AGS-PRF: Quantifying Microburst Precipitation

微爆发是从辐射带中产生的电子沉淀，发生在短爆发中（~100ms）。虽然每次爆发的粒子损失非常小，但它们的数量足够大，辐射带的总损失可能是显著的。这是一个大气和地球空间博士后研究项目，旨在确定微爆发形式的辐射带总损失。这项研究将使用即将到来的美国国家科学基金会资助的火鸟立方体卫星、范艾伦探测器任务和BARREL气球阵列的观测结果。火鸟卫星将在两个低空位置提供降水观测，BARREL气球阵列将在地球附近提供多个近静止观测。范艾伦探测器将提供辐射带观测资料。在每个位置将有多个同时观测。它们将决定微爆炸的大小和频率。该奖项将为斯坦福大学的一名年轻研究人员提供早期职业培训。这个项目将支持他成为一名乐器演奏家的事业抱负。如果微暴是辐射带的重要损失机制，将对空间气象研究产生重要影响。

Microbursts are electron precipitation from the radiation belts that occur in short bursts (~100ms). Although the particle loss from each burst is very small, they occur in sufficiently large numbers that the total loss from the radiation belts may be significant. This is an Atmospheric and Geospace Post-doctoral Fellowship to determine the total loss from the radiation belts in the form of microbursts. The study will use observations from the forthcoming NSF funded FIREBIRD CubeSats, the Van Allen Probes mission and the BARREL balloon array. The FIREBIRD satellites will provide observations of precipitation at two low altitude locations and the BARREL balloon array will provide multiple nearly stationary observations near the Earth. The Van Allen Probes will provide radiation belt observations for context. At each position there will be multiple simultaneous observations. They will determine the size and frequency of microbursts. This award will provide early career training for a young researcher at Stanford. This project will support his career ambition to be an instrumentalist. If microbursts turn out to be an important loss mechanism for the radiation belts this research will have impact on space weather research.
