GPCC

Global Precipitation Climatology Centre  

The GPCC provides gridded gauge-analysis products derived from quality controlled station data. There are different products available, we only downloaded the full reanalysis. The latest version of the full reanalysis is V2020 monthly and daily that covers from 1891 to 2019. The data is available on 4 global grids for monthly and only at 1.0  degrees resolution for daily:

• 0.25 degree latitude x 0.25 degree longitude global grid (1440 x 720) - only monthly
• 0.5 degree latitude x 0.5 degree longitude global grid (720 x 360) - only monthly
• 1.0 degree latitude x 1.0 degree longitude global grid (360 x 180)
• 2.5 degree latitude x 2.5 degree longitude global grid (144 x 72) - only monthly

The data is not bias-corrected for gauges errors, but estimates on these are also provided. More information and a visualization tool for the dataset is available on the GPCC website. For a review of the data check the UCAR Climate Data Guide. The data was downloaded from the  GPCC data server.

GPCC at NCI

GPCC is replicated in the Precipitation collection in the ua8 project:

/g/data/ua8/Precipitation/GPCC

The directory structure is

/<version>/<frequency>/<grid>/<files>

where frequency is 'mon' or 'day'

grid is:

• 025 - for 0.25X0.25
• 05 - for 0.5X0.5
• 10 - for 1.0X1.0
• 25 - for 2.5X2.5
