网页上只能下载hourly数据吗？想要月平均的数据，但是每次一提交脚本就是在排队，下不下来

# Import cdsapi and create a Client instance
import cdsapi
c = cdsapi.Client()
# More complex request
c.retrieve("reanalysis-era5-pressure-levels", {
        "product_type":   "reanalysis",
        "format":         "netcdf",
        "area":           "52.00/2.00/40.00/20.00",
        "variable":       ["geopotential","temperature"],
        "pressure_level": ["700","900"],

    }, "output.nc")

我是这样弄得
