【wrf-python】批量读取多个nc文件中共同的变量并保存为csv文件

2023-12-24 21:33:38
import xarray 
import os

path = "/copy_merge/"
comb_ds = xr.Dataset()
for root, dirs, files in os.walk(path):
    for file in files:
        if file.endswith(".nc"):
            ds = xr.open_dataset(os.path.join(root, file))
            tSK_var = ds['TSK']
            comb_ds[file] = tSK_var
comb_ds.to_netcdf("combined_data1.nc")


path = "combined_data1.nc"
ds= xr.open_dataset(path)

df=ds.to_dataframe()
df
df.to_csv("output1.csv")

对经纬度范围和时间进行切片保存

import xarray as xr
import os


path = "/copy_merge/"

#创建空的dataset
comb_ds = xr.Dataset()

#遍历路径中的nc文件，并提取变量
for root, dirs, files in os.walk(path):
    for file in files:
        if file.endswith(".nc"):
            ds = xr.open_dataset(os.path.join(root, file))
            rain = ds['RAINNC'][1:,::]
            
            comb_ds[file] = rain
        print(comb_ds)
comb_ds.to_netcdf("combined_data1.nc")

path = "combined_data1.nc"
ds = xr.open_dataset(path)
ds1=ds.sel(south_north=slice(9,108), west_east=slice(9,88))
ds1.to_netcdf("wuwei_RAINNC.nc")
df = xr.open_dataset("wuwei_RAINNC.nc")
df1=df.to_dataframe()
df1.to_csv("RAINNC.csv")
