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 (CO2.true) used to generate the synthetic observations.
Format
The CSV file has three columns, lon, lat and z. The lon, lat fields are the longitude/latitude locations. These are a subset of a larger lon/lat grid. The z field is the CO2 concentration in parts per million. CO2.true also contains the field `mask'. This is a logical vector that indicates with grid locations were selected for the synthetic data set CO2.
Details
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.
