Hi I have extracted the following gridded data from an interpolation. Then I averaged the interpolated data from a ten-year period and they now look like this:
Unnamed: 0 index latitude longitude value
0 0 0 8.681598e+05 5.650097e+06 -5.282287
1 1 1 8.681598e+05 5.713078e+06 -5.296532
2 2 2 8.681598e+05 5.776060e+06 -5.310595
3 3 3 8.681598e+05 5.839042e+06 -5.324469
4 4 4 8.681598e+05 5.902023e+06 -5.338146
... ... ... ... ... ...
How can I plot this data again in Basemap with contourf?
