The difference between the amount of energy the Earth receives from the sun and the energy it radiates back to space affects whether our planet's climate warms or cools. For now, nobody can measure that temperature difference precisely, but scientists at Johns Hopkins University’s Applied Physics Laboratory, in Maryland, plan to change that, using an array of small, inexpensive satellites called ‘cubesats.’ VOA’s George Putic has more.
地球從太陽上接收能量的數量與地球向太空中反射能量數量之間存在差異,這一差異可以反映地球氣候冷暖如何 。如今,沒人能夠精測測量這一溫差,但是,在坐落于馬里蘭的美國約翰霍普金斯大學應用物理實驗室中,科學家們計劃改變這一狀況,方法就是使用一些小型、價格不貴的衛星,他們稱其為“cubesats”本臺記者喬治·卜迪科為我們帶來更多報道 。
