WP-3D Data Notices

Dec 15, 2006
Google Earth files posted for each flight. Also final AOC data is coming soon.

Dec 28, 2006
Final data is due Friday, February 16, 2007. Please use the same ftp site as for field data.

Jan 8, 2007
Final AOC data now posted on the website. The AOCTimewave is unchanged from the preliminary data.

Feb 26, 2007
Final data posted for CO, Ethylene, HNO3, PANs, SO2, PTRMS, AMS, CRDExt, PILS.

Feb 28, 2007
Final 1 s SP2 data from the WP-3D has been posted to the archive for TexAQS2006. This data has a 25 to 30% systematic uncertainty due to flow and mass calibration, and aspiration efficiency. This does not include statistical uncertainty. Statistical uncertainty can be obtained by averaging the data over longer time periods, but is insignificant in plumes.

Mar 13, 2007
Final data is posted for J Values from ZAPHROD.

Mar 21, 2007
Final 10 s SP2 data from the WP-3D has been added to the archive for TexAQS2006. This data has a 25 to 30% systematic uncertainty due to flow and mass calibration, and aspiration efficiency. This does not include statistical uncertainty. Statistical uncertainty can be obtained by averaging the data over longer time periods, but is insignificant in plumes. The 1 s data remains the same.

Apr 10, 2007
Final CO2 data from Jeff Peischl has been posted to the archive.

Apr 16, 2007
Final NO/NO2 data from Tom Ryerson has been posted to the archive. (Final NOy is coming soon). Also NO/NO2/NOy are now in separate files.

Apr 16, 2007
The AMS folks have found problems with their data on 9/20, 9/25, 10/10, and 10/12. Those files have been removed from the archive and will be updated with new data.

Apr 20, 2007
I posted new Aircraft Position files for 20060915, 20060916, 20060919, 20060920, 20060925 and 20061012. The only difference in these new files is that gaps of <10 seconds have been interpolated.

Apr 23, 2007
Revised C-ToF AMS data (Rev 2) with corrected collection efficiency for all flights except those on Sept. 20, Sept. 25, Oct. 10, and Oct. 12 are now available on TexAQS2006 data archive.

Apr 30, 2007
Revised C-ToF AMS data for flights on Sep. 20, Sep. 25, Oct. 10, and Oct. 12 are now available on the archive.

May 3, 2007
Final NOy data is now available on the archive.

May 7, 2007
Final NH3 data is now available on the archive. For the 8/31 transit flight no data ever available. For the flights on 9/11, 9/13, 9/15, in general, no data available due to MFC problem. Data may be available for certain sections over the Gulf of Mexico. See John Nowak if you are interested.

May 8, 2007
PILS Cation data for 9/16, 9/19, and 9/21 have been removed from the archive due to an interference with the cation measurements that caused a systematic error.

May 14, 2007
NAerosol file submitted for 20060911.
WAS data is now in the archive for all flights from 9/19 to the end of the mission. Data merged onto the WAS time base is coming soon.

May 18, 2007
I posted a data set called AllWASmerge which has data on the WAS time base, and has all flights concatenated.

May 25, 2007
New NO3N2O5 files (R1) from Steve Brown are posted for 9/29, 10/8, 10/10/ 10,12 and the AllWASmerge file for NO3N2O5.

June 8, 2007

RHB Data Notices

Dec. 15, 2006
The files on the DataDownload page are now formatted into one file for the whole cruise for each species. There is no gap in the time between the two legs, so for the instruments that were not taking data during that time, it will be filled in with missing values (-9999 for the icartt files and NaN for the Igor files).

Mar. 1, 2007
Final data is posted for CO, CO2, H2O, HCHO, NOy, O3, SO2, VOCs, Aerosols, j Values.
