“Clear water” is a scale-dependent concept, so it is more likely to successfully find the “clear waters” from images with smaller scale than that with larger scale data. In this study, an optimal spectral relationships of Moderate-resolution Imaging
In this study, an atmospheric correction algorithm (improved “clear water” atmospheric correction algorithm for broad-band sensors, or “ICAB” algorithm) was constructed and tested, and the results are shown in this paper. The Rayleigh scattering con
A simple atmospheric correction algorithm (SACA) based on a “known” empirical spectral relationship at two bands of MODIS sensor has been developed as a modification to improve the MODIS ocean color products in shallow turbid waters. The analysis re
this code predicts the satellite signal from 0.25 to 4.0 microns assuming cloudless atmosphere.the main atmospheric effects (gaseous absorption by water vapor,carbon dioxyde,oxygen and ozone; cattering by molecules and aerosols) are taken into accou
A model for measuring aerosol mass concentration by an optical particle counter is presented using the conception of the average mass. In this model, to understand the meaning of the pulse height distribution of particles which is used to inverse mas
The sensitivity of Doppler wind lidar is an important parameter which affects the performance of Doppler wind lidar. Aerosol scattering ratio, atmospheric temperature, and wind speed obviously affect the measurement of Doppler wind lidar with iodine
In order to improve the inversion precision of aerosol mass concentrations based on the particle group light scattering method, the concept that particles through a laser beam are equivalent to an aggregate is proposed. A fractal model for aerosol ma
An ultraviolet (UV) Raman lidar system at 354.7 nm has been developed for accurately measuring the aerosol extinction profiles. A spectroscopic filter combining a high-spectral-resolution grating with two narrowband mirrors is used to separate the vi
Elastic lidar observations of profiles of the aerosol extinction, backscattering coefficients, and the lidar ratio have been performed in Beijing. The elastic lidar transmitts wavelengths of 532 and 355 nm. The measurement altitude can reach up to 6
The correct calibration of coefficients in the inversion model for aerosol mass concentration is the precondition of obtaining highly precise results. The concept of the fractal dimension of scattering equivalent section is presented, and the calibra
A new method is proposed based on the analysis of lidar equation which selects aerosol backscatter ratio at a reference point for short range lidar in data processing. Simulation computation and experimental comparison results show that this method i
