塔克拉玛干沙漠是亚洲尘埃颗粒的主要持续来源，会造成显着的直接辐射效应，通常通过气溶胶太阳辐射强迫（ASRF）来量化。为了提高沙尘ASRF估算的准确性，2019年4月在塔克拉玛干沙漠附近开展了喀什沙尘气溶胶观测（DAO-K）活动。DAO-K活动的目标是提供ASRF计算所需的关键参数，如沙尘光学和微物理特性、垂直分布和地表反照率等。 ASRF 是根据观测到的气溶胶参数，使用辐射传输 (RT) 模拟进行计算的，另外还考虑了测量到的大气剖面和地表反照率的日变化。结果，大气顶部的ASRF日平均值为-19 Wm(-2)，大气底部的ASRF日平均值为-36 W m(-2)，这是根据DAO-K活动期间进行的模拟得出的。此外，利用化学天气研究与预报模型（WRF-Chem），同化了气溶胶光学深度和空气动力直径小于2.5μm（PM2.5）和10μm（PM10）的颗粒物（PM）质量浓度的测量结果，用于估算灰尘ASRF以进行比较。 ASRF模拟（RT和WRF-Chem）的结果使用地基向下太阳辐照度测量进行了评估，这证实了RT模拟与同时观测结果非常一致，而WRF-Chem估计则与太阳辐照度测量结果存在明显差异。
The Taklimakan Desert is a main and continuous source of Asian dust particles causing significant direct radiative effects, which are commonly quantified by the aerosol solar radiative forcing (ASRF). To improve the accuracy of estimates of dust ASRF, the Dust Aerosol Observation-Kashi (DAO-K) campaign was carried out near the Taklimakan Desert in April 2019. The objective of the DAO-K campaign is to provide crucial parameters needed for the calculation of ASRF, such as dust optical and microphysical properties, vertical distribution, and surface albedo. The ASRF was calculated using radiative transfer (RT) simulations based on the observed aerosol parameters, additionally considering the measured atmospheric profiles and diurnal variations of surface albedo. As a result, daily average values of ASRF of -19 Wm(-2) at the top of the atmosphere and -36 W m(-2) at the bottom of the atmosphere were derived from the simulations conducted during the DAO-K campaign. Furthermore, the Weather Research and Forecasting model with Chemistry (WRF-Chem), with assimilation of measurements of the aerosol optical depth and particulate matter (PM) mass concentrations of particles with aerodynamic diameter smaller than 2.5 mu m (PM2.5) and 10 mu m (PM10), is employed to estimate the dust ASRF for comparison. The results of the ASRF simulations (RT and WRF-Chem) were evaluated using ground-based downward solar irradiance measurements, which have confirmed that the RT simulations are in good agreement with simultaneous observations, whereas the WRF-Chem estimations reveal obvious discrepancies with the solar irradiance measurements.
