  1. TAbMEP Assessment: POLARCAT H2O Measurements

  2. Assessment Summary Table 1. Recommended POLARCAT H2O measurement treatment a The PI reported uncertainty was recommended because no IEIP precision value could be calculated for the ATR-42 Falcon data

  3. Assessment Summary Cont. Table 2. TAbMEP unified data sets • Only the DC-8 vs. DLR Falcon intercomparison meets the condition that 90% of data fall within the 2σ uncertainty bounds, making it a TAbMEP unified data set • Remaining intercomparisons contain systematic error that cannot be fully accounted for in uncertainty calculations, causing the recommended uncertainties to be insufficient for TAbMEP unified data set requirements

  4. Assessment Summary Cont. Table 3. POLARCAT H2O bias estimates

  5. Assessment Summary Cont. Table 4. POLARCAT H2O precision (1σ) comparisons
