As of 2014.01.27 decided to do a complete rerun of CHIRPS to be called CHIRPS v1.8

Currently Monthly 1.7 CHIRPS were last run in mid November. 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 [chirps_rchecks | 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,

recalc neighbor station statistics recalc master locations

pre-compute spi for all master locations (month/pentads)

go thru

  Merge
  QC
  Blend

Do some reality checks on results.

create all the related CHIRPS files.



Fixes etc.

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

CHIRP may-September 2013 glitch

   changed CHIRP calc script for a while, will redo entire CHIRP timeseries with current script
