Appendix F Weather File Data Format

The information below is comprised of extracts from the C++ source program in
order to make the structure of the weather data file more clear.
The weather data file is a sequential file in which all the data received is stored in
succession in one dataset of constant size (WSPC_DATEN).
At the start of the file is a 4-byte integer, containing flags which indicate the
presence of sensors.
This is followed by consecutive datasets as received from the interface.
