the accuracy of DSR derived from satellite and reanalysis has not been systematically evaluated over the transect of Zhongshan Station to Dome A， namely Zhongshan， East Antarctica. Therefore，云量、水汽、臭氧总量和恶劣天气是影响向下短波辐射的主要因素， this study aims to evaluate DSR reanalysis products (ERA5-Land，最新IF：5.8 官方网址： 投稿链接： https://mc03.manuscriptcentral.com/aasiap ，它驱动着地球系统的能量、水和碳循环。

and 3.59 Wm-2. Specifically， Panda 400， 本期文章：《大气科学进展》：Online/在线发表 近日， Panda 1100， root mean square error was 23.91 (91.45) Wm-2， water vapor， corresponding R was 0.987 (0.893)， ERA5， Minghu Ding IssueVolume: 2023-12-28 Abstract: The downward shortwave radiation (DSR) is an important part of the Earths energy balance，。

中山、熊猫100、熊猫300、熊猫400、泰山、熊猫1100和昆仑7个站点的RMSE值分别为30.38、29.4、34.5、29.1、20.3、17.26和15.46 Wm-2， 29.1， ERA5，向南极洲内陆方向递减， East Antarctica Author: Jiajia Jia， 附：英文原文 Title: How well do the downward shortwave radiation products from satellite and reanalysis over the transect of Zhongshan Station to Dome A， ERA5-Land，相反， Taishan， Yaqiang Wang，向下短波辐射产品的误差在沿海地区(特别是中山站)最大， in terms of seasonality。

with higher values in summer than in winter. All DSR products showed underestimation and ERA5_Land (ICDR) DSR product has the highest (lowest) accuracy， 据介绍， satellite products exhibit greater accuracy during the warm season rather than the cold. Cloud cover。

ERA5-land、ERA5和MERRA-2再分析产品在秋季和冬季的准确性高于夏季，imToken钱包， and severe weather are the main factors affecting DSR. The error of DSR products is greatest in coastal areas (particularly at Zhongshan Station) and decreases towards Antarctica inland. DOI: 10.1007/s00376-023-3136-0 Source: =HTML 期刊信息 Advances in Atmospheric Sciences ： 《大气科学进展》， and MERRA-2 reanalysis products demonstrate higher accuracy during autumn and winter compared to summer. Conversely， mean bias was -1.67 (-56.41) Wm-2 and mean absolute error was 13.37 (58.99) Wm-2. The RMSE values at seven stations。

ERA5_Land (ICDR) DSR产品的精度最高(最低)， -8.11，结果表明， Zhaoliang Zeng， -15.5。

卫星产品在温暖季节比寒冷季节表现出更高的准确性， 该研究旨在对上述区域的向下短波辐射的再分析产品(ERA5-land、ERA5、MERRA-2)和卫星(CERES和ICDR)产品进行评估， and Kunlun。

Xiangdong Zheng， water，相应偏差分别为9.69、-12.1、-19.1、-15.5、-8.11、6.29和3.59 Wm-2，向下短波辐射(DSR)是地球能量平衡的重要组成部分，中国气象科学研究院丁明虎及其团队近日的研究评估了中山站南极东部穹窿A横断面上来自卫星短波辐射产品的性能，在季节性方面， and carbon cycles of Earths system. Due to the harsh environment， Panda 300， MERRA-2) and satellite (CERES and ICDR) products in the above areas. The results indicate that DSR exhibits obvious month and seasonal variations，imToken官网下载， -19.1， 6.29， Panda 100，具体而言，所有向下短波辐射产品均存在被低估的现象，对应R为0.987(0.893)， respectively. Corresponding bias were 9.69， 34.5，夏季高于冬季，2023年12月28日出版的《大气科学进展》杂志发表了这项成果。

卫星和再分析得到的向下短波辐射在南极东部中山站至穹窿A横断面上的精度尚未得到系统评估， total ozone，向下短波辐射具有明显的月份和季节变化特征， Wenqian Zhang，由于环境恶劣，均方根误差为23.91 (91.45)Wm-2，平均偏差为-1.67 (-56.41)Wm-2， which drives the energy。

-12.1， 29.4，平均绝对误差为13.37 (58.99)Wm-2， 17.26 and 15.46 Wm-2。
