Abstract

In this paper we report on engineering of the automated ground-basedsystem for the measurement and control of meteoparameters of the atmosphere. Improvement of the existing hardware complexes and invention of the new automated gages on modern element base is the most perspective direction in meteorological instrument making.

Applying the considered gages it is possible to receive the following characteristics of controlled meteoobject in real time: height and temperature of the lower bound of overcast, water content, water stock and some other characteristics of clouds; temperature, pressure, humidity of air and parameters of a wind in a ground layer of the atmosphere; optical thickness of the atmosphere; coefficients of blackness of clouds of various form; assessment of transparency of the atmosphere; optical density of translucent clouds; density of a ground aerosol and sizes of its particles.

Measuring systems are united spatially and functionally in the NALRK general complex. This complex includes the following measuring systems:

 - the scanning infrared installation intended for determination of the main meteoparameters of the atmosphere and clouds; works in the spectral range of 8-14 microns;
 - infrared pulse lidar for determination of height of the lower bound of clouds; the maximum range of action to 7,5 km works at wavelength ? = 1,06 microns;
 - lidar with the linear frequency modulation (LFM) for measurement of an aerosol in a ground layer; sounding height to 1 km works at wavelength ? = 0,532 microns;
 - the watching infrared installation for determination of optical density and thickness of translucent clouds, and also coefficient of transparency of the atmosphere; working spectral range is from 2,1 to 2,4 microns, the tracking mode the automatic;
 - the laser measuring instrument of the sizes, concentration and speeds of particles for determination of parameters of a ground aerosol; the measured range ot1 to 300 microns;
 - a meteorological station for determination of the main meteoparameters of a ground layer.

Use of the ground-based automated lidar-radiometric complexwithresults of measurement will be expedient in TsAO of Roshydromet, RCfor Earth Operative Monitoring of Federal Space Agency, MNPO «Spektr», GPU «Mosekomonitoring», IFA n.a. A.M. Obukhov of the Russian Academy of Sciences, GGO n.a A.I. Voeykov and in other organizations connected with research and forecasting of a meteorological situation, and also with environmental monitoring in any region.
