【摘要】：選用浮標、志愿觀測船舶(VOS)數(shù)據(jù)作為驗證數(shù)據(jù)對MODIS Aqua,MODIS Terra,AVHRR-OI,OSTIA和RTG五種SST日產(chǎn)品進行了時相差異、近海SST偏差和SST偏差區(qū)域整體差異分析的質(zhì)量評價,以期為日產(chǎn)品的后續(xù)應用提供依據(jù)。結(jié)果表明:不同分析方案得到結(jié)論基本一致,在時相差異方面,各季節(jié)及年度分析顯示各日產(chǎn)品優(yōu)劣特性相近,其中AVHRR-OI最優(yōu)(年數(shù)據(jù)分析回歸系數(shù)為0.973 6,R2為0.976 0,RMSE為0.71℃),RTG、MODIS Aqua和MODIS Terra次之,OSTIA最差(年數(shù)據(jù)分析回歸系數(shù)為0.945 4,R2為0.943 7,RMSE為1.08℃);在近海區(qū)域,AVHRR-OI比其他日產(chǎn)品能更真實地反映海表溫度狀況,OSTIA最差(二者Grade分別為30和13);在海洋表面區(qū)域整體特性方面,AVHRR-OI日產(chǎn)品質(zhì)量在研究區(qū)海域存在更少的高正值和低負值,且均值和RMSE也更理想(最低僅分別為0.40和0.59℃);而RTG和OSTIA則差于AVHRR-OI。
[Abstract]:Using buoy, (VOS) data of voluntary observation ship as the verification data, the quality evaluation of MODIS Aqua,MODIS Terra,AVHRR-OI,OSTIA and RTG five kinds of SST daily products are carried out, and the overall difference analysis between offshore SST deviation and SST deviation area is made. In order to provide the basis for the follow-up application of Japanese products. The results show that the conclusions of different analysis schemes are basically the same. In terms of time phase difference, each season and year analysis show that the advantages and disadvantages of each day's products are similar, among which AVHRR-OI is the best (the regression coefficient of annual data analysis is 0.973, and the annual data analysis regression coefficient is 0.973). R2 was 0.976 鈩，
