Abstract

The invention discloses an airspace particulate matter vertical distribution monitoring method based on laser radar. The method comprises the steps of 1, conducting signal detection on airspace particulate matter and conducting data acquisition to obtain data X1; 2, measuring the cloud layer height of airspace to obtain data Y; 3, conducting continuous measurement on aerosol, air pollutant and vapor to obtain data X2; 4, conducting continuous measurement on the concentration of air pollutant to obtain data X3; 5, executing step 1, 3 and 4 based on the time interval of T0 to obtain time data T. The cloud layer height of airspace is measured with a laser ceilometer, measurement time serves as the ordinate and abscissa of detection, the concentration and distribution points of airspace particulate matter are monitored through back scattering laser radar, differential absorption radar and Raman-Mie scattering laser radar, and future airspace particulate matter is predicted by means of time period.

Description

technical field [0001] The invention belongs to the technical field of particulate matter monitoring in atmospheric space, in particular to a method for monitoring the vertical distribution of particulate matter in atmospheric space based on laser radar. Background technique [0002] With the advancement of my country's economic development and urbanization process, low-visibility weather has become an important environmental problem faced by many cities in China, and haze has also been upgraded from the original weather state to a pollution phenomenon. At present, the observation of haze mainly relies on ground observation sites and optical remote sensing to provide air quality and haze pollution range, while detection of the vertical distribution of atmospheric aerosols in haze days is relatively rare. The "Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO)" satellite launched by the National Aeronautics and Space Administration (NASA) and the Fre...
