Summary

Description
English: This figure shows the solar radiation spectrum for direct light at both the top of the Earth's atmosphere (represented by yellow area) and at sea level (red area). The sun produces light with a distribution similar to what would be expected from a 5778 K (5505 °C) blackbody, which is approximately the sun's surface temperature. As light passes through the atmosphere, some is absorbed by gases with specific absorption bands. Additional light is redistributed by Raleigh scattering, which is responsible for the atmosphere's blue color. These curves are based on the American Society for Testing and Materials (ASTM) Terrestrial Reference Spectra, which are standards adopted by the photovoltaics industry to ensure consistent test conditions and are similar to the light that could be expected in North America. Regions for ultraviolet, visible and infrared light are indicated.
Italiano: La figura mostra lo spettro della radiazione solare per illuminazione diretta sia all'inizio che alla fine del'atmosfera terrestra. Il sole produce una luce con una distribuzione simile a quella che ci si attenderebbe da un corpo nero a 5778 K (5505 °C), che è approssimativamente la temperatura superficiale del sole. Mano a mano che la luce passa attraverso l'atmosfera, parte della radiazione è assorbita dai gas in specifiche bande di assorbimento. Un contributo additivo è dovuto allo scattering Raleigh, che è responsabile per il colore blu dell'atmosfera. Le curve sono basate sugli spettri di riferimento dell'American Society for Testing and Materials (ASTM), che sono standard adottati dall'industria fotovoltaica per assicurare condizioni di prova consistenti e sono simili al tipo di radiazione che è possibile aspettarsi nell'America del nord. Sono indicate le regioni per l'ultravioletto, il visibile e la luce infrarossa.
Čeština: Tento obrázek ukazuje spektrum slunečního záření pro přímé světlo jednak na horní hranici zemské atmosféry (reprezentované žlutou oblastí), tak na hladině moře (červená oblast). Slunce produkuje světlo s distribucí podobnou tomu, co by se dalo očekávat od černého tělesa o teplotě 5778 K (5505 °C), což je přibližně povrchová teplota slunce. Jak světlo prochází atmosférou, část je absorbována plyny se specifickými absorpčními pásy. Další světlo je redistribuováno Rayleighovým rozptylem, který je zodpovědný za modrou barvu atmosféry. Tyto křivky jsou založeny na terestrickém referenčním spektru Americké společnosti pro testování a materiály (American Society for Testing and Materials, ASTM), což jsou standardy přijaté fotovoltaickým průmyslem, které zajišťují konzistentní zkušební podmínky a jsou podobné světlu, které lze očekávat v Severní Americe. Zobrazují se oblasti pro ultrafialové, viditelné a infračervené světlo.
