Scattering Base

Dr. Patrick Stegmann, JCSDA CRTM team

Requirements

To compile the package, gfortran is currently required. The recommended version is 9.3.0 .

Setup

Folder Structure

The package currently consists of 4 folders:

1. SizeGrid: the code to compute the quadrature points for the integration over the PSD of a single effective radius.
2. bhmie: Bohren and Huffman Lorenz-Mie code, modified for this project.
3. bulk: code to compute bulk scattering properties from the single-scattering data using the trapezoidal rule.
4. scratch: working directory where the database is created.

Compiling Executables

To compile the executables you need to enter every folder of this project and compile them manually. Enter each directory except scratch and simply type make.

Linking Executables

To link the executables in the working directory, enter scratch and run the linking script:

cd scratch/
./link_executables.sh

Running a calculation

To run the calculations, enter the working directory scratch and run the calculation script run_calculations.sh:

cd scratch/
./run_calculations.sh

This will create the ./database/ folder, which is a very large folder containing subdirectories for every frequency, effective radius and quadrature point specified in run_calculations.sh. It contains the bulk scattering properties for every frequency and effective radius at the corresponding folder level.
