This NetCDF file was created for the manuscript: Extreme Precipitation Return Levels for Multiple Durations on a Global Scale,
Gründemann et al., 2021.
This file contain modified MSWEP-V2.2 data (Beck et al., 2019).
The python package mevpy (https://github.com/EnricoZorzetto/mevpy) was used in order to estimate the parameters and extremes.
The file "extremes.nc" contains global estimates of extreme precipitation using three extreme value methods (GEV, POT and MEV)
and the observed extremes, for 8 durations ranging between 3 hours and 10 days. The spatial resolution is 0.1 arc degrees, and the
provided coordinates are the middle of the grid-cells.
GPEX.nc has the following coordinates:
- lat latitude The latitude coordinate: 1480 values and ranges between 89.95 and -57.95 degrees north
- lon longitude The longitude coordinate: 3600 values ranges between -179.95 and 179.95 degrees east
- dur event duration The duration of the extreme precipitation event: 3, 6, 12, 24, 48, 72, 120 and 240 hours
- tr return period The return period of the extreme precipitation: 2, 5, 10, 20, 39, 50, 100, 200, 500, 1000 years
- year year 38 values (ranging between 0 and 37), equal to the number of years of the MSWEP dataset
