Description:
This CO2 data is available in the R package `fields' except that the data here has been converted into a more user-friendly long-table format. In the package contains the following data description:
This is an example of moderately large spatial data set and consists of simulated CO2 concentrations that are irregularly sampled from a lon/lat grid. Also included is the complete CO2 field used to generate the synthetic observations.
This data was generously provided by Dorit Hammerling and Randy Kawa as a test example for the spatial analysis of remotely sensed (i.e. satellite) and irregular observations. The synthetic data is based on a true CO2 field simulated from a geophysical, numerical model.
Format:
co2sim.csv
The CSV file has three columns:
lon: longitude coordinate.lat: latitude coordinate.z: CO2 concentration in parts per million.
co2true.csv
The CSV file has three columns:
lon: longitude coordinate.lat: latitude coordinate.z: CO2 concentration in parts per million. mask: logical vector that indicates with grid locations were selected for the synthetic CO2 dataset.
