 Problem #1 
Using the nine output files from the previous section, determine the time variation of the emission rate using the ratio method.
 Hint 
Instead of using a simple ratio of Measured/Calculated to determine the release rate each hour, use the values already tabulated in the coefficient matrix (c2array.csv) to compute a regression of M/C using the Excel slope function.
 Solution  The hourly release rate Excel solution shown on line 22 also shows considerable overprediction.
 Problem #2 
We've found that the SVD or Cost function solutions are very sensitive to model error. We could create an ensemble mean to reduce error but this may take a more advanced level of script programming. In the last section, exercise #12, we found from the physics ensemble, that the simulation using the Beljaars turbulence (kblt=1) provided the best results. Recreate the nine output files for each emission time using this approach and compute the emission rate using SVD and cost function solutions.
 Hint  The simplest approach is to edit the script with the additional namelist variables.
 Solution  Solving the TCM shows that although the large overpredictions during the emission times are less, overall the SVD solution shows overprediction by a factoroffour compared to the original result. The cost function solution with the optimized dispersion is comparable to the original result.
