In the paper the description of the last version of code MaexPro (Marine aerosol extinction Profile) for calculation
spectral and vertical profiles of aerosol extinction coefficient α(λ), aerosol sizes distribution, area distribution, volumes
distribution, modes aerosol extinction spectra is submitted.
Code MaexPro is a computer program under constant development to estimate of EO systems signal power at a location
place in which a fetch is key entrance parameter. The program carries out calculation α(λ), as functions of atmospheric
effects using standard meteorological parameters, aerosol microphysical structure, a spectral band and a height of the
sensor location. Spectral behavior α(λ) can be submitted as graphically, and as tables. Commands overplot for
superposition or change of figures; profiles extrapolation; a lens; all kinds of possible copying; the data presentation,
convenient for an input in code MODTRAN, and etc. are stipulated.
The code MaexPro is a completely mouse-driven PC Windows program with a user-friendly interface. Calculation time
of spectral and vertical profiles of α(λ) depends on the necessary wave length resolution, radius of aerosol particles and
the location place height, and does not exceed tens seconds for each new meteorological condition. Other calculations
characteristics, such as aerosol sizes distribution, area distribution, volumes distribution, modes aerosol extinction
spectra, are performed in a few seconds.
