mxavrg - sinotec2/CAMx_utility GitHub Wiki

###Objective
Obtaining the maximum of CAMx simulation result, among the time and 3D spatial dimensions。　
In the spatial dimension, the program will take the 98% maximum accordance to the regulation. On the other hand, the maximum of spatial will not take 98%, and is simply the 100% maximum.

Usage

mxavrg FILE    

Result files

The result of mxavrgexcution will get two files: the first is FILEM, also a CAMx(UAM) formatted file，
and FILEM98.dat a print-out of each species maximum, and the maximum occurrence time.

Parallelization

The current version of [mavrg.f] (https://github.com/sinotec2/CAMx_utility/blob/master/mavrg.f) has been edited in parallelized formulation.

Note

####1.About the length of data time
The program will calculate the 98% of all time-length and determine which value is correct the the 98% maximum. If the time-length is not greater than 100, such as daily mean of a month, the program will get the 100% maximum. As the data length is longer, the value of 98% maximum will lowering.
####2.About the spatial domain
The program will not determine whether the grid location is in the ocean or on the land. Users are suggested to run another program of land_avrg.f, after that, then excute mxavrg again.
