A joint NSF and DOE Atmospheric Radiation Measurement (ARM) West Antarctic Radiation Experiment (AWARE, PLR-1443549), is currently collecting a wide range of meteorological, radiation, and cloud microphysical data from McMurdo, Ross Island and also in part at the West Antarctic Ice Sheet (WAIS) Divide field camp. These observational efforts will serve to better characterize Antarctic climate.This RAPID award will additionally allow a US PI to participate in the French field program at Dome C entitled "Improving Model Parameterization of Energetic Fluxes in the Boundary Layer over Antarctica - CALVA." In addition to planned collaboration between the PI with her French colleagues from Laboratoire de Geophysique et Geophysique de l'Environnement (LGGE), there is expected to be a collaboration with the science teams for the joint AWARE and CALVA efforts.One AWARE objective is to observe the impact of long-range moisture transport from Southern Ocean storm tracks on cloud formation and microphysics, and ultimately to better understand the surface radiation and energy budget over Antarctic regions vulnerable to ice mass loss. Comparing AWARE measurement sets to the high terrain of East Antarctica, at Dome C, will allow conclusions as to the ice mass balance to be reached throughout the larger continental area. It is for this concurrency of data intensive measurement campaigns that a RAPID award is desirable and appropriate.

美国国家科学基金会和美国能源部联合进行的南极西部大气辐射测量实验(WARE，PLR-1443549)目前正在从麦克默多、罗斯岛和部分西南极冰盖分割野外营地收集广泛的气象、辐射和云微物理数据。这些观测工作将有助于更好地描述南极气候。这一快速奖励还将允许一名美国PI参与法国在Dome C的现场计划，该计划名为“改进南极-卡尔瓦上空边界层中能量通量的模式参数化”。除了国际地球物理研究所和L地球物理环境实验室的法国同事之间计划的合作外，预计还将与科学团队合作，共同开展AWARE和CARVA的工作。AWARE的一个目标是观察南大洋风暴路径的远程水汽输送对云形成和微物理的影响，并最终更好地了解南极地区易受冰层质量丧失影响的地表辐射和能量收支。将AWARE测量设备与位于穹顶C的东南极洲的高地形进行比较，可以得出整个更大的大陆地区的冰块平衡的结论。正是对于这种数据密集型测量活动的并发性，快速奖励是可取的和适当的。
