co2-ppm-daily
This dataset contains near‑continuous daily measurements of atmospheric dry‑air carbon‑dioxide mole fraction taken at Mauna Loa, Hawaii. The record spans from 1 January 1958 to 31 December 2017, and continues up to the present day, aggregating multiple sources to ensure all available values are included. Values are reported in micromoles per mole of dry air (10⁻⁶ mol/mol), equivalent to ppm.
