Appendix F Data format of weather data

The following information consists of excerpts from the C++ source program,
and aims to clarify the data structure of the weather data file.
The weather data file is a sequential file in which all received data are stored
consecutively in a data record of constant size (WSPC_DATA).
At the beginning, there is a 4 byte integer containing flags: these indicate the
availability of sensors.
Successive data records follow this as they are received from the interface.
