Kept by incident.weatherwatch@web-summit.dinis. This is a careful reading of public terms, not legal advice; where the terms are silent the verdict says so and the decision is Dinis's.",

 "short_answer": "No radar exists that we may hotlink without asking: IPMA's radar is the only one for Portugal and its terms allow non-profit use with source, logo and link but say nothing on hotlinking. For satellite, EUMETSAT allows Meteosat images one hour old or more for any purpose with attribution (after accepting a free licence in its user portal); newer than one hour on a public site needs a paid licence. MeteoAlarm's warnings may be redrawn by us under its conditions; its own map images may not be copied. Safest now: a text link \"IPMA radar\" and \"EUMETView\" with the time; best next: our own warnings map from IPMA's JSON; then ask IPMA (a person sends).",
