for additional information.The horizontal display interval of the full flight images depends on the length of the flight. Both nadir and zenith data may be imaged separately or together, with a
black trace appearing at the aircraft altitude. Only one color scale (logarithmic) is used for the aerosol images. Aerosol data are reported as Atmospheric Scattering Ratios on a logarithmic scale. Water Vapor data are reported as mixing
ratios (g/kg) on both a Linear and logarithmic scale.
Resolution of CAMEX-4 LASE Image data are:
Vertical averaging interval
Aerosol
Nadir 60 meters
Zenith 60 meters for flight 8,10,11, and 12 (all other flights
have vertical resolution of 2 km)
Water Vapor
Nadir 330 meters
Vertical display interval for averaged data
Aerosol 60 meters
Water Vapor 30 meters
Horizontal averaging interval
Aerosol
Nadir 9.0 seconds, or approximately 2.1 kilometers
Zenith 9.0 seconds, or approximately 2.1 kilometers
Water Vapor
Nadir 180.0 seconds, or approximately 42 kilometers
Horizontal display interval for averaged data other than full flight images
Aerosol 9.0 seconds or approximately 2.1 kilometers
Water Vapor 9.0 seconds or approximately 2.1 kilometers
Times on the images are Universal Time (UT).
For those images that span 00 UT, the dates refer to the start date of the image.
Images have annotation (letters or numbers) for certain times. The numeral annotations are
at the times associated with the dropsonde releases from the DC-8. The "A" annotations are
the Vaisala sondes launched from Andros Island during Flight 06 at 19:11 UT. The DC-8 made
three passes over Andos Island during this sonde flight. The "E" annotations are at the times
associated with dropsonde releases from the ER-2 high altitude research aircraft.
