结果表明，数据能够较好地再现研究区地表辐射通量的空间分布。由于沙尘气溶胶在沙尘源区（DSR）中的存在，地表短波（SW）辐射呈现出明显的低值区，而模型也成功捕捉到了这一特征。模型模拟得到的下行短波、下行长波和上行长波辐射的平均值在三个区域中均与 CERES 较为接近。结果显示，在西北地区，CERES 与 WRF-Chem 在 TOA 的平均净辐射通量分别为 250 W/m² 和 211 W/m²，在 SFC 的分别为 257 W/m² 和 210 W/m²。总体而言，数据较好地反映了中国西北地区辐射通量的空间分布。", "ds_acq_start_time": "2014-04-23 00:00:00", "ds_acq_end_time": "2019-03-21 00:00:00", "ds_acq_place": "中国西北", "ds_acq_lon_east": 123.0, "ds_acq_lat_south": 15.0, "ds_acq_lon_west": 72.0, "ds_acq_lat_north": 50.0, "ds_acq_alt_low": null, "ds_acq_alt_high": null, "ds_share_type": "apply-access", "ds_total_size": 1381912797, "ds_files_count": 2, "ds_format": ".nc", "ds_space_res": "2700", "ds_time_res": "时", "ds_coordinate": "其他", "ds_projection": "Lambert", "ds_thumbnail": "d2c270fa-cfde-4a6b-8377-fc5336187f30.png", "ds_thumb_from": 2, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "Su, S., Wang, J., Yin, Z., Wang, T., Yasheng, D., **e, X., ... & Yang, Y.

The results indicate that the data can well reproduce the spatial distribution of surface radiation flux in the study area. Due to the presence of dust aerosols in the dust source region (DSR), the surface shortwave (SW) radiation exhibits a significant low value area, which was successfully captured by the model. The average values of downlink shortwave, downlink longwave, and uplink longwave radiation simulated by the model are relatively close to CERES in all three regions. The results showed that in the northwest region, the average net radiation fluxes of CERES and WRF Chem in TOA were 250 W/m ² and 211 W/m ², respectively, while in SFC they were 257 W/m ² and 210 W/m ², respectively. Overall, the data well reflects the spatial distribution of radiation flux in northwest China.", "ds_ref_way": "", "ds_abstract": "
The direct radiation effect of dust aerosols has an undeniable impact on regional and global climate.
