| Summary: | 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 cm −1 spectral range with 0.4 cm −1 resolution and a radiometric uncertainty of better than 0.85 <math xmlns="http://www.w3.org/1998/Math/MathML" id="M3" display="inline" overflow="scroll" dspmath="mathml"><mrow><mi mathvariant="normal">mW</mi><mspace width="0.125em" linebreak="nobreak"/><mo>(</mo><msup><mi mathvariant="normal">m</mi><mn mathvariant="normal">2</mn></msup><mspace width="0.125em" linebreak="nobreak"/><mi mathvariant="normal">sr</mi><mspace linebreak="nobreak" width="0.125em"/><msup><mi mathvariant="normal">cm</mi><mrow><mo>-</mo><mn mathvariant="normal">1</mn></mrow></msup><msup><mo>)</mo><mrow><mo>-</mo><mn mathvariant="normal">1</mn></mrow></msup></mrow></math> <svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="91pt" height="15pt" class="svg-formula" dspmath="mathimg" md5hash="a0e86b279b28d5b2a7324eed0e7b322b"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="amt-12-619-2019-ie00001.svg" width="91pt" height="15pt" src="amt-12-619-2019-ie00001.png"/></svg:svg> . |
