请求参数

参数名	含义	规则数据	是否必填	缺省值
productCode	产品类型，见产品类型代码表	string	是	/
meteCode	要素类型，见要素类型代码表	string	是	/

productCode产品类型代码表

代码	说明	使用说明
sev	3857可视化产品（返回png红黑图及json文件）	黑图配合json文件可求解出各像素点气象要素值，详见下方红黑图使用说明或咨询技术支持
mfv	墨卡托投影整图产品（返回webp彩图及json文件）	彩图可直接叠加地图进行显示（配色方案下载）

meteCode要素类型代码表

ste	回波强度，单位：dBZ
precipint	降水强度，单位：mm/h

返回参数

参数名	含义	规则数据
status	String	状态码，非0表示没有正常获取到数据
productCode	String	产品类型编码
meteCode	String	要素编码
timeRange	String[]	请求的数据时间范围，格式：“yyyyMMddHH”
urls	Object	时间序列对应的文件，每个时次包括一个webp/png文件和一个json文件

json文件参数说明

min	气象要素最小值
max	气象要素最大值
width	图片宽度
height	图片高度
lonmin	图片经度最小值
latmin	图片纬度最小值
lonmax	图片经度最大值
latmax	图片纬度最大值

红黑图使用说明
本接口sev、sevg产品以红黑图形式提供，其优点是数据量小，传输速度快、存储量低。png图片中的R通道值与气象要素值存在线性映射关系，利用气象要素的最大值和最小值，将气象要素的真值映射到通道值的0~255，气象要素的最小值和最大值可从对应的json文件中读取。
要将红黑图像素点的通道值换算为气象要素值，公式如下：
气象要素值=min+R通道值/255*(max-min)
