New App: NOx emissions

import data from :

edgar_htap_nox_emissions.nc

(derived from original_data_files/edgar*.nc via make_edgar_nox_totals.py)

This file uses the HTAP_V2 2010 NOx emissions inventory.
This dataset consists of 0.1deg x0.1deg gridmaps (lat-lon at center of each grid cell) of NOx emissions (reported as NO2) for the year 2010.
It uses nationally reported emissions combined with regional scientific inventories in the format of sector-specific gridmaps. The gridmaps
are complemented with EDGARv4.3 data for those regions where data are absent. The global gridmaps are a joint effort from US-EPA, the
MICS-Asia group, EMEP/TNO, the REAS and the EDGAR group to serve the scientific community for hemispheric transport of air pollution.

Scripts:

• make_edgar_nox_totals.py:
  • adds up the individual sector emissions in the original_data_files to create one total NOx emissions file. Sectors considered are: ENERGY, INDUSTRY, RESIDENTIAL, SHIPS, TRANSPORT, AIR_LTO (aircraft landing and takeoff). Aircraft emissions at cruise altitudes are not considered.
• extract_nox_emissions.py:
  • extract NOx emission values at all TOAR database stations. Original values in units of kg m-2 s-1 are converted to g m-2 yr-1 to obtain numbers in easy decimals. Original longitudes range from 0..360 and are converted to -180..+180.
