What was done to it

  1. Read the sheet 'Splines fits' of Law_Dome_GHG_2000years.xlsx, CSIRO collection version v3 (data last updated 11/2018).

    Code: pipeline/src/envdash/transforms/air/law_dome_co2.py · code sha256 c67459fecb8e83fe… · inputs e2fb9ef0b36b…

  2. Published the column 'CO2 spline (20 yr, ppm)' as printed for each year of its 'Year AD' column, 0154 to 1996, as ISO calendar years. The spline is CSIRO's fit to the ice and firn measurements, which halves variations with periods shorter than 20 years; the growth-rate column and the individual samples are not published here.

What it covers

Geography
Law Dome, East Antarctica (66.7° S, 112.8° E)
Basis
Smoothing spline (Enting 1987) through ice-core (DSS, DSS0506, DE08, DE08-2) and firn-air (DE08-2, DSSW20K) measurements by gas age; variations with periods under 20 years are halved.
Unit
parts per million (ppm)
