-Calculate S1 SAR stats (min, max, mean, sd, q10, q50, q90). 
+# Description
 
-This service can cost an approximate of 3-5 credits per sq km. 
-This cost is based on resource consumption only and added-value cost has not been included.
+This algorithm derives temporal statistics from the Sentinel-1 GRD collection for the selected spatial- and temporal extent of interest. In order to callibrate the SAR backscatter signal, `sigma0-ellipsoid` has been applied within this workflow. 
+
+
+# Performance characteristics
+The algorithm was evaluated for a spatial extent of 20x20km, for a temporal period of 3 months. The total cost for the performed evaluation was equal to 4 credits, thereby highlighting the efficiency of the underlying algorithm.
+
+
+
+# Examples
+
+Below we show the derived minimum and maximum values for both VV and VH bands, calculated for the 20x20 km2 area of interest.
