Clarification of W126 Daily Index Computation and Minor Code Corrections

Christian Hogrefe, U.S. Environmental Protection Agency
Type of update: documentation, minor bug fix
Release Version/Date: CMAQv5.4
Description: Updated the README and inline code documentation to clarify that the W126 option computes the W126 daily index value as a weighted average of ozone concentrations between 8am & 7pm and that these daily index values are only an intermediate step in computing the W126 metric for secondary ozone standard analyses. These daily index values can then be used to calculate annual W126 values for the secondary ozone standard by using different tools to first compute 3-month sums of daily W126 index values and then determine the consecutive three month period with the largest 3-month sum of daily W126 values. There were also minor code corrections that fixed two issues that may have caused problems for certain compilers in debug mode but did not affect the results of the computations in the tests conducted.
Significance and Impact: No impact on results for the cases tested.
