Flight Mission Details

This was P-3B thirteenth flight out of Bloomfield Municipal Airport, Colorado. The aircraft took measurements over the six D-AQ sites: Fort Collins/site-1, Platteville/site-2, Golden NREL/site-3, BAO Tower/site-4, Denver/La Casa/site-5, and Chatfield Park/site-6.

Key instruments on P-3B include:
1. LARGE (Langley Aerosol Research GroupE): aerosols.
2. PDS (Project Data System): base meteorological and navigational measurements.
3. TD LIF: NO2, HNO3, PNs, ANs;
4. DLH (Diode Laser Hygrometer), H20.
5. DACOM (Differential Absorption CO Measurement): CO, CH4
6. DFGAS (Difference Frequency Generation Absorption Spectrometer): CH20
7. Chemiluminescence (NCAR 4-channel Chemiluminescence Instrument): O3, NO2, NO, NOy
8. PTR-MS (Proton-Transfer-Reaction Mass Spectrometer): non-methane hydrocarbons.
9. AVOCET (Atmospheric Vertical Observations of CO2 in the Earth's Troposphere): CO2.
10. CAR (Cloud Absorption Radiometer): scattered light and surface radiance that is reflected off of surfaces.
11. Fast Ethane Spectrometer: ethane, methane.


Flight Path, Timing, and Measurements

Approximate time in UTC (Colorado, -6 hours). Activities during CAR flight 2050 on August 12, 2014 out of Bloomfield Municipal Airport. Observations by CAR operator/PI, Charles Gatebe.

13:10 -- Preflight checks done. Powered CAR and CANS instruments. All systems seemed ok.
13:24 -- running the CAR with modified LabView code, which is supposed to correct the math problem in the X-link.
13:35 -- aircraft door closed.
13:42 -- aircraft engines start.
13:47 -- taxiing
13:48 -- Ch 9 set to 2.1 µm.
13:53 -- take off.
13:54 -- CAR door fully open.
13:55 -- Ch 9 shows a spike in the data. Need to investigate.
