为了改进热层密度模拟，以供研究和业务之用，已编制了新的太阳指数。在11个新的和4个遗留的指数和代理中，我们选择了3个（F10.7, S10.7和M10.7）用于新的JB2006经验热层密度模型。在这项工作中，我们报告了这些太阳辐照度指数的发展。描述了它们的使用原理、定义和特征，包括IS 21348:2007光谱分类和子分类、波长范围、太阳源温度区域、太阳源特征、单位光学深度地面大气吸收的高度区域和最大能量吸收区域的地面大气热过程。我们还总结了每个太阳指数用于观测太阳发射的设施和仪器、数据存在的时间框架、测量节奏、数据延迟以及研究和操作的可用性。新的太阳指数提供了预测，以及实时和历史时间框架（http://SpaceWx.com JB2006快速链接）。我们描述了预测方法，将结果与活跃和安静太阳条件的实际数据进行了比较，并比较了f10.7预测与传统HASDM和NOAA SWPC预测的改进。
New solar indices have been developed to improve thermospheric density modeling for research and operational purposes. Out of 11 new and 4 legacy indices and proxies, we have selected 3 (F10.7, S10.7, and M10.7) for use in the new JB2006 empirical thermospheric density model. In this work, we report on the development of these solar irradiance indices. The rationale for their use, their definitions, and their characteristics, including the IS 21348:2007 spectral category and sub-category, wavelength range, solar source temperature region, solar source feature, altitude region of terrestrial atmosphere absorption at unit optical depth, and terrestrial atmosphere thermal processes in the region of maximum energy absorption, are described. We also summarize for each solar index the facility and instrument(s) used to observe the solar emission, the time frame over which the data exist, the measurement cadence, the data latency, and the research as well as operational availability. The new solar indices are provided in forecast as well as real time and historical time frames (http://SpaceWx.com JB2006 Quicklink). We describe the forecast methodology, compare results with actual data for active and quiet solar conditions, and compare improvements in F10.7forecasting with legacy HASDM and NOAA SWPC forecasts.
