Tests of installation

Test of libRadtran installation

libRadtran must be installed according the instructions given at libRadtran web site .

In addition libradtranpy requires that one environnement variable LIBRADTRANDIR must be set to libRadtran installation path, under which one have each of these directories:

• /bin

• /share/libRadtran/data

• /include

• /lib and

• /share

from libRadtran installation directory.

example:

>> tree -L 1 libRadtran

libRadtran

├── bin

├── include

├── lib

├── libRadtran-2.0.5

└── share

and the inside the share directory the data/ directory must be available:

>> cd libRadTran

/> tree -L 2 share/

share/

└── libRadtran

├── GUI

├── data

├── doc

└── examples

and inside the data/ directory you must have libRadtran data installed as folow

>> tree -L 1 data

data

├── aerosol

├── albedo

├── altitude

├── atmmod

├── correlated_k

├── crs

├── filter

├── ic

├── nca_lookup

├── scripts

├── solar_flux

└── wc

libradtranpy tests

After libRadtran and libradtranpy installation (using the command pip install -e '.[dev]'), a simple test to check if libradtran is installed correctly runs:

# call unit tests

>> python -m unittest tests/libradtranpy/*.py

or in verbose mode:

# call unit tests in verbose mode

>> python -m unittest -v tests/libradtranpy/*.py

it checks: * the existence of the environnement variable LIBRADTRANDIR point to the libradtran installation top directory * the existence of the bin directory and the executable uvspec * the existence of the share/libRadtran/data directory which hold all the internal data that `libRadtran`requires for its execution. * the execution of a libradtran simulation works well returning some data.
