Anderson Harvard University, Cambridge, MA 02138; Tel (617) 495-5922 Harvard NO2 SOLVE 1 1 2000 01 11 2001 10 23 0 Elapsed time (sec) from 0 GMT on flight day 1 1.0 999999.9 NO2 Volume Mixing Ratio (pptv) 8 FINAL DATA Estimated Accuracy (2 sigma): +/- 20 percent Estimated Zero Offset error (2 sigma): + 35 /- 10 ppt NO2 measurements during deep vortex flights with high ClO concentrations suggest a systematic offset of ~10 to 15 ppt ppt. We recommend accounting for this offset in the analysis of SOLVE data. For more information on flight-specific errors or instrument specifics, please contact the investigators. 2 ********** FINAL DATA ********** Time NO2 48705.25 68.5 48720.25 48.6 48730.25 47.0 48740.25
