Introduction

ccg is a program which enables you to plot ERSL atmospheric gas data from the US National Oceanic and Atmospheric Administration (NOAA) web site.

Install

sudo apt install gnuplot python3

Usage

For Carbon Dioxide:

cd data
rm -rf surface_co2
wget https://gml.noaa.gov/aftp/data/trace_gases/co2/flask/surface/co2_surface-flask_ccgg_text.tar.gz
tar -xzvf co2_surface-flask_ccgg_text.tar.gz
mv co2_surface-flask_ccgg_text surface_co2
cd ..
python3 ccg2.py --title "Atmospheric CO2"
ls *.jpg *.kml

For Methane:

cd data
rm -rf surface_ch4
wget https://gml.noaa.gov/aftp/data/trace_gases/ch4/flask/surface/ch4_surface-flask_ccgg_text.tar.gz
tar -xzvf ch4_surface-flask_ccgg_text.tar.gz
mv ch4_surface-flask_ccgg_text surface_ch4
cd ..
python3 ccg2.py --title "Atmospheric CH4" --dir data/surface_ch4
ls *.jpg *.kml
