PythonicDISORT - v1.2

pydisort now internally enforces Kirchoff's law of thermal radiation for the isotropic internal source (its emissivity is set to 1 - omega_arr). Consequently, emissivity no longer needs to be factored into s_poly_coeffs and subroutines.generate_s_poly_coeffs has been changed accordingly.
Streamlined code in PythonicDISORT. This should not cause any noticeable change in functionality or performance.

PythonicDISORT - v1.1

Fixed bug wherein having a layer with no scattering inbetween two scattering layers will cause miscalculations
Implemented zeroing of tiny single-scattering albedo $\omega$ values or tiny Legendre coefficients -- it will still be better for users to zero such values themselves
General improvements to documentation including a new warning that using an excessive number of streams $\text{NQuad} \gtrsim 300$ will cause some quadrature angles to be extremely glancing ($\mu \sim 0$) and the computed intensity at those angles may be inaccurate

Published by dhjx1996 10 months ago

v1.0.0 is finally out! We added subroutines to facilitate the modeling of longwave radiative transfer. In addition, we implemented almost all of DISORT's longwave radiative transfer tests (tests 6 and 7 in particular) and tested PythonicDISORT on the anisotropic Hapke BDRF.

We are now confident that PythonicDISORT matches DISORT in functionality.

PythonicDISORT - v0.9.2

Fixed bug in direct beam multilayer solver.
Changed assert-based input checks to if-statements that raise ValueError.
Added return_tau_arr argument to every output function (tau is the optical depth and tau_arr demarcates the layers in the atmosphere)
Improved and corrected documentation.
Added explanatory preamble to each PyTest.

PythonicDISORT - v0.8.0

Enabled each output function of pydisort to switch to its antiderivative by passing the argument is_antiderivative_wrt_tau = True. For example, flux_up(tau0, is_antiderivative_wrt_tau=True) - flux_up(0, is_antiderivative_wrt_tau=True) will give the integral of flux_up over $\tau \in [0, \tau_0]$.

PythonicDISORT - v0.7.0

Added a lot of documentation and comments to the code. Also, renamed a number of variables, files and functions. Changed the test points to exactly match those of DISORT (per disotest.f90) which significantly reduces the size of the repository. Fixed a few minor bugs.

PythonicDISORT - v0.6.0

We have further optimized the code to increase speed and reduce memory usage. We have improved our sparse matrix framework to better handle a large number of atmospheric layers. In this and a few other ways, the algorithm has been made more robust. The newly optimized code makes use of np.add.at which may itself have optimization flaws. Nonetheless, %timeit tests show our new code to be faster. We also made some quality of life and documentation changes.

Further optimized PythonicDISORT and removed parallelization option since parallelization will now almost never be worth the overhead. Consequently, joblib is no longer a dependency. The file structure of the algorithm (in src) also underwent significant changes.
