Aims: Concerted efforts are made to deceive the public into falsely believing the jet-emplaced tropospheric aerosol trails, called chemtrails by some, are harmless ice-crystal contrails from aircraft engine exhaust-moisture. Our objective is to use radiometric measurements in the range 250-300 nm to show that a typical chemtrail is not a contrail, and to generalize that finding with additional data. 

Methods: We utilized International Light Technologies ILT950UV Spectral Radiometer mounted on a Meade LXD55 auto guider telescope tripod and mount assembly.

Results: Radiometric solar irradiance spectra data that included the transit of a typical tropospheric aerosol trail between radiometer-sensor and the solar disc showed significant absorption during    the transit period. The during-transit absorption is wholly inconsistent with the almost negligible adsorption by ice, but is wholly consistent with absorption by aerosolize particulates, including coal fly ash. This result is consistent with other aerosol-trail physical phenomena observations.

Conclusions: The public and the scientific community have been systematically deceived into falsely believing that the pervasive, jet-sprayed ‘chemtrails’ are harmless ice-crystal contrails. We have presented radiometric measurements which unambiguously prove the falsity of that characterization for one specific, but typical instance. We show in a more general framework that the physical manifestations of the aerial trails are inconsistent with ice-crystal contrails, but entirely consistent with aerosol particulate trails. We describe potential reasons for the deception, and cite the extremely adverse consequences of the aerial particulate spraying on human and environmental health. For the sake of life on Earth, the modification of the natural environment by aerial particulate spraying and other methodologies must immediately and permanently end.
