Performance analysis of the HaiYang-2A satellite microwave scatterometer measurements based on tropical

Peng Hailong,Mu Bo,Lin Mingsen,Zhou Wu

Strategic Study of CAE 2014, Volume 16, Issue 6, Pages 33-38

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.

Plant Traits for Phytoremediation in the Tropics Article

Xiangting Cleo Chen, Liling Huang, Tze Hsien Agnes Chang, Bee Lian Ong, Say Leong Ong, Jiangyong Hu

Engineering 2019, Volume 5, Issue 5, Pages 841-848 doi: 10.1016/j.eng.2019.07.019

Abstract:

Water is a limited and valuable resource. Singapore has four national sources of water supply, one of which is natural precipitation. Pollutants collected in stormwater runoff are deposited into drainage systems and reservoirs. Major nutrient pollutants found in local stormwater runoff include nitrate and phosphate, which may cause eutrophication. Bioretention systems are efficient in removing these pollutants in the presence of plants. This paper discusses plant traits that can enhance the phytoremediation of nutrient pollutants in stormwater runoff for application in bioretention systems. The plant species studied showed variations in chlorophyll florescence, leaf greenness, biomass production, and nitrate and phosphate removal. In general, dry biomass was moderately correlated to nitrate and phosphate removal (r = 0.339–0.501). Root, leaf, and total dry biomass of the native tree species showed a moderate to strong correlation with nitrate removal (r = 0.811, 0.657, and 0.727, respectively). Leaf dry biomass of fastgrowing plants also showed a moderate to strong relationship with the removal of both pollutants (r = 0.707 and 0.609, respectively). Root dry biomass of slow-growing plants showed a strong relationship with phosphate removal (r = 0.707), but the correlation was weaker for nitrate removal (r = 0.557). These results are valuable for choosing plants for application in bioretention systems.
