-Time series of map layers are managed in space time datasets, a new data type in GRASS GIS,
-and are still accessible also as individual map layers.
-Based on the GRASS GIS Temporal Framework Python application programming interface (API),
-more than 50 modules were implemented to manage, analyze, process
-and visualize space time datasets.
-More than 100,000 map layers can be now handled efficiently in GRASS GIS.

-Example usages of this functionality include
-analysis of the
-European Climate Assessment \& Dataset ECA\&D \citep{Haylock2008_climate_series}
-and temperate climate zone in the European Union identification \citep{Gebbert20141}.
-The new temporal modules (staring with \gmodulenolink{t.})

-and specialized modules such as \gamodule{r.hants} implemented according to \cite{roerink2000reconstructing}
