This probe has an open sample cavity and uses both forward scattering and diode-array imaging to size cloud particles. In collaboration with the probes manufacturer, we have recently completed a characterization study of the probe and found that the measured sample volumes for both its forward scattering and imaging sections were significantly larger (up to a factor of eight, depending on particle size) than the modelled values used in reducing the TRACE-P data set. We have thus corrected the CAPS data and re-submitted the "abopcdNN.trp" files to the GTE TRACE-P archive. The parameters that changed include: "Number_20-50","1/cm3@stp" "Number_50-1550","1/cm3@stp" "Surface_20-50","um2/cm3@ambient" "Surface_50-1550","um2/cm3@ambient" "Volume_20-50","um3/cm3@ambient" "Volume_50-1550","um3/cm3@ambient" "LWC_Calc","g/m3@stp" Please note that these parameters have non-zero values only during cloud penetrations and that the changes do not effect the "cloud-index" files found on the archive. ----------------------------------------------------------------------------- 1.2 Apel - NCAR: Apel confirmed Final Data: -- Carbonyls, alcohols APOXYD??.trp (?? = 04 - 20) on 01/07/2002 CHANGES -- Removed ALL Ethanol measurements on (11/05/2002). Reasons: We request that the Apel ethanol measurements be removed from the TRACE-P DC-8 database. We discovered this when we recently upgraded our system, exposing this problem. In the old configuration, used during the experiment, we had a peak that co-eluted with ethanol with the same ion used for ethanol quantitation. The magnitude of the interference was dependent on altitude. The net effect was to cause the ethanol values to be higher than the actual values and variable. CHANGES -- Reassesment of carbonyl and alcohol measurement uncertainties (11/20/2002): Measurement Uncertainties: acetaldehyde +/- 60 pptv methanol +/- 85 pptv propanal +/- 25 pptv acetone +/- 75 pptv butanal +/- 12 pptv methyl ethyl ketone +/- 8 pptv ----------------------------------------------------------------------------- 1.0 Atlas - NCAR: Atlas confirmed Final Data: -- Alkyl nitrates, Halocarbons files: NCGC_D??.trp (?? = 04 - 20) on 12/07/2001 CHANGES -- ----------------------------------------------------------------------------- 1.0 Avery - LaRC/NASA: Avery conformed Final Data: -- OZONE files: ma_ozd??.zip (?? = 04 - 20) on 11/02/2001 CHANGES -- ----------------------------------------------------------------------------- 1.0 Blake - UCI: Blake confirmed Final data: -- Halocarbons, Non-methans Hydrocarbons files: UCGC_D??.TRP (?? = 04 - 20) on 11/01/2001 CHANGES -- ----------------------------------------------------------------------------- 1.0 Browell - LaRC/NASA: Browell confirmed Final Data: (DIAL) -- Composite Tropospheric Ozone Cross-Sections files: beoz1d??.trp (?? = 04 -20) on 11/20/2001 -- IR Aerosol Scattering Ratio (1064 nm) files: beir1d??.zip (?? = 04 - 20) on 12/10/2001 -- Visible Aerosol Depolarization files: bedp1d??.zip (?? = 04 - 20) on 12/10/2001 -- Visible Aerosol Scattering Ratio files: bevs1d??.zip (?? = 04 - 20) on 12/10/2001 -- Tropopause heights and ozone columns files: betc1d??.zip (?? = 04 - 20) on 12/10/2001 -- DIAL Aerosol Wavelength Dependence - 1064 nm / 587 nm files: bewd1d??.zip (?? = 04 - 20) on 12/10/2001 ----------------------------------------------------------------------------- 1.1 Brune - Penn State University: Brune confirmed Final Data: -- OH/HO2 files: BWHOxD??.TRP (?? = 04 - 20) on 12/17/2001 CHANGES -- Brune resubmitted all OH/HO2 files BWHOxD??.TRP (?? = 04 - 20) on 10/04/2002.
