If your data is accumulated for a time period (a day, ...), then you have interval time. If your data represent a value that is valid for a specific time period (daily mean), you have interval time.

Sören, Thank you for clarifying. We all use terms for which we have specific definitions while others have their own definitions that are different. That's why I want to be sure we're both using the same definition.
The next thing to consider is, what you want to do with the data. If you want to compute interactions with other time series, then it makes sense to use time intervals to compute temporal overlapping and intersection.
These data will be part of the input to Itzi models of flat land surface hydrology. They are the only variable contributing to water depth by time and place. Very much appreciated, Rich _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
