Description of Profile Plols
There are four plots for each flight:|
Plot 1 scattering coefficient at 550 nm vs altitude absorption coefficient at 565 nm vs altitude (adjusted to STP conditions) |
Plot 2 ambient temperature vs altitude ambient humidity vs altitude reference nephelometer humidity humidified nephelometer humidity |
|
Plot 3 co-albedo (1 - single scattering albedo) back-scatter fraction |
Plot 4 green/red Angstrom coefficient f(RH) (post-May 2003) green/blue Angstrom coefficient (pre-May 2003) |
The asterisks (*) on plots 1, 3, and 4 represent surface measurements of
aerosol optical properties from SGP.
The plots are organized by quarter.
Flights are identified by date (consisting of year and day of year (DOY)), flight # (A for the first flight, B for the second flight and so on), and by flight location (typically CART for over the CART site). Ideally all flights would take place directly over the CART site, however if air traffic control determines conditions are unsafe then the profile is made over one of several sites near the CART site. The designations for these other locations are: H76 and OK56.
