The output file contains (for all 36 geometries and 5 output levels) thebaseline intensities, baseline Analytic weighting functions (AJ1, AJ2 etc.),and the corresponding finite difference weighting functions (FD1, FD2 etc ).The integrated output (actinic and regular fluxes) are output for all SZAs andall 5 output levels.The second part is an intensity + COLUMN and surface albedo weighting functioncalculation.There are 2 NORMALIZED column weighting functions:1. w.r.t. total trace gas absorption optical depth of the wholeatmosphere.2 w.r.t. total aerosol optical depth in bottom 6 layers.There is 1 NORMALIZED surface weighting function:1. w.r.t. Lambertian albedo.We are using the in/outgoing single-scatter correction with delta-M scaling(this is a standard default, and the most accurate calculation).The first call is the baseline calculation of intensity, 2 column Jacobians,and 1 Surface Jacobian. The 3 threads are designed to test Jacobians byfinite differencing. They are:Thread 5: Finite difference, perturb Lambertian albedo.Thread 6: Finite difference, perturb total molecular absorption opticaldepth.Thread 7: Finite difference, perturb total aerosol optical depth.The output file contains (for all 36 geometries and 5 output levels) thebaseline intensities, baseline Analytic weighting functions (AJ1, AJ2 etc.),and the corresponding finite difference weighting functions (FD1, FD2 etc ).The integrated output (actinic and regular fluxes) are output for all SZAs andall 5 output levels.Thermal Tester--------------Master programExecutableOutput file: 2p6_thermal_tester.f90: s2p6_thermal_tester.exe: results_thermal_tester.allThis is an intensity-only calculation with 6 threads:Thread 1: Thermal only, with scattering, + delta-M, Lambertian.Thread 2: Thermal transmittance only.Thread 3: Crossover Ingoing-only Single-scatter correction + delta-M, Lamb.Thread 4: Crossover In/Outgoing Single-scatter correction + delta-M, Lamb.Thread 5: Crossover In/Outgoing Single-scatter correction + delta-M, BRDF1.Thread 6: Crossover In/Outgoing Single-scatter correction + delta-M, BRDF3.The output file contains intensities for all 6 of these threads, all 36100
