Area weighted time series of extreme prcp
Added by David Sagi about 1 month ago
Dear all,
I am kind of new to CDO and i am trying to create a global time series of percentage of areas under higher rainfall (prcp > 100 mm) for the period 1979-2025. Can any help me review my code if i am doing right?
Land mask: grid cells with valid precipitation at least once during the whole period. Missing values in the dataset are currently defined as 1.e+30f
cdo setmisstoc,0 -ltc,1e10 -timsum Prcp_1979-2025.nc landOnly.nc
Total land area
cdo fldsum -mul landOnly.nc -gridarea Prcp_1979-2025.nc Total_land_area.nc
Area with extreme rainfall (precipitation > 100 mm)
cdo fldsum -mul -gtc,100 Prcp_1979-2025.nc -gridarea Prcp_1979-2025.nc Area_extreme_rainfall.nc
Percentage of area with extreme rainfall
cdo mulc,100 -div Area_extreme_rainfall.nc Total_land_area.nc percent_area_extreme_rainfall.nc
