/2023 Etika Kecerdasan Artifisial, Kementerian Komunikasi dan Informatika (now Kementerian Komunikasi dan Digital)Weather forecasting is an AI-based service run by an electronic system operator, and the circular asks such operators to build and use AI on the values of inclusivity, transparency, humanity and security.
UU 31/2009 Meteorologi, Klimatologi, dan Geofisika, DPR and President of the Republic of Indonesia (BMKG)Weather forecasting produces weather forecasts, an area where this law makes BMKG the official source of public meteorological information and warnings.

Where this comes from

From the industry tracks T08 to T10 of the research notes.
