Important notice: multi-molecule calculations will intentionally crash if broadening coefficients are not available for all the species [according to Radis "Better Crash Than Hide" policy]. See #653 for future workarounds

⚙️User-interface

🏃 Performance improvement

  • Calculation with Vaex (beforehand, only loading of database was performed with Vaex) : #576, #580

To use Vaex

  • Cuda driver by @dcmvdbekerom in https://github.com/radis/radis/pull/604 : gets rid of cupy and CUDA toolkit dependencies.
    In layman terms, this means you don't need to install excessive software just to make use of GPU capabilities. "GPU for all" !

An example to compare CPU and GPU codes:

from radis import SpectrumFactory
fixed_conditions = {
    "path_length": 1,
    "wmin": 2000,
    "wmax": 3000,
    "pressure": 0.1,
    "wstep": 0.001,
    "mole_fraction": 0.01, 
    "verbose":0}
Tgas = 1000
sf = SpectrumFactory(
    **fixed_conditions,
    broadening_method="fft",
    molecule='CO2'
)
sf.fetch_databank("hitemp")

s1_gpu = sf.eq_spectrum_gpu(
    Tgas=Tgas,  # K
    backend="gpu-cuda",  # runs on GPU
    diluent={'air':0.99})
s1_cpu = sf.eq_spectrum(    
    Tgas=Tgas,  # K
    diluent={'air':0.99}
)

integral_GPU = s1_gpu.get_integral("absorbance")
integral_CPU = s1_cpu.get_integral("absorbance")

Last major release of 2021 with extreme performance improvements when computing large range spectra. And by large range, we mean full-range, i.e. 0 - 30,000 cm-1 !

See PR https://github.com/radis/radis/pull/400

Changes since 0.10.3 (September 2021) :

🔬 (Physics) Features

  • #394 : ExoMol works for isotopes
  • #394 : add isotopic abundance in ExoMol calculations [Important ! calculations other than main isotopologue were not valid for ExoMol in 0.10.3 ]
  • #394 : add default molar_mass, abundances & full-isotope name for all 85 ExoMol species that are not present in HITRAN
  • #394 : when not available abundances of molecules are computed from a simple model based on isotopic terrestrial abundance of elements (scripts are available in test_molecule_lists)
  • #398 re-add broadening for ExoMol molecules

⚙️User-interface

  • #394 : auto-fetch the full molecule & isotopes list from ExoMol website
  • #394 simplify calc_spectrum waverange input : default is now to use wmin, wmax (unit-aware), instead of wavenum_min, wavenum_max or wavelength_min, wavelength_max (old parameters still work)
  • 399 bridge to/from Specutils
spectrum = s.to_specutils()
...
from radis import Spectrum
Spectrum.from_specutils(spectrum)
  • #399 option to return SpectrumFactory used in a calc_spectrum computation
s, sf = calc_spectrum(.... ,return_factory=True
sf.df1     # lines used
  • #398 add fetch_hitran() which downloads all lines/isotopes of HITRAN database (Vaex compatible). It is included in calc_spectrum and SpectrumFactory.fetch_databank by default.
calc_spectrum(..., databank=("hitran", "full"))   # predownload full database & isotopes (once for all)
calc_spectrum(..., databank=("hitran", "range"))   # download only the required the range & isotope

  • #254

🏃 Performance improvement

  • ⭐ #398 make vaex the default memory-mapping-engine for radis (Spyder IDE-users: you may want to deactivate this until https://github.com/spyder-ide/spyder/issues/16183 is fixed. There is a new key in the config file for that!)
  • ⭐ #398 only load required columns by default (makes it 8-20x faster to load databases)

Example : full HITEMP-CO2 database (0 - 30,000 cm-1 loaded in 5s instead of 80 !)

  • #394 download HITRAN full-range makes HITRAN calculations faster (no more download after the first time)
  • ⭐ #386 #388 make it possible to compute full-range spectra : RADIS automatically switches to a sparse-wavenumber implementation of the DLM/DIT algorithm, based on a scarcity criterion Ngridpoints/Nlines > 1

0.10.0

(see Pull request and code changes here)

4th release of RADIS in 2021, and the largest so far !

