AGS-PRF: Quantifying Microburst Precipitation

微暴流（英语：Microburst）是来自辐射带的电子沉淀，发生在短暴流（~ 100毫秒）中。 虽然每次爆发的粒子损失非常小，但它们的数量足够大，以至于辐射带的总损失可能很大。 这是一项大气和地球空间博士后研究金，目的是确定辐射带以微暴流形式造成的总损失。该研究将使用来自即将到来的NSF资助的FIREBIRD CubeSats，货车艾伦探测器使命和BARREL气球阵列的观测。 FIREBIRD卫星将在两个低海拔地点提供降水观测，BARREL气球阵列将在地球附近提供多个几乎静止的观测。 货车艾伦探测器将为背景提供辐射带观测。在每个位置将有多个同时观察。 它们将决定微暴流的大小和频率。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职业抱负。 如果微下击暴流成为辐射带损失的重要机制，这一研究将对空间天气研究产生影响。

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.
