ALMA Titan Emission Angles
收藏资源简介:
Emission angles for radiative transfer modeling (NEMESIS, see Irwin et al., 2008) of ALMA data. Files correspond to retrieved temperature profiles found in 'ALMA Titan Temperature Retrievals' (Thelen et al., 2017). Each file contains emission angles for the matching temperature profile obtained by modeling CO lines from 2012, 2013, 2014, or 2015. Files are denoted by region: disk-averaged (DA) or north (N), center (C), and south (S). Each file contains the radius of each annulus (km), the tangent altitude (x-2575 km) where available (km), the emission angle (deg), and the weighting of that emission angle in the radiative transfer model; weightings add to unity. Thelen et al., 2017.
本数据集为ALMA(阿塔卡马大型毫米/亚毫米波阵列)数据的辐射传输建模(采用NEMESIS模型,参见Irwin等,2008)所需的发射角。各文件对应《ALMA土卫六温度反演》(Thelen等,2017)中收录的反演温度廓线。每份文件均包含匹配温度廓线对应的发射角,该廓线通过对2012、2013、2014或2015年的一氧化碳(CO)谱线进行建模得到。文件按观测区域命名:盘面平均(DA)、北极(N)、中心(C)以及南极(S)。每份文件包含以下信息:每个环形区域的半径(单位:千米)、可用的切向高度(以x-2575 km形式标注,单位:千米)、发射角(单位:度),以及该发射角在辐射传输模型中的权重;所有权重之和为1。Thelen等,2017。
