For ERA5-complete preliminary back-extension (1950-1978, superseded now, users are advised to access the final release from 1940 instead) follow the same procedure as for era5-complete explained above, however:
edit the script to change:
| Code Block |
|---|
'reanalysis-era5-complete' to 'reanalysis-era5-complete-preliminary-back-extension'
|
Data is available for the years 1950-1978 inclusive - so make sure that your request dates are within this time period.
