Open annale2013.pdf and go to page 6, where you will find a pair of data tables with measured precipitations [sic! sarebbe dovuto essere “temperatures”] for two weather stations. The data is arranged in pairs of columns, and each pair corresponds to a month, G for gennaio (january), F for febbraio (february), etc,. until D or dicembre (december).

As for the pairs, the first column is the minimum temperature and the second column is the maximum temperature.

Each row represents a different day.

At the end of each table there are some summary data, Medie, Med.mens. and Med.norm that you can skip.

Missing data can be marked by either one or more > or < signs, or by = or be simply blank. In some tables there are extraneuous signs that you can skip outright.
Read the table and generate two different csv files, one for the maximum temperature and one for the minimum temperature, following this example

Date,Altamura,Andretta
2007-01-01,13.4, 7.7,
2007-01-02,15.7, 9.7,
2007-01-03, 7.1, 2.7,
2007-01-04, 9.5, 7.0,

The header contains the date in ISO format, YYYY-MM-DD, and the name of the weather station which is written in bold at the top of each table, just under the months. All other information in thsi area, eg., (Te), Bacino etc. is not useful and can be skipped.
