Use the API

Each series and location is its own small file. The examples follow the series and location picked above. See the docs for versions, caching and errors.

# One series for one place (.json or .csv)
curl -s "https://api.climatedata.dev/v1/greenhouse-gases/ch4/world.json"

# Every series and place in one file
curl -sO "https://api.climatedata.dev/v1/greenhouse-gases/download/greenhouse-gases.csv"

import polars as pl

# One series for one place
df = pl.read_csv("https://api.climatedata.dev/v1/greenhouse-gases/ch4/world.csv")

# Every series and place, with series and location columns
everything = pl.read_parquet("https://api.climatedata.dev/v1/greenhouse-gases/download/greenhouse-gases.parquet")

const res = await fetch("https://api.climatedata.dev/v1/greenhouse-gases/ch4/world.json");
if (!res.ok) throw new Error((await res.json()).detail); // errors are problem+json
const { meta, data } = await res.json();
console.log(meta.location_name, data.at(-1)); // { date, value, ... }

Downloads

Schema and series

Each series file has these columns. The bulk downloads add series and location columns in front.
