## Useful for

- Compute a monthly climatology from an Xarray air-temperature dataset with a SQL GROUP BY query.
- Query ARCO-ERA5 weather data from a public GCS bucket with SQL, selecting only needed columns.
- Register an Xarray dataset in DuckDB or PostgreSQL via ADBC and join it with tabular data.

## Why it’s here

- Star-counter measurements on 2026-10-30 (UTC), 21:36–23:51: 143 → 149 stars (+6). This is the change over that interval.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
