Why do you know so much random information T_T You make me doubt myself. Further example in your response:
"Satellite based instruments can be used to detect ozone concentration in the stratosphere.
Following calibration issues with the last Total Ozone Mapping Spectrometer (TOMS) unit in orbit, they were replaced in 2007 by the Ozone Mapping Instrument operated from the NASA Aura. Satellite based instruments map differences in incoming solar energy and backscattered UV light across earth. In doing so, these instruments highlight areas if weakness in the ozone layer by noting the failure of the ozone layer to absorb UV light.
The Donson Ozone Spectrophotometer is a ground based izone concentration detection system that is
less precise than satellite based models and thus
primarily used for corroborating satellite data. It works by measuring the amount if one wavelength of UVA radiation reaching earth, which does not have the energy to photolysise ozone and thus is not absorbed by the ozone layer, against one wavelength of UVB radiation, which does have the energy to photolysise ozone and thus will reach earth in an amount which is
directly proportional to ozone concentration in the stratosphere."
Bold: never heard of such things.
Am i going to get b5
My understanding is basically Satellite-based TOMS: Measure ozone concentration at various altitudes and geographical locations (no idea how; where did you learn this?), resulting in an ozone concentration map
Ground-based spectrophotometers: In a vertical column, measures intensity of a wavelength characteristically absorbed by UV-B and UV-C, which is then compared to a different wavelength to measure total-column ozone in Dobsin units DU
Red: Do you mean inversely proportional?
