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
  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.


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

Fixes, etc.

Zambia-Met pptx here,

Fixed a bunch of station locations in the stations table

Use the same landmask everywhere, avoid variations in the ocean/land boundary
