Abstract
The first Chinese dynamic environment satellites HaiYang-2A(HY-2A) satellite was successfully launched on August 16, 2011, with a Ku-band microwave scatterometer which can provide wind vector information of global ocean surface. The research results for all launched scatterometer in the Amazon rainforest region by the global scientists showed the variance of scatterometer backscatter coefficient measurements was less than 0.15dB with the season. According to this results, the analysis on HY-2A microwave scatterometer measurement data of the Amazon rainforest region in 2012—2013 have been finished, the results showed that HY-2A satellite scatterometer measurement performance onboard in 2012-2013 is very stable, which is consistent with the international research results that seasonal variation characteristic of HY-2A scatterometer measurements in the Amazon rainforest is less than 0.15dB.
