EAQI (European Environment Agency): combines PM2.5, PM10, nitrogen dioxide and ozone on a 0–100+ scale; low = clean air, high = polluted. Particulate matter in micrograms per cubic meter (μg/m³): PM 2.5 are fine particles that penetrate the lungs; PM 10 are coarse inhalable particles. WHO daily limits: PM 2.5 ≤ 15, PM 10 ≤ 45.

Aurora—Improbabile

Space weather (also known as space meteorology). Planetary K-index (Kp, 0–9 scale): measures geomagnetic disturbance. Low = stable shortwave propagation for amateur radio; high = storms affecting satellites and GPS. Solar flux (F10.7 cm, in SFU): Sun's brightness in radio waves — high means active Sun. Aurora borealis visible only at Kp ≥ 5, at high northern latitudes (Iceland, northern Norway, Alaska) or southern (Patagonia, Antarctica).

NOAA SWPC (Space Weather Prediction Center): official US center for space weather forecasting, part of NOAA, operating 24/7 since 1965. The only body issuing global alerts for power grids, satellites, GPS and amateur radio. Public domain (17 USC § 105). swpc.noaa.gov →

Magnitudo sulla scala Richter (logaritmica): ogni incremento di 1 punto moltiplica per ~32 l'energia rilasciata. Colori: verde (M < 5, raramente dannoso), giallo (5–5,9 moderato), arancione (6–6,9 forte), rosso (7+ maggiore, danni gravi). Profondità in chilometri — più è superficiale (fino a ~70 km), maggiore l'impatto in superficie. Fonte: USGS.

Natural events tracked by NASA in near real-time: wildfires, severe storms, volcanoes, floods, droughts, sea ice, landslides and more. The icon shows the type of phenomenon. Magnitude, when available, appears in the source's unit — e.g. area in acres for wildfires. Source: NASA EONET.

Sobre os links deste bloco: cada evento aponta para a fonte oficial registrada pela NASA. Alguns eventos aparecem SEM link porque a fonte é o IRWIN (Integrated Reporting of Wildland-Fire Information — sistema de incêndios florestais dos Estados Unidos restrito às agências, que exige login); não faria sentido enviar o leitor a uma tela de acesso fechado. Outras fontes trazem dados brutos, porém públicos: o JTWC (Joint Typhoon Warning Center — centro de alerta de tufões da Marinha dos EUA) publica boletins de texto com a posição, a intensidade e a trajetória prevista do ciclone, em formato técnico; o NATICE (National Ice Center — centro nacional de gelo dos EUA) publica uma planilha CSV com todos os icebergs rastreados — para achar um específico, procure a linha com o nome mostrado (por exemplo, D33D). Fontes como o Smithsonian GVP (Global Volcanism Program — programa de vulcanismo global) abrem uma página comum.
