在没有考虑高程数据的预处理方法得到的NOAA AVHRR资料中,每条扫描线数据中的51点经纬度定位信息常常有误差,尤其是在海拔较高、距卫星星下点较远的定位点,其定位信息与实际差别很大。针对这种情况,该文描述了一种引入高程数据并结合51点定位信息对2048个扫描点定位进行快速、简易的订正方法,可有效地修正AVHRR资料预处理未考虑高程信息引起的经纬度定位偏差,以便于对分辨率和定位精度要求不高的用户更好地使用AVHRR数据。

This paper presents a comprehensive observa-tion technique on derived aerosols data from mobile sun-photometer graph and Terra-Moderate Resolution Imaging Spectroradiometer (MODIS) observation. Research results suggest that after being treated by the variational technique with respect to sunphotometer observations, the Terra- MODIS remote sensing aerosol data are remarkably im-proved, thus for the first time revealing features of the influ-ence of aerosols and pollution emissions of Beijing and its adjoining areas (Hebei, Shandong, etc. provinces). The re-gional impact features of aerosols are related with the pe-ripheral U-shape topography of Beijing. Analyses with Hy-brid Single Particle Lagrangian Integrated Trajectory model (HYSPLIT-4) and meteorological data in the case studied confirm the pollutants diffusion process along the trajectory from the sources in the south-west region, and the regional aerosol impact features.

采用NOAA/AVHRR资料,利用水体与地物光谱特性的差异,结合通道2方案和通道2/通道1方案,对4月博斯腾湖水体进行判识,而利用通道2、通道2/通道1并结合通道4的方案判识了10月博斯腾湖水体,在此基础上利用线性混合模式对混合像元做了处理,定量估算了1990—1998年4月和10月博斯腾湖的面积,调研了9年来博斯腾湖面积变化情况,表明9年间博斯腾湖面积呈增加趋势。进一步采用主成分分析方法对博斯腾湖面积增大原因做了初步的气候分析,表明1988年以来博斯腾湖地区气温升高、蒸发量减少、降水有所增加,而人类活动用水和出流稳定并有减少是博斯腾湖面积增加的主要原因。而博斯腾湖及上游地区季节性积雪的特征,使冬季积雪水资源注入博斯腾湖,导致春季博斯腾湖面积较秋季大。

应用MODIS地表反照率产品MCD43C3,结合青藏高原自然带数据、积雪覆盖率和植被指数数据,采用一元线性回归方法分析了2000~2016年青藏高原地表反照率的分布及变化特征,结果表明:1)高原地表反照率空间分布差异大,整体上东南部低、西北部高,受地形和地表覆盖影响较大。2)高原地表反照率四季的空间分布变化明显,高海拔山脉和高寒灌丛草甸是高原地表反照率年内和年际变化的敏感地区。3)高原地表反照率年变化介于0.19~0.26,一定程度上表现为"双峰单谷"型,与地表覆盖类型的季节变化密切相关。4)高原地表反照率年际变化整体呈缓慢波动减小的趋势,平均变率约为-0.4×10-3 a-1,减小的区域约占高原总面积的66%,川西—藏东针叶林带的西南部地区减小得最快,减小速率超过1.0×10-2 a-1。5)高原地表反照率减小与冰川消融和积雪减少密切相关,高原植被覆盖改善也是一个重要因素。

Total ozone observations from the Total Ozone Unit （TOU） aboard the Chinese second generation polar orbiting mete- orological satellite, Fengyun-3/A （FY-3/A）, revealed that total column ozone over the Arctic declined rapidly from the beginning of March 2011. An extensive region of low column amount formed around mid March; monthly mean total column ozone in March 2011 was about 30% lower than the average observed during 1979-2010. Daily total column density of ozone near the center of low ozone area in mid March was less than 240 Dobson units, about half the total column ozone amount observed during the same period of the prior 10 years. We analyzed total column ozone data from different satellites during 1979-2011. Results show that the Arctic depletion of ozone in spring 2011 was initiated by the cold polar vortex in the lower stratosphere. The March mean total ozone over the Arctic has shown a decreasing trend over the past 32 years, and its variation is strongly correlated with the polar vortex. A similar low ozone process of spring 1997 was compared to that of 2011, but daily variations of total ozone in March over the Northern Hemisphere in 1997 and 2011 have different patterns.

无论从气象角度还是气候角度讲,对卫星云辐射测值进行反演判释研究,从而提取诸如云顶高度、云顶温度、云的放射率、云厚以及云的含水量等参数都十分必要。本文主要介绍用NOAA卫星红外和微波通道测值,按其辐射率差比方法,定量判释两层云高的初步数值试验结果。经与地面实况对照分析表明:适当选择两组探测通道组合可以遥感两层云高,但还不能判释出中云和低云并存时各自的高度。
