Utilizing MODIS Data to Retrieve the Visibility and Microphysical Properties of Fog Happens in the Northwest China

大雾区域地面能见度、垂直总水汽含量、雾滴有效半径等因子是对大雾进行有效监测的重要参数。

The visibility , effective radii and liquid water path ( LWP ) of fog are the fundamental parameters for fog monitoring .

由于发现地面能见度的变化与总辐射的变化非常一致，而地面能见度与大气气溶胶具有很好的相关性，初步认为大气气溶胶含量的变化是地面太阳辐射变化的主要原因。

For the high correlation between surface visual range and aerosol loading , the variation of aerosol loading is probably the main cause for the changes of surface solar radiation .

光学厚度与地面水平能见度不呈简单的对应关系。

There is no simple one-to-one correspondence between optical depth and surface horizontal visibility .

地面气溶胶（能见度和气溶胶类型）对天空背景Tb有明显的影响，必须加以订正。

The influence of aerosol ( visibilities and aerosol types ) above the ground on the sky Tb cannot be neglected , which must be corrected .

冷锋型地面风速与能见度的反相关性优于蒙古气旋型，且锋后气温下降较蒙古气旋型显著。

The anticorrelation between wind speed and visibility in cold-front sandstorm is higher than in Mongolia cyclone sandstorm ; and the post-frontal temperature in cold-front sandstorm decreased more apparently than in Mongolia cyclone sandstorm .
