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
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
