如何从netcdf文件中的后续日期减去连续的每日数据？

import netCDF4 as nc
import numpy as np

# 读取netcdf文件
dataset = nc.Dataset('your_file.nc')

# 获取时间变量
time = dataset.variables['time']

# 获取日期范围
start_date = time[0]
end_date = time[-1]

# 获取每日数据
daily_data = dataset.variables['daily_data']

# 计算每日数据的总和
daily_sum = np.sum(daily_data, axis=0)

# 从后续日期中减去每日数据的总和
result = dataset.variables['subsequent_date'][:] - daily_sum

# 创建新的netcdf文件并保存结果
new_dataset = nc.Dataset('result.nc', 'w')
new_dataset.createDimension('time', None)
new_time = new_dataset.createVariable('time', 'f8', ('time',))
new_time[:] = result
new_dataset.close()
