我们根据与帝国理工学院对流层机载的可见光和红外辐射连续体吸收以及大气相关性 (CAVIAR) 项目的飞行活动中收集的现场数据，提出了 24μm 和 120μm (85–420cm−1) 之间的远红外 (far-IR) 纯旋转波段中的外国拓宽水汽连续体的新推导。机载大气测量设施 (FAAM) BAe-146 研究飞机上的傅立叶变换光谱仪 (TAFTS) 远红外光谱辐射计仪器；并将这个新的推导与最近在该光谱带的文献中发表的推导进行比较。这个新数据集验证了当前 300 cm−1 以上的 Mlawer–Tobin-Clough–Kneizys–Davies (MT-CKD) 2.5 模型参数化，但表明需要将 300 cm−1 以下的参数化加强，在 100 cm−1 时增强高达 50%。在多个飞行高度记录的数据允许在大范围的柱状水蒸气环境中进行测量，从而大大提高了该分析对连续体强度的灵敏度。
We present a new derivation of the foreign-broadened water vapour continuum in the far-infrared (far-IR) pure rotation band between 24 μm and 120 μm (85–420 cm−1) from field data collected in flight campaigns of the Continuum Absorption by Visible and IR radiation and Atmospheric Relevance (CAVIAR) project with Imperial College's Tropospheric Airborne Fourier Transform Spectrometer (TAFTS) far-IR spectro-radiometer instrument onboard the Facility for Airborne Atmospheric Measurement (FAAM) BAe-146 research aircraft; and compare this new derivation with those recently published in the literature in this spectral band. This new dataset validates the current Mlawer–Tobin-Clough–Kneizys–Davies (MT-CKD) 2.5 model parametrization above 300 cm−1, but indicates the need to strengthen the parametrization below 300 cm−1, by up to 50 per cent at 100 cm−1. Data recorded at a number of flight altitudes have allowed measurements within a wide range of column water vapour environments, greatly increasing the sensitivity of this analysis to the continuum strength.
