汤加人民，加油。。。从天上观测核爆般火山喷发

#首先，导入对应包
import netCDF4
import numpy as np
import cv2
import os

#已经下载好的数据目录
path=r'E:/b/HI/15'

file=os.listdir(path)
for i in range(len(file)):
    nc=netCDF4.Dataset(path+'/'+file[i])
    data1 = nc.variables['albedo_01'][:]
    data2 = nc.variables['albedo_02'][:]
    data3 = nc.variables['albedo_03'][:]
    merge=cv2.merge([data1,data2,data3])
    merge = merge * 255
    merge=merge[1400:1800,1900:2300,:]#裁剪关键区域
    cv2.imwrite('E:/b/out/'+file[i]+'.png',merge)
