中国130个站点44年逐日有效辐射数据集（1971-2014）

地面有效辐射作为地面辐射平衡的重要分量和地-气之间能量交换的重要形式之一，在研究气温日变化规律、预报最低气温、辐射雾和辐射霜冻等方面发挥重要作用。作者基于国家气象信息中心提供的1993-2012年中国气象辐射基本要素日值数据和1971-2014年中国地面气象要素日值数据集，利用步长加速法和多元回归法迭代求解最优参数，建立了适用于中国的有效辐射新的参数化模型，并利用该模型计算得到中国130个辐射站44年逐日有效辐射数据集（1971-2014年）。该数据集包括：（1）130个辐射站原始资料的基本信息，包括资料时段、缺测时段等信息；（2）基于有效辐射新的参数化模型计算得到的130个辐射站1971-2014年间的逐日有效辐射值（Rnl）。数据集以.xls格式存储，由131个数据文件组成，数据量为147 MB（压缩为1个文件，23.7 MB）。该数据集的研究成果发表在《气象学报》2016年74卷第6期。

Surface effective radiation, as a critical component of surface radiation balance and one of the important forms of energy exchange between the land and the atmosphere, plays a vital role in studies of diurnal air temperature variation patterns, forecasting of minimum air temperature, radiation fog, radiation frost, and other related fields.
The authors established a new parameterization model for effective radiation applicable to China based on the daily dataset of basic meteorological radiation elements in China from 1993 to 2012 and the daily dataset of surface meteorological elements in China from 1971 to 2014 provided by the National Meteorological Information Center, using the accelerated step method and multiple regression method to iteratively solve for optimal parameters. Subsequently, they utilized this model to calculate a 44-year daily effective radiation dataset (1971–2014) covering 130 radiation stations across China.
This dataset includes: (1) Basic information of the original data from the 130 radiation stations, such as data time periods, missing data periods, and other relevant details; (2) Daily effective radiation values (Rnl) from 1971 to 2014 for the 130 radiation stations, computed using the aforementioned new effective radiation parameterization model.
The dataset is stored in .xls format, comprising 131 individual data files, with an uncompressed size of 147 MB (compressed to a single file of 23.7 MB).
The research findings based on this dataset were published in *Acta Meteorologica Sinica*, Volume 74, Issue 6, 2016.
