  19. Summary of the summaries! Pressure: [RS92-RS92] < 1 hPa for all but 3 of 14 flights [RS92-IMet] 8 of 20 flights with inconsistent differences of 5-25 hPa Temperature: [RS92-RS92] < 0.5°C for all but 2 of 14 flights [RS92-IMet] 16 of 20 have consistent bias of about 0.5°C (RS92 > Imet) Altitude: [RS92-RS92] almost all differences < 100 m for 14 flights [RS92-IMet] majority of differences < 100 m, but some as large as 600 m RH: Imet data is garbage [RS92-RS92] < 1% RH for all but 3 of 14 flights [FP-RS92] most flights agree to within 2% RH, but RHFP +1-2% RH [FP-FP] 2% RH bias from RS92-Imet T bias: RH(FPRS92) < RH(FPIMET) H2O VMR: [FP-FP] 1-2% differences from RS92-Imet Pressure differences H2O(FPRS92) < H2O(FPIMET) because PRS92> PIMET, especially in stratosphere MOHAVE 2009 Data Workshop II Oct 18-21, 2010
