It was discovered that the colder the inlet tube (correlating to higher altitudes) the lower our sensitivity because of the accelerated wall losses. The overall changes to the originally archived data (and subsequently in the Harvard merge files) are now between 0-30% with significant vertical gradients; therefore, this will affect the vertical structure of the HOx fields. The changes are between 15-25% for HO2 and 25-30% for OH at the highest altitudes (larger concentrations in both cases in the revised data set.) The changes at lower altitudes are smaller, with HO2 changing between -10 to +15%, and OH changing -5% to +18%. The one notable exception is flight #21 (April 17, 1999) for which incorrect calibration factors were used to reduce the data originally, thus the change in these data are 190-215% for OH (increasing), and 20-30% for HO2 (decreasing). ----------------------------------------------------------------------------- 1.1 Singh - Ames Research Center Singh confirmed Final data: -- PAN, C2Cl, Methyl Nitrate, and Ethyl/i-Propyl Nitrate files: shgc1dxx.pmb (xx = 4-22) on 11/22/1999 CHANGES -- shgc1d05.pmb on 02/02/2000 corrected variable definition for i_Propyl_Nitrate and rescanned CHANGES -- shgc1dxx.pmb on 03/06/2000 changed variable name i_Propyl_Nitrate to Ethyl/i-Propyl_Nitrate -- Acetone, Methanol files: shgc3dxx.pmb (xx = 4-22) on 11/22/1999 ----------------------------------------------------------------------------- 1.0 Gregory - NASA/LaRC: Gregory confirmed Final data: -- Ozone files: gg_ozdxx.pmb (xx=05-07;09-13;15-21) on 10/12/1999 gg_ozdxx.pmb (xx=08;14;22) on 10/14/1999 ----------------------------------------------------------------------------- 1.1 Heikes - Univeristy of Rhode Island Heikes confirmed Final Data: -- FORMALDEHYDE hbfordxx.pmb (xx=05-22) on 11/02/1999 -- HYDROGEN PEROXIDE, METHYL-HYDROPEROXIDE hbperdxx.pmb (xx=04-22) on 11/02/1999 CHANGES -- hbperdxx.pmb (xx = 4-22) on 06/05/2000 A 9 minute time offset has been subtracted from the earlier submissions and was needed to correct for the time delay between sample collection time and its injection into the HPLC system. The time correction can cause a change in reported values. H2O2 changes are minor. CH3OOH changes are slight during horizontal flight but are more pronounced during periods of rapid ascent or descent. ----------------------------------------------------------------------------- 1.0 Shetter - NCAR: Shetter confirmed Final Data: -- J values files: rsjv1dxx.pmb (xx = 02-22) on 12/03/1999 -- actinic flux as a function of wavelength files: rsflxdxx.pmb (xx = 02-22) on 12/03/1999 ----------------------------------------------------------------------------- 1.0 Sachse - NASA/LaRC: Sachse confirmed Fianl data: sgdacdxx.pmb (xx = 05-22) on 11/29/1999 sgdewdxx.pmb (xx = 05-22) on 01/21/2000 sgfvpdxx.pmb (xx = 05-22) on 02/18/2000 ----------------------------------------------------------------------------- 1.2 Sandholm - Georgia Tech Sandholm confirmed Final Data: -- NO files: sslifdxx.pmb (xx=05-22) on 11/02/1999 -- NO2 files: ssno2dxx.pmb (xx=05-22) on 12/22/1999 CHANGES -- ssno2dxx.pmb (xx=06-22) on 01/28/200 header file corrected to reflect the correct variable names CHANGES -- ssno2d20.pmb on 02/02/2000 corrected LOD values in header and rescaned ----------------------------------------------------------------------------- 1.1 Talbot - University of New Hampshire Talbot confirmed Final data: -- Aerosol files: nhaerdxx.pmb (xx = 5-22) submitted on 11/15/1999 -- Acidic Trace Gas files: nhatgdxx.pmb (xx = 05-22) submitted on 11/30/199 CHANGES -- Aerosol files: nhaerdxx.pmb (xx = 5-22) re-submitted on 2/5/2001.
