无法使用新测试版CDS下载era5的数据

Question

我无法使用Python中的cdsapi代码从era5下载数据。

这可能是由于我的 cdsapi 更新不正确，但不确定。

我已经分享了我的代码和错误消息.....如果有人知道其更正，请指导。

import cdsapi

dataset = "reanalysis-era5-single-levels"
request = {
    'product_type': ['reanalysis'],
    'variable': ['10m_u_component_of_wind', '10m_v_component_of_wind'],
    'year': ['2024'],
    'month': ['05'],
    'day': ['01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12', '13', '14',       '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31'],
    'time': ['00:00', '01:00', '02:00', '03:00', '04:00', '05:00', '06:00', '07:00', '08:00',   '09:00', '10:00', '11:00', '12:00', '13:00', '14:00', '15:00', '16:00', '17:00', '18:00', '19:00',   '20:00', '21:00', '22:00', '23:00'],
    'data_format': 'netcdf',
    'download_format': 'unarchived',
    'area': [38, 61, 23, 81]
}

client = cdsapi.Client()
client.retrieve(dataset, request).download()

使用上面的代码，我收到以下错误消息。 在我看来，这可能是因为新的 cdsapi key 的语法问题

有同样的问题，我需要更新 .cdsapi 文件，因为 url 和密钥由于某种原因发生了更改。

https://cds.climate.copernicus.eu/how-to-api

目前它表示该文件应包含： 网址：https://cds.climate.copernicus.eu/api 密钥：db7a9f5c-2064-4a6e-9b4f-d220a04a128e
