DOI](https://zenodo.org/badge/DOI/10.5281/zenodo.213475.svg)](https://doi.org/10.5281/zenodo.213475)\n![Actions Status](https://github.com/space-physics/lowtran/workflows/ci/badge.svg)\n[![PyPi Download stats](http://pepy.tech/badge/lowtran)](http://pepy.tech/project/lowtran)\n\nLOWTRAN7 atmospheric absorption extinction model.\nUpdated to be platform independent and easily accessible from Python and\n[Matlab](#matlab).\n\nThe main LOWTRAN program is accessible from Python by using direct memory transfers instead of the cumbersome and error-prone process of writing/reading text files.\n`xarray.Dataset` high-performance, simple N-D array data is passed out, with appropriate metadata.\n\n## Gallery\n\nSee below for how to make these examples.\n\n![Lowtran7 absorption](./gfx/lowtran.png)\n\n## Install\n\nLowtran requires a Fortran compiler and CMake.\nWe use `f2py` (part of `numpy`) to seamlessly use Fortran libraries from Python by special compilation of the Fortran library with auto-generated shim code.\nFor Python 3.12, make sure to install setuptools using pip, i.e., `pip install setuptools` and make sure meson is available on the system.\n\nIf a Fortran compiler is not already installed, install Gfortran:\n\n* Linux: `apt install gfortran`\n* Mac: `brew install gcc`\n* Windows: Windows Subsystem for Linux\n\nInstall Python Lowtran code\n\n```sh\npip install -e .\n```\n\n## Examples\n\nIn these examples, optionally write to HDF5 with the `-o` option.\n\nWe present Python [examples](./example) of:\n\n* ground-to-space transmittance: TransmittanceGround2Space.py\n\n  ![Lowtran Transmission](./doc/txgnd2space.png)\n* sun-to-observer scattered radiance (why the sky is blue): ScatterRadiance.py\n\n  ![Lowtran Scatter Radiance](./gfx/whyskyisblue.png)\n* sun-to-observer irradiance: SolarIrradiance.py\n\n  ![Lowtran Solar Irradiance](./gfx/irradiance.png)\n* observer-to-observer solar single-scattering solar radiance (up-going) with custom Pressure, Temperature and partial pressure for 12 species: UserDataHorizontalRadiance.py\n  ![Lowtran Solar Irradiance](./gfx/thermalradiance.png)\n* observer-to-observer transmittance with custom Pressure, Temperature and partial pressure for 12 species: UserDataHorizontalTransmittance.py\n* observer-to-observer transmittance: HorizontalTransmittance.py\n\n  ![Lowtran Horizontal Path transmittance](./gfx/horizcompare.png)\n\n### Matlab\n\nMatlab users can seamlessly access Python modules, as demonstrated in\n[RunLowtran.m](./RunLowtran.m).\n\nHere's what's you'll need:\n\n1. [Setup Python \u0026harr; Matlab interface](https://www.scivision.dev/matlab-python-user-module-import/).\n2. Install Lowtran in Python as at the top of this Readme.\n3. From Matlab, verify everything is working by:\n\n   ```matlab\n   runtests('lowtran')\n   ```\n\n## Notes\n\nLOWTRAN7\n[User manual](http://www.dtic.mil/dtic/tr/fulltext/u2/a206773.pdf)\nRefer to this to understand what parameters are set to default.\nCurrently I don't have any aerosols enabled for example, though it's possible to add them into the code.\n\nRight now a lot of configuration features aren't implemented, please request those you want.\n\n### Reference\n\n* Original 1994 Lowtran7 [Code](http://www1.ncdc.noaa.gov/pub/data/software/lowtran/)\n* `LOWFIL` program in reference/lowtran7.10.f was not connected as we had previously implemented a filter function directly in  Python.\n* `LOWSCAN` spectral sampling (scanning) program in `reference/lowtran7.13.f` was not connected as we had no need for coarser spectral resolution.\n","funding_links":["https://github.com/sponsors/scivision","https://ko-fi.com/scivision"],"readme_doi_urls":["https://doi.org/10.5281/zenodo.213475"],"works":{"https://doi.org/10.5281/zenodo.213475":null},"citation_counts":{},"total_citations":0,"keywords_from_contributors":[],"project_url":"https://ost.ecosyste.ms/api/v1/projects/760","html_url":"https://ost.ecosyste.ms/projects/760"}
