An outline of the steps taken to go from CHIRP to CHIRPS

As of 2014.02

added use_rank to the station table

  -2  used for validation
  -1  do not use this data
   0  data OK for filling in
   1  use these stations to build anchor station list

Now have 51,352 anchor stations which produced files,

     /home/CSCD/precip_spat_params/v8/anchor_stations_lat.txt
     /home/CSCD/precip_spat_params/v8/anchor_stations_lon.txt

These files are then used by

      /home/source/pete/CSCD/chris_scripts/pete_find_neighbors.pro

to produce the outputfiles, in /home/CSCD/precip_fixed_params/monthly/v8

      neighbors.indices.img  
      neighbors.lat.img  
      neighbors.lon.img  
      neighbors.p2n_dist.img  
      neighbors.xs.img  
      neighbors.ys.img

Then we run,

      /home/source/pete/CSCD/chris_scripts/pete_calc_neighbor_distances.pro

which uses the above neighbors files to calculate distances and produce,

      /home/CSCD/precip_fixed_params/monthly/v8/neighbors.n2n_distances_km.img
