MSWEP¶
Overview¶
We have replicated the monthly, daily, and 3hourly Multi-Source Weighted-Ensemble Precipitation (mswep) data from GloH2O.
MSWEP is a global precipitation product with a 0.1° resolution available from 1979 - 2020. The product is unique in that it merges gauge, satellite, and reanalysis data to obtain the highest quality precipitation estimates at every location. MSWEP incorporates daily gauge observations and accounts for gauge reporting times to reduce temporal mismatches between satellite-reanalysis estimates and gauge observations. MSWEP is compatible with GloH2O’s operational Multi-Source Weather (MSWX); MSWX forecasts can thus be used to extend MSWEP into the future. MSWEP tends to exhibit better performance than other precipitation products in both densely gauged and ungauged regions (see Beck et al., 2017, and Beck et al., 2019).
This is an extract of the dataset description from the website where you can find more information on this data. We replicated only the historical precipitation data, if the realtime data is required then please open a new issue in https://github.com/aus-ref-clim-data-nci/mswep/issues
Data download¶
The data is downloaded from a google drive hosted by https://www.gloh2o.org. The data is monthly, daily, and 3hourly historical data from 1979 - 2020.
The script uses rclone, to run:
bash mswep.sh -f <freq>.
Where <freq> is mon, day, or 3hr.
The code used to concatenate the files is a bash script calling CDO:
bash mswep_concat.sh -f <freq>
Note: rclone was used to download this data from Google Drive. This required me to add the MSWEP shared folder to my Drive and link rclone to my Drive account. If more up-to-date MSWEP data is released in the future then the user running the download script needs to add the shared folder and link rclone.
Data location¶
We’ve downloaded the MSWEP netCDF data to:
/g/data/ia39/aus-ref-clim-data-nci/mswep/data/<freq>/mswep_v280_<freq>_<year>.nc
Where <freq> is mon, day, or 3hr; <year> is a year in the range 1979 - 2020. The Monthly, Daily, and 3Hourly data have been concatenated into yearly files.
