<dataset type code>
Comment: The dataset type code describes whether the time spacing of the dataset is strictly homogeneous (code "TU", meaning time-series, uniform), or whether the user has to expect gaps and shifts in the timesamp (code "TI", meaning time-series, irregular). For files submitted to WDCA as regular submission, it is required during the processing and quality assurance process to aggregate the data to hourly averages, and to pad holes with missing value codes. The type code is therefore always TU for a regular data submission.
