A 12 year land surface dataset from ATSR-2 and AATSR

拟议的研究旨在编制1995-2007年期间地球陆地表面的新的卫星数据集。ATSR仪器系列是在英国设计的，在精度上比以前的仪器有了显著的进步。准确使用卫星数据的一个主要问题是，我们必须透过经常模糊的大气层进行观察。本研究将利用创新设计的仪器方法，以高精度估算下垫面反射率。还提供了对大气气溶胶的独立估计。这些数据将被处理，以给出植被吸收的光的全球估计，它们是光合作用的关键驱动力，也是全球碳循环的主要部分。新的数据集将为气候科学和土地覆盖变化领域的其他研究人员提供便利，允许通过NERC和欧洲航天局（ESA）充分利用英国的投资。

The proposed research aims to develop a new satellite dataset of the Earth's land surface for the period 1995-2007. The ATSR instrument series was designed in the UK, and offers a significant advance on previous instruments in accuracy. A major problem in using satellite data accurately is that we must look through an often hazy atmosphere. The research will use the innovative design of the instrument method to to estimate with high accuracy the underlying surface reflectance. An independent estimate of atmospheric aerosol is also provided. The data will be processed to give a global estimate of light absorbed by vegetation, they key driver for photosynthesis and a major part of the global carbon cycle. The new dataset will facilitate other researchers in the fields of climate science and land cover change, allowing full explotation of Uk investment through NERC and the European Space Agency (ESA).
