python读取气象nc数据

import netCDF4 as nc

dataset = nc.Dataset('xxx.nc')  # 读取数据
print(dataset.variables.keys())  # 输出所有变量
lon = dataset.variables['longitude'][:].data  # 读取经度
lat = dataset.variables['latitude'][:].data  # 读取维度
time = dataset.variables['time']  # 读取时间
real_time = nc.num2date(time, time.units).data  # 转成时间格式
u10 = dataset.variables['u10'][:].data  # 读取u10风速
