对于研究全球变暖现象的科学家来说,一定面积内的生物量,即有生命的物质总量,例如植被,是重要的信息。生长中的森林从大气中吸收碳,因此能减缓变暖现象,而砍伐森林则会把碳放回到空气中。一种最新的遥感仪器现在已能以前所未有的精度和覆盖范围向研究人员提供有关生物量的信息。 For scientists studying the phenomenon of global warming, biomass within a certain area, ie, the total amount of living material, such as vegetation, is an important message. Growing forests absorb carbon from the atmosphere, thus slowing the warming process, while deforestation puts carbon back into the air. A state-of-the-art remote sensing instrument now provides researchers with information about biomass with unprecedented accuracy and coverage.
