The first Chinese dynamic environment satellites HY-2 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 scatterom-eter in the Amazon rainforest region by the global scientists showed the variance of scatterome-ter backscatter coefficient measurements was less than 0.15 dB with the season. According to this results,the analysis on HY-2 microwave scatterometer measurement data of the Amazon rainforest region in 2012-2013 have been finished ,the results showed that HY-2 satellite scatterometer measurement performance onboard in 2012-2013 is very stable,which is consis-tent with the international research results that seasonal variation characteristic of HY-2 scat-terometer measurements in the Amazon rainforest is less than 0.15 dB.
