CHIRPS v1.8
As of 2014.01.27 decided to do a complete rerun of CHIRPS to be called CHIRPS v1.8
Monthly 1.7 CHIRPS were last run in mid November 2013. These have the problem with flipping the order of the neighbors used to fill in master locations.
- Ingest new station data,
Brazil (junior) World Bank coffee countries: Guatemala, Honduras, Nicaragua Panama New GTS? GSOD?
- Exclude bad Zambia data
- Address problem Brent found with daily September data in the Horn.
- Run some reality checks on the station data in the db.
- Verify the code fix that was flipping the neighbor list is included in this run
Found something wrong with CHIRP data for June-August 2013. # of pixels with positive rainfall plummets. As much as 60% in S. Africa. Does not seem physically possible.
Finalizing
Once all stations finalized:
- recalculate neighbor station statistics
- recalcu;ate master locations
- pre-compute SPI for all master locations (month/pentads)
- go through CHIRPS MQB
Merge QC Blend
- Do some reality checks on results.
- create all the related CHIRPS files.
Fixes, etc.
