Data gridding - SatCO2

Data gridding includes two modules: “resampling” and “gridding.”
Resampling: Modify the spatial resolution of the whole image. After clicking the button, the calculation dialog box (Figure 2-53) pops up. Select the loaded satellite data and click “OK” to start data resampling after setting a new grid resolution. The new resampled image will be automatically displayed on the 3D geosphere (Figure 2-54b).

Figure 2‑53. Settings for satellite data gridding. The resolution of 0.25° (25-km) SST data is resampled into 0.0417° (4-km) resolution.

Figure 2‑54. Satellite data gridding. (a) AVHRR SST data with 0.25° (25-km) resolution; (b) SST data after the gridding to 0.0417° (4-km) resolution. This function can be used to achieve the consistency of spatial resolution of satellite products and facilitate further analysis.

In situ data gridding: Click the “gridding” button, and the calculation dialog box will pop up (Figure 2-55). Select the loaded in situ data, set the required gridding parameters and grid resolution, and click “OK” to grid the data. The system automatically displays the grid results on the 3D geosphere (Figure 2-56). If air-sea CO2 flux (FLX) is gridded, the gridding results can be further evaluated for the carbon budget by area integral.
