Artificial Precipitation QA

• Summary of Artificial Precipitation Checks
  • How Big an Impact Does This Have?
  • Quality Checks/Rules
    • Flag double delayed precip
      • Example
    • Flag repeating values
      • Example
    • Flagging Estimates of empty tanks
      • Example
• Finding Artificial Precip
  • False precip with flat tank
    • Compare to raw data
  • Filtering for a flat tank
    • Max == min
    • Max==min w/ a buffer
    • QaRules.flag_duplicate_precip
      • minimum_ppt > 0
      • minimum_ppt > 0.2794
      • minimum_ppt > 0.2794 / 2
      • minimum_ppt > 0.196
      • Identical precision for flat and repeat
      • Requiring consecutive values
  • Comparing tank change to precip
    • Rolling sum of tank
      • 1 Day
      • 1Hr
    • QaRules.flag_overaccum_precip
      • Only where precip > tank
    • Smooth tank first
