Tests of the remote sensing spectrumradiometer DAN - 2 on atmospheric lines

摘要

Presented results of testing a developping equipment DAN-2, allowing remote define gas components in atmosphere with the big degree noiseproof factor. Determined condition of aplicability of method lying in the base of functioning (working) an equipment, on tilted atmospheric routes a length before 3 km and more in the different for dioxide nitrogen. Experimental shown that under tilted corners of flexing, forming (0-10)° from the surface of the Land it is necessary to enter an additional calibring factors , connected with the solar spectrum transformation in atmosphere. Adjustments of other sort stipulated by comer effects , it is necessary to take account into corners from 0°before 20°at orientation to optical axis of receiving telescope toward the solar disk. Determined factors for different visibility and meteoconditions : cloud, mist, fair weather. Given concrete recommendations on using an equipment DAN-2 for correct interpreting the results of measurements. For length of time from november 2002 on a may 2003 on the base of apparatuse complex DAN-2 was received near 400 experimental studies. As a source of atmospheric contamination was choose industrial object, residing in the most centre of city Tomsk electric power station GRES-2. Measurements were conducted at a different time of with different types of the atmospheric condition (fair weather, obscured cloud, hazes and mists). Made registration to concentrations a gas NO2 provided in relative units. Primary task of an ing the experimental studies was produce evaluation of potential possibilities of laboratory complex with provision for dispersion-diffusing characteristics of complex atmospheric ambience, reveal main theoretical and technical problems for the reason further modernizations testing device.
