摘要
介绍了新一代天气雷达产品的文件数据格式及实现在MICAPS中显示的方法。给出了在Lambert投影下将雷达回波的极坐标数据转换成经纬度位置 ,并计算网格点坐标的公式。通过更换BMP图像文件的文件头 ,实现MICAPS十三类数据格式的转换。并对坐标缩放系数的计算、调色板文件进行了说明。
The data file and the displaying method of the CINRAD′s products in MICAPS are introduced. In order to convert the radar echo data in polar coordinate into the data in grid coordinate, the formulas for calculating geographical position in Lambert projection are given. The 13th data file of MICAPS is obtained through changing the head of BMP picture file. The calculating method of the zoom coefficient in different coordinate and the color map file are introduced too.
