Overview
Time series data represent data collected over a given period of time at a specific location. Time series files can contain both equidistant times series and non-equidistant series. Multiple time series can be stored in a single file. All time and date information is given in GMT unless otherwise stated. The default (and preferred) missing value definition is NaN.
A detailed description of the format is described elsewhere. In short these are XML files that can hold (scalar) time series data. Each series has a small header followed by a number of events. An event is defined by a date/time, a value and an (optional) quality flag.
The file format
Please consult the full documentation and the xsd schema as this short sample of the format is incomplete.
