Project description

气象数据读写及访问程序库

提供对MICAPS文件, 卫星云图, 天气雷达等数据的读写程序, 并访问CMADaaS, CIMISS和MICAPS CASSANDRA数据库文件等.

Only Python 3 is supported. 建议安装Anaconda数据科学工具库, 已包括scipy, numpy, matplotlib等大多数常用科学程序库.

Install

Using the fellowing command to install packages:

  pip install nmc-met-io
  • 若要安装Github上的开发版(请先安装Git软件):
  pip install git+git://github.com/nmcdev/nmc_met_io.git
  • 或者下载软件包进行安装:
  git clone --recursive https://github.com/nmcdev/nmc_met_io.git
  cd nmc_met_io
  python setup.py install

可选支持库:

  • 若需要实现对grib格式数据的读取, 请用conda安装:

    • eccodes, conda install -c conda-forge eccodes(ECMWF的grib工具库, 支持Windows和Linux)
    • cfgrib, conda install -c conda-forge cfgrib
  • 若需要使用将标准雷达格式转化为pyart格式程序standard_data_to_pyart, 请安装:

    • arm_pyart, conda install -c conda-forge arm_pyart

设置配置文件

若要访问CIMISS、CMADaaS或MICAPS服务器等, 需在配置文件中设置地址和用户信息(若不需要, 则相应项无需配置).

  • 在系统用户目录下("C:\Users\用户名"(windows)或"/home/用户名/"(Linux)), 建立文件夹".nmcdev"(若Windows下无法直接创建, 在命令窗口中输入mkdir .nmcdev创建)
  • 在".nmcdev"中创建文本文件"config.ini", 内容模板为:
[CIMISS]
DNS = xx.xx.xx.xx
USER_ID = xxxxxxxxx
PASSWORD = xxxxxxxx

[CMADaaS]
DNS = xx.xx.xx.xx
PORT = xx
USER_ID = xxxxxxxxx
PASSWORD = xxxxxxxx
serviceNodeId = NMIC_MUSIC_CMADAAS

[MICAPS]
GDS_IP = xx.xx.xx.xx
GDS_PORT = xxxx

# Cached file directory, if not set,
#   /home/USERNAME/.nmcdev/cache (linux) or C:/Users/USERNAME/.nmcdev/cache (windows) will be used.
[CACHE]
# CACHE_DIR = ~ 

[MAPBOX]
token = pk.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

这里xxxx用相应的地址, 接口和用户信息代替. 如果要用到MAPBOX地图, 可以申请access token.
