# A Fourier transform spectroradiometer for ground-based remote sensing of the atmospheric downwelling long-wave radiance

The Radiation Explorer in the Far Infrared – Prototype for Applications and Development (REFIR-PAD) is a Fourier transform spectroradiometer that has been designed to operate from both stratospheric balloon platforms and the ground. It has been successfully deployed in a stratospheric balloon flight and several ground-based campaigns from high-altitude sites, including the current installation at the Italian–French Concordia Antarctic station. The instrument is capable of operating autonomously with only a limited need of remote control and monitoring and provides a multiyear dataset of spectrally resolved atmospheric downwelling radiances, measured in the 100–1500 inline-formulacm−1 spectral range with 0.4 inline-formulacm−1 resolution and a radiometric uncertainty of better than 0.85 inline-formula $M3inlinescrollmathml\mathrm{normal mW}\phantom{\rule{0ex}{0ex}}\left({\mathrm{normal m}}^{normal 2}\phantom{\rule{0ex}{0ex}}\mathrm{normal sr}\phantom{\rule{0ex}{0ex}}{\mathrm{normal cm}}^{-normal 1}{\right)}^{-normal 1}$ 91pt15ptsvg-formulamathimga0e86b279b28d5b2a7324eed0e7b322b amt-12-619-2019-ie00001.svg91pt15ptamt-12-619-2019-ie00001.png .
