About

emipy is a package for processing data of pollutant releases and pollutant transfers. It's main target is to enable a fast output of individual data set requests and to provide visualisation options.

Documentation

To do

Quick start

The quickest installation is via the package manager pip:

pip install emipy

Inside the environment one can access the three modules rawdata/filter/plot and respective functions with:

from emipy import module_name

module_name.function_name()

At first the data have to be prepared for data requests. Create a folder for your project, and add a folder "rawdata" inside of it. Then execute the following lines with 'path', the project folders path. (Remark: All backslashs have to be doubled)

rawdata.download_url('path')
rawdata.pickle_rawdata('path')
rawdata.merge_frompickle('path')

By now there is a data base with complete information which we can call by:

filter.read_db('path')

The output is a dataframe which is used as an input for further processing functions. A short example for a data request and visualisation:

db = filter.read_db('path')  #loads data frame
DE = filter.f_db(db, CountryName='Germany',	PollutantName='Carbon dioxide (CO2)')   #filter for Germany and CO2
plot.plot_PollutantVolume(DE)   #Plots the CO2 release in Germany against the year

Requirements

This package uses pandas and matplotlib.
