项目摘要

The studies were performed for the 2 items using satellite data and ground data ; the distributions of air temperature and the distributions of wind speed.The distributions of air temperature in Liaoning Province, China were estimated using GMS data and the accuracy of air temperature were compared with our published data. The results are that the correlation coefficients between surface temperature derived from satellite and air temperature, and RMSE(Root Mean Square Error) are better at morning time and at night time than at day time. Especially, RMSE at 6-9 AM have the best.Also, air temperature and daily mean air temperature were estimated using surface temperature measured on the ground and these accuracy were compared with our published data. The results are that the correlation coefficients between surface temperature measured on the ground and daily mean air temperature, and RMSE are better at morning time(6 AM) and at evening time(6 PM).The measured wind speed in Toubetu and Shinsinotu, Hokkaido were compared with surface temperature derived from NOAA data. The result is that the correlation coefficients between surface temperature derived from satellite data and measured wind speed are better in May and June when measured wind speed are the strongest.

使用卫星数据和地面数据对这两个项目进行了研究；空气温度的分布和风速的分布。使用GMS数据估算了借用的空气温度的分布，并将空气温度的准确性与我们已发布的数据进行了比较。结果是，从卫星和空气温度得出的表面温度与RMSE（均方根误差）之间的相关系数在早晨和夜间比白天更好。尤其是，使用在地面上测得的表面温度估算的，在凌晨6-9时的RMSE估算了空气温度和每日平均空气温度，并将这些精度与我们已发布的数据进行了比较。结果表明，在早晨（上午6点）和晚上（下午6点）（下午6点）的地面温度与每日平均空气温度和每日的平均空气温度和RMSE之间的相关系数更好。与来自NOAA的表面温度衍生的Toubetu和Shinsinotu的测得的风速相比。结果是，在5月和6月测得的风速最强时，从卫星数据得出的表面温度和测得的风速之间的相关系数都更好。
