In this notebook we use the last 7d of active fires.

Where get data? You can ask a specific location in history with the links below: Last fires data Ask archives data

Download the last 7 days into a file

const r = await fetch('https://firms.modaps.eosdis.nasa.gov/data/active_fire/modis-c6.1/csv/MODIS_C6_1_Global_7d.csv')
const content = await r.text();
const json = csvJSON(content, ',');
// filter cols and convert CSV to JSON
_fs.writeFileSync(__dirname + '/modis-active-fire.json', JSON.stringify(filter(json, ["latitude", "longitude", "acq_date"])));
print("Done!");
