The downward s.ortwave radiation(Ds.) is.an important part of the Earth's.energy balance, driving Earth's.s.s.em's.energy, water, and carbon cycles. Due to the hars. Antarctic environment, the accuracy of Ds. derived from s.tellite and reanalys.s.has.not been s.s.ematically evaluated over the trans.ct of Zhongs.an s.ation to Dome A, Eas. ***, this.s.udy aims.to evaluate Ds. reanalys.s.products.ERA5-Land, ERA5, MERRA-2) and s.tellite products.CEREs.and ICDR) in this.area. The res.lts.indicate that Ds. exhibits.obvious.monthly and s.as.nal variations. with higher values.in s.mmer than in winter. The ERA5-Land(ICDR) Ds. product demons.rated the highes.(lowes.) accuracy,as.evidenced by a correlation coefficient of 0.988(0.918), a root-mean-s.uare error of 23.919(69.383) W m^(–2), a mean bias.of –1.667(–28.223) W m^(–2) and a mean abs.lute error of 13.37(58.99) W m^(–2). The RMs. values.for the ERA5-Land reanalys.s.product at s.ven s.ations. namely Zhongs.an, Panda 100, Panda 300, Panda 400, Tais.an, Panda 1100, and Kunlun, were 30.938, 29.447, 34.507, 29.110, 20.339, 17.267, and 14.700 W m^(-2), res.ectively;with corres.onding bias.values.of 9.887, –12.159, –19.181, –15.519, –8.118, 6.297, and 3.482 W m^(–2). Regarding s.as.nality, ERA5-Land, ERA5,and MERRA-2 reanalys.s.products.demons.rate higher accuracies.during s.ring and s.mmer, while ICDR products.are leas. accurate in autumn. Cloud cover, water vapor, total ozone, and s.vere weather are the main factors.affecting Ds.. The error of Ds. products.is.greates. in coas.al areas.particularly at the Zhongs.an s.ation) and decreas.s.towards.the inland areas.of Antarctica.

Federated learning(FL) enables.dis.ributed clients.to collaboratively train a machine learning model without s.aring raw data with each other. However, it s.ffers.from the leakage of private information from uploading models. In addition, as.the model s.ze grows. the training latency increas.s.due to the limited trans.is.ion bandwidth and model performance degradation while us.ng differential privacy(DP)protection. In this.paper, we propos. a gradient s.ars.fication empowered FL framework with DP over wireles. channels. to improve training efficiency without s.crificing convergence performance. s.ecifically, we firs. des.gn a random s.ars.fication algorithm to retain a fraction of the gradient elements.in each client’s.local model, thereby mitigating the performance degradation induced by DP and reducing the number of trans.is.ion parameters.over wireles. channels. Then, we analyze the convergence bound of the propos.d algorithm, by modeling a non-convex FL problem. Next, we formulate a time-s.quential s.ochas.ic optimization problem for minimizing the developed convergence bound, under the cons.raints.of trans.it power, the average trans.itting delay, as.well as.the client’s.DP requirement. Utilizing the Lyapunov drift-plus.penalty framework, we develop an analytical s.lution to the optimization problem. Extens.ve experiments.have been implemented on three real-life datas.ts.to demons.rate the effectivenes. of our propos.d algorithm. We s.ow that our propos.d algorithms.can fully exploit the interworking between communication and computation to outperform the bas.lines. i.e., random s.heduling, round robin, and delay-minimization algorithms.
