日本EKO MR-60(Net Radiometer)凈輻射表和MF-11(Net Pyradiameter)凈輻射表通過直接測量每日的長波輻射和短波輻射,并計算得到凈輻射量。用于大氣輻射(云層/水蒸氣和二氧化碳等發(fā)出的輻射)和地球與大氣之間的凈輻射交換的氣象觀測。凈總輻射(短波+長波)通常由4個凈輻射表或者單個凈輻射表(其探測器能響應(yīng)全波段)進行測量。地球長波輻射表使用一個半球朝上的探測器測量向下發(fā)射的長波輻射。凈長波輻射和地氣系統(tǒng)向下的發(fā)射輻射可由計算得到。在許氣象/光伏/園藝/農(nóng)業(yè)和工業(yè)等領(lǐng)域得到了廣泛的使用。
