Obtain the convolved OD or transmittance data for a single layer

Dear LBLRTM Team,​
Hello! Currently, I am conducting the LBLRTM testing. I have input the atmospheric profile data of 37 - layer height, and LBL can output the atmospheric optical depth at a single frequency. However, I expect to obtain the total optical depth of each individual layer, such as the total optical depth of the first layer to the thirty - seventh layer respectively.​
By analyzing the source code, it is found that LBL seems to output the total atmospheric transmittance in the FLT_OUT file. This transmittance is the result of the convolution operation between the single - frequency transmittance and the spectral response function provided by the user.​
Based on this, I have conceived a method to calculate the total optical depth (OD) of different layers: split the input file 37 times, perform LBL simulations by setting different satellite altitudes (starting from the bottom of the atmosphere), so as to obtain the total transmittance at different altitudes. Then, convert the transmittance to OD using the exponential relationship and obtain the OD data of each layer through addition and subtraction operations.​
Here, I would like to consult your team whether this method is reasonable. If not, do you have any other methods to achieve my goal of obtaining the single - layer convolved optical depth (i.e., an equivalent optical depth corresponding to each layer height)?​
Thank you very much for taking the time to read my question. I am looking forward to your reply!
