kmavrg - sinotec2/CAMx_utility GitHub Wiki

Objective

CAMx model outputs are generally in three-dimensional structures, but the satellite observations are in a two-dimensional structure, which results are averaged in the vertical direction. So for comparison purpose, one need to take the averages in the vertical direction.

Usage

    kmavrg FILE

File manipulation

kmavrg execution result will produce a file, which name is FILEL, is also CAMx (UAM) file format.

Parallelization

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

Note

File suffix confusion

The suffixes of results from kmavrg and slim are both fileL, which are in two-dimensional data structures also just a single layer of data. But quite different in the meaning of the two programs. The former is a vertical average, and the latter is to take the ground layer data. Fortunately, the satellite data is in a large range manner, also the resolution is low, generally D2(.grd01 in suffixes) as the benchmark. While the latter was a small range of high-resolution, generally D4(with .grd02 in suffixes) as a benchmark. So it does not cause serious confusion.
