 ## Add observations to a prepBUFR file
 
-In the [previous section](obs/01-bufr.qmd) I briefly explained how to read and write a bufr file. To *add* new observations to an existing file (o to a new file!) we use the same functions mentioned [here](#an-introduction-on-how-to-read-and-write-bufr-files) and structure of the routine is also similar. But we also need to figure out how to read the new observations into fortran and how to create new reports.
