download_co2_ml: Mauna Loa Atmospheric CO2 Concentration (Latest Data)

In andreas50/utsData: Example Data Sets of Unevenly Spaced Time Series

Description

This function downloads the monthly average atmospheric CO2 concentration (in parts per million), as measured at the Mauna Loa observatory, from a website by the NOAA Earth System Research Laboratory. The downloaded data is subsequently imported into R and returned as a uts object.

Usage

download_co2_ml()

See Also

Users without internet connection can access the already imported data via co2_ml. However, to get the most recent data it is recommended to use this function.

co2_20ma for a 20 million year reconstruction.

The co2 dataset in base R is very similar, but ends in 1997 and has several missing values filled in using linear interpolation.

Examples

co2_ml <- download_co2_ml()
plot(co2_ml)
table(round(diff(co2_ml$times) * 12 / 365))  # most observations are one month apart

# Save data
## Not run: 
  save(co2_ml, file=file.path("data", "co2_ml.rda"), compress="xz")

## End(Not run)
