【摘要】：利用美国国家浮标数据中心NDBC和热带大气海洋计划TAO浮标的海表面温度数据,对Wind Sat 2004年—2013年近10年的海表面温度产品进行了验证。结果表明,在美国沿岸海域,Wind Sat反演得到的海表面温度的平均偏差为0.10°C,标准偏差为0.59°C;在近赤道太平洋海域,反演得到的海表面温度的平均偏差为 0.15°C,标准偏差为0.33°C。Wind Sat海表面温度在夏季相对浮标实测值有正偏差增大和负偏差缩小的趋势,在美国东海岸以及墨西哥湾区域部分站点反演得到的海表面温度的标准偏差较大,其标准偏差超过1°C。在5 10 m/s风速段,Wind Sat海表面温度反演效果比较理想,平均偏差和标准偏差相对恒定。当风速大于12 m/s时,Wind Sat海表面温度反演的不确定性明显增加。与AMSR-E月平均海表面温度产品对比发现,夏季,Wind Sat SST较AMSRE偏低;冬季,Wind Sat SST较AMSR-E偏高。
[Abstract]:Based on the sea surface temperature data of the National buoy data Center (NDBC) and the Tropical Atmospheric Oceanic Program (TAO) buoy, the products of Wind Sat from 2004 to 2013 for nearly 10 years were verified. The results show that the average deviation of sea surface temperature is 0.10 掳C and the standard deviation is 0.59 掳C in the coastal waters of the United States by Wind Sat inversion, while in the near equatorial Pacific Ocean, the mean deviation is 0.10 掳C and the standard deviation is 0.59 掳C. The average deviation of sea surface temperature is 0. 15 掳C, and the standard deviation is 0. 33 掳C.Wind Sat. The standard deviation of sea surface temperature obtained from the inversion of some stations on the eastern coast of the United States and the Gulf of Mexico region is larger than 1 掳C. In the wind speed range of 5 ~ 10 m / s, the inversion effect of sea surface temperature in Wind Sat is relatively ideal, and the average deviation and standard deviation are relatively constant. When the wind speed is greater than 12 m / s, the uncertainty of sea surface temperature inversion in Wind Sat is obviously increased. Comparing with the AMSR-E monthly mean sea surface temperature products, it is found that the Sat SST of Wind in summer is lower than that of AMSRE, and the Sat SST of Wind in winter is higher than that of AMSR-E.
