Abstract The Spectral Physics Environment for Advanced Remote Sensing (SPEARS)
application programming interface (API) is a Python-based, line-by-line, local thermal …

Abstract The HITRAN Application Programming Interface (HAPI) is presented. HAPI is a free
Python library, which extends the capabilities of the HITRANonline interface (www. hitran …

We present the kspectrum, scientific code that produces high-resolution synthetic absorption
spectra from public molecular transition parameters databases. This code was originally …

Accurate modeling of wavelength-integrated radiative quantities, eg integrated over a
spectral band or an instrument channel response function, requires computations for a large …

PySpecKit is a Python spectroscopic analysis and reduction toolkit meant to be generally
applicable to optical, infrared, and radio spectra. It is capable of reading FITS-standard and …

SpectraPlot is a web-based application for simulating spectra of atomic and molecular
gases. At the time this manuscript was written, SpectraPlot consisted of four primary tools for …

I present a fast Python tool, SpectRes, for carrying out the resampling of spectral flux
densities and their associated uncertainties onto different wavelength grids. The function …

In the thermal spectral range, there are millions of individual absorption lines of water vapor,
CO2, and other trace gases. Radiative transfer calculations of wavelength-integrated …

With the increasing use of satellite and ground-based high-spectral-resolution (HSR)
measurements for weather and climate applications, accurate and efficient radiative transfer …

We describe the lookup table approach that is used to store pre-calculated absorption data
in the radiative transfer model ARTS. The table stores absorption cross sections as a …
