- •
Rainfall erosivity in Greece is estimated to 807 MJ mm ha− 1 h− 1 year− 1.
- •
Cold season is three times more erosive than the warm one.
- •
Spatial analysis shows a gradient of high R-factor in Western Greece & Peloponnesus.
- •
R-factor has a high intra-annual variability with the highest value in November and lowest in July.
- •
Monthly erosivity density (ratio of R-factor to precipitation) identifies months with rainstorms.
