日本EKO MR-60凈全輻射傳感器/四分量輻射傳感器
日本EKO MR-60(Net Radiometer)凈輻射表和MF-11(Net Pyradiameter)凈輻射表通過(guò)直接測(cè)量每日的長(zhǎng)波輻射和短波輻射,并計(jì)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(cè)。凈總輻射(短波+長(zhǎng)波)通常由4個(gè)凈輻射表或者單個(gè)凈輻射表(其探測(cè)器能響應(yīng)全波段)進(jìn)行測(cè)量。地球長(zhǎng)波輻射表使用一個(gè)半球朝上的探測(cè)器測(cè)量向下發(fā)射的長(zhǎng)波輻射。凈長(zhǎng)波輻射和地氣系統(tǒng)向下的發(fā)射輻射可由計(jì)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。
