Flight Mission Details
This was P-3B twentieth 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.
