Abstract. This paper reports on a third generation rotating shadowband spectroradiometer (RSS) used to measure global and diffuse horizontal plus direct normal irradiances and transmissions at 1002 wavelengths between 360 and 1070 nm. The prism-dispersed spectral data are from the ARM Southern Great Plains site in north central Oklahoma (36.605 N, 97.486 W) and cover dates between August 2009 and February 2014. The refurbished RSS isolates the detector in a vacuum chamber with pressures near 10⁻⁷ torr. This prevents the deposition of outgassed vapors from the interior of the spectrometer shell on the cooled detector that affected the operation of the first commercial RSS. Methods for (1) ensuring the correct wavelength registration of the data and (2) deriving extraterrestrial responses over the entire spectrum, including throughout strong water vapor and oxygen bands, are described. The resulting data produced are archived as ARM data records and include cloud-screened aerosol optical depths as well as spectral irradiances and solar transmissions for all three solar components.

使用翻新的旋转影带光谱仪 (RSS) 进行中等光谱分辨率太阳辐照度测量、气溶胶光学深度和 360 至 1070 nm 的太阳透射率

摘要。本文报告了第三代旋转阴影带光谱仪 (RSS)，用于测量 360 至 1070 nm 之间的 1002 个波长的全局和漫射水平和直接法向辐照度和透射率。棱镜色散光谱数据来自俄克拉荷马州中北部的 ARM 南部大平原站点（36.605 N，97.486 W），涵盖日期为 2009 年 8 月至 2014 年 2 月。翻新后的 RSS 将检测器隔离在真空室中，压力接近 10 ^{- 7}托。这可以防止来自光谱仪外壳内部的脱气蒸汽沉积在冷却检测器上，从而影响第一个商用 RSS 的运行。描述了用于 (1) 确保数据的正确波长注册和 (2) 在整个光谱上（包括整个强水蒸气和氧气带）推导地外响应的方法。生成的数据被存档为 ARM 数据记录，包括所有三个太阳能组件的云筛选气溶胶光学深度以及光谱辐照度和太阳透射率。
