1·Do not include the radar base reflectivity image as it can make precise area location more difficult.
请勿包括雷达基本反射率图像，因为它可能会使精确定位地区变得更困难。
2·With these layers downloaded, you can combine them with the base reflectivity image to produce a more easily readable image map.
下载了这些图层之后，您可以把它们与基本反射率图像结合起来生成更易于阅读的图像地图。
3·First, scan the reflectivity data in the immediate area around the detection coordinates, allowing for precipitation front movement from any direction.
首先，扫描检测坐标周围紧接区域中的反射率数据，允许降水前锋移向任意方向。
4·With your selected pixel coordinates and a single-layer base reflectivity map, the logical process for detecting precipitation near a spot on the map is straightforward.
使用选定的像素坐标和单层基本反射率图，检测地图中某个场所附近的降水的逻辑过程将十分简单。
5·Figure 3 shows a sample base reflectivity image on a clear day in central North Carolina.
图3显示了北卡罗来纳州中部晴天的基本反射率图像样例。
