Overview

This repository contains Jupyter notebooks that create plots seen on the home page of keelingcurve.ucsd.edu and each notebook can be altered to create custom versions of these plots. Each notebook can be opened in Google Colaboratory by clicking on the 'Open in Colab' link at the top of each notebook.

Data used in the Jupyter notebooks

The plots are created using CO2 concentration data from Mauna Loa Observatory (MLO) and a some of the plots also use ice-core CO2 concentration data. The data sources are listed below.

The Mauna Loa Observatory CO2 data is updated when there is a tweet from the Keeling Curve twitter account which occurs nearly daily. The last month of MLO data is preliminary and is subject to corrections due to factors discussed in the Data Sources section.

The ice-core data is from 800K years ago to 1957. See sources below.

MLO data from the most recent month is preliminary

Mauna Loa carbon dioxide data from the most recent month is preliminary and subject to subsequent updates to account for retrospective calibration and quality control. See scrippsco2.ucsd.edu for data that has passed these routine quality checks and updates. The datasets are archived once a month on the scrippsco2.ucsd.edu website and the Scripps CO2 Program library archive database at UCSD.

Mauna Loa Observatory CO2 Data

Mauna Loa carbon dioxide data from the most recent month is preliminary and subject to subsequence updates to account for retrospective calibration and quality control.

The datasets are archived once a month on the scrippsco2.ucsd.edu website and the Scripps CO2 Program library archive at UCSD.

CO2 data from 1958 onward are from the Scripps CO2 program