New physics with ExoMol support, by-default truncations to account for subLorentzian behaviors, custom abundances for non-terrestrial atmospheres. Major improvements in performances (reduced memory consumption, faster database loading, up to 10x faster small CPU spectra, large range spectra are 2-30x faster, 3500x faster nonequilibrium partition functions). A few handy features for post-processing (custom plotting themes, ruler tool) or for the calculations (automatic wavenumber grid, fitting methods, new profiler, new choice of truncation & effect of neighbour lines), and even a new method to automatically cite the papers that contributed to your calculation ! 🏃

And also, lot's of new Examples of what can be done with RADIS :

  • #212 new configuration file format : ~radis.json replaces ~/.radis. Will allow to use global parameters (for plots, etc.). Auto-conversion of your existing files by @anandxkumar !
  • #229 reduce warning/error threshold of too-few-gridpoints-per-line from 5/2 to 3/1
  • #201 RADIS works for non-HITRAN molecules (they're not implemented, but you can define your own)

🏃 Performance improvement

  • #227 CO2 3-T Treanor calculations up to 5x faster when calling non_eq_spectrum a 2nd time
  • #193 #227 fetching of Evib and Erot about ~30% faster for CO2 Treanor, and CO.
  • #206 lazy-loading feature by @gugzy when working with a SpecDatabase (i.e., a folder of spectra) : only load them on demand (when using SpecDatabase.get(Tgas=.., etc.)). Setting up the database is instantaneous, and generate a summary csv file showing all calculation/experimental conditions !
  • #220 Apply_slit is now 10x faster thanks to @CorentinGrimaldi

🐛 Bug fixes

  • #81 #214 #217 fix a wavelength range mismatch
  • #203 fix direct HITEMP download for nonequilibrium calculations (CO)
  • #202 fixed export_lines parameter not working in calc_spectrum
  • #111 #191 improve error message with unlabelled CO2 lines of HITEMP, and suggest how to fix it, by @mverleg
  • #78 #80 @gagan-aryan fixed errors with missing configuration file parameters,

📝 Documentation

  • #225 add more equations in function docstrings, automatically generated from Python code with pytexit
  • #221 docs improvements
  • #216 fix rendering of radis flow chart by @anandxkumar
  • #209 mention HAPI when using Astroquery
  • #205 add Sphinx gallery examples (we still need more of them : #136 is open!)
  • #207 improve Contributing guide

radis - 0.9.28

0.9.28

2nd release of RADIS in 2021
Changes since 0.9.27 (Jan 2021) :

🔬 (Physics) Features

  • #194 automatic download of HITEMP database 🎉 (except CO2 and H2O for the moment)
from astropy import units as u
from radis import calc_spectrum
calc_spectrum(
    wavenum_min=1500 / u.cm,
    wavenum_max=2400 / u.cm,
    molecule="CO",
    Tgas=3000,
    pressure=1.01325*u.bar,
    databank="hitemp",  # fetch directly
    wstep=0.003,  # accuracy
).plot()
  • #186 #200 : better handling of coarse spectral grids

⚙️User-interface

  • #194 creates a ~/.radisdb folder for local HDF5 databases automatically generated by RADIS. These files are registered in the ~/.radis config file.
  • #194 also includes direct loading of HDF5 files (for instance for future ExoMol support)
  • #183 add cutoff as calc_spectrum option
  • Spectrum.get() returns with the Spectrum calculation wunit (cm-1 or nm), not always nm by default as before (will be more straightforward wavenumber people !)
  • add radis.spectrum.utils.has_nan util function to test spectra
  • export_lines=False by default. Saves space, but no LineSurvey by default.

🏃 Performance improvement

  • #185 faster rejection of irrelevant files (with metadata implementation), improves loading time for databases with large number of small files (typically CDSD-4000)
  • #164 prevent Memory Errors
  • #192 Improve computation performance by orders of magnitude when computing line-of-sight with hundreds of slabs

🐛 Bug fixes

  • #182
  • #186

📝 Documentation

  • lots of tiny doc improvements #178
  • reference https://radis.app in the GitHub readme.

🏁 Reliability / Tests

  • #194 downloads the HITEMP OH database with fetch_hitemp (small enough - 900 kb - so we don't burn trees by doing that!). Can be used by other tests later.

🏗️ Refactor / change in architecture

Cleaner code :

  • #187 deprecate CPU-parallel code
  • #198 deprecate old database loading methods
  • #171

Not fixed yet in 0.9.28 :

  • #78 and #80 (NOT DONE YET)
