dc.description.abstractSimultaneous observations of net radiation and temperature for the entire partial eclipse were obtained at a site with maximum obscuration of 92% of the direct solar radiation. A strongly negative net radiation of −96 mly/min comparable to nocturnal conditions (−110 mly/min) was found at minimum light. Since lowlight levels under normal daytime conditions (thick clouds) coincide with weak temperature gradients, organisms with both optical and thermal sensors may show a confused behavior under eclipse conditions. The contribution of direct solar radiation to the net radiation was computed using limb-darkened solar eclipse functions (included in an appendix) which show considerable departures from the uniform disk approximation. Gleichzeitige Beobachtungen der Strahlungsbilanz und der Temperatur wurden für die Dauer der partiellen Phase der Sonnenfinsternis an einem Beobachtungsort angestellt, an dem zur Zeit der maximalen Finsternis 92% der direkten Sonnenstrahlung ausfielen. Eine stark negative Strahlungsbilanz von −96 mly/min, die nächtlichen Bedingungen (−110 mly/min) entspricht, wurde zum Zeitpunkt minimaler Einstrahlung vorgefunden. Da niedrige Lichtwerte unter normalen Tageslichtbedingungen (bei dichter Bewölkung) mit schwachen Temperaturgradienten zusammenfallen, können Organismen mit optischen und thermichen Sensoren unter den Bedingungen einer Sonnenfinsternis unregelmäßig reagieren. Der Beitrag der direkten Sonnenstrahlung zur Strahlungsbilanz wude mittels einer im Anhang angeführten Funktion berechnet, welche auf der Randverdunkelung der Sonne beruht. Diese Funktion zeigt bedeutsame Abweichungen gegenüber der Annahme einer gleichmäßigen Sonnenscheibe.en_US
