The toxicity of ultraviolet radiation in wavelength range 100-280 nm (UV-C) is well documented. UV-C irradiation can cause skin cancer, premature aging, visual problems and blindness. Prolonged exposure to UV radiation can kill both plants and animals, including entire forests. There are numerous assertions in the medical, public health, and geoscience literature that no UV-C reaches Earth's surface, despite several studies to the contrary including one in 2007 by NASA. Naysayers blame technical problems such as stray light. Low-level UV-C measurements are difficult, if not nearly impossible, when using low integration values in the CCD Imaging Spectral Radiometers. This is due to the instrument's internal and external atmospheric stray light issues, issues which even occur during calibration procedures that employ heated filament or gas-filled lamps. To obviate these inherent problems, one of us (RDH) designed, engineered, and constructed a Double Monochromator utilized in conjunction with the ILT950UV Spectral Radiometer operating in the raw data mode. Each of the initial measurements of solar irradiance displayed evidence of UV-C arriving at Earth's surface, not high in the mountains, but just 176 meters above sea-level. These data were taken in the raw data mode, corrected for prism loss, with instrument noise, i.e. machine errors, subtracted. The non-zero value for relative spectral irradiance clearly shows the existence of UV-C at Earth's surface, in the range 250-300 nm, even when measured under less than optimum atmospheric conditions. Research and development continue. We must know with certainty the condition of the stratospheric ozone layer that shields surface life from solar UV-C. Covert geoengineering atmospheric particulate pollution, in combination with industrial pollution of the atmosphere, is killing Earth's stratospheric ozone layer. If unabated, it will sound the death knell for much of life on Earth.

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.
