前言
在当今数据驱动的世界中，气象数据对于众多领域如农业、能源、交通、环境科学等都至关重要。无论是进行科学研究还是商业决策，准确且易于获取的气象数据都是不可或缺的。然而，收集和处理这些数据往往是一个复杂且耗时的过程。幸运的是，Python 社区提供了许多强大的工具来简化这一过程，其中 meteostat 库就是一个非常实用的选择。
meteostat 是一个开源的 Python 库，旨在提供简单而高效的接口来访问历史和实时气象数据。它支持全球数以万计的气象站，包括月度、每日和每小时的数据记录。通过 meteostat，开发者和研究人员可以轻松地下载所需的数据，无需担心复杂的 API 调用或数据格式转换问题。
数据源包括国家气象局，如美国国家海洋和大气管理局 （NOAA） 和德国国家气象局 （DWD）。
本文将详细介绍如何使用 meteostat 库来下载气象站点的月度、每日和每小时数据，并展示一些实际应用案例。无论你是初学者还是有经验的开发者，都能从本文中获得有价值的信息，从而更高效地利用气象数据进行分析和研究。
安装库
!pip install meteostat -i https://pypi.mirrors.ustc.edu.cn/simple/

下面我们查询一下该库能访问的天津的气象站数量
from meteostat import Stations
stations = Stations()
stations = stations.region('CN','TJ')
print('Stations in Ontario:', stations.count())
Stations in Ontario: 2根据经纬度查询临近站点信息
# Import Meteostat library
from meteostat import Stations
# Get nearby weather stations
stations = Stations()
stations = stations.nearby(39, 118)
station = stations.fetch(1)
# Print DataFrame
print(station)

下载月数据
# Import Meteostat library and dependencies
from datetime import datetime
import matplotlib.pyplot as plt
from meteostat import Stations, Monthly
# Set time period
start = datetime(2000, 1, 1)
end = datetime(2018, 12, 31)
# Get Monthly data
data = Monthly('ZBTJ0', start, end)
data = data.fetch()
# Plot line chart including average, minimum and maximum temperature
data.plot(y=['tavg', 'tmin', 'tmax'])
plt.show()
UserWarning: Could not infer format, so each element will be parsed individually, falling back to `dateutil`. To ensure parsing is consistent and as-expected, please specify a format.
下载日数据
# Import Meteostat library and dependencies
from datetime import datetime
import matplotlib.pyplot as plt
from meteostat import Point, Daily
# Set time period
start = datetime(2022, 1, 1)
end = datetime(2022, 12, 31)
# Create Point for Vancouver, BC
location = Point(39.183 , 117.35 , 3.0)
# Get daily data for 2018
data = Daily(location, start, end)
data = data.fetch()
# Plot line chart including average, minimum and maximum temperature
data.plot(y=['tavg', 'tmin', 'tmax'])
plt.show()
下载小时数据
# Import Meteostat library and dependencies
from datetime import datetime
from meteostat import Hourly
# Set time period
start = datetime(2018, 1, 1)
end = datetime(2018, 12, 31, 23, 59)
# Get hourly data
data = Hourly('ZBTJ0', start, end)
data = data.fetch()
# Print DataFrame
print(data)
