Marquette, Michigan Ground Observations and Atmospheric River Dataset

This dataset contains ground-based meteorological observations and accompanying atmospheric river data used in "The influence of atmospheric rivers on cold-season precipitation in the Upper Great Lakes region", Mateling, Pettersen, Kulie, Mattingly, Henderson, and L'Ecuyer, submitted to GRL, in review.

The ground-based data contains meteorological data including temperature, wind speed and direction, radar reflectivity and Doppler velocity from a Micro-Rain Radar2 (MRR) and precipitation data from a Precipitation Imaging Package (PIP) hosted at the National Weather Service in Marquette, Michigan (Pettersen, Kulie, et al., 2020; Pettersen, Bliven, et al., 2020; Kulie et al., 2021).

The atmospheric river (AR) data contains a flag to identify when an AR is within 100 km of Marquette during a deep cold-season precipitation event. Additionally, the associated integrated water vapor transport (IVT) and motion vectors are within this file. The AR database was created and analyzed in Mattingly et al. (2018).

本数据集包含用于《大气河流对大湖上游地区冷季降水的影响》（作者：Mateling、Pettersen、Kulie、Mattingly、Henderson与L'Ecuyer，已提交至《地球物理研究通讯》（Geophysical Research Letters，GRL）并处于审稿阶段）研究的地面气象观测数据及配套大气河流数据。

地面观测数据涵盖多类气象要素：温度、风速与风向、微型降雨雷达2型（Micro-Rain Radar2，MRR）测得的雷达反射率与多普勒速度，以及部署于密歇根州马凯特国家气象局的降水成像套件（Precipitation Imaging Package，PIP）获取的降水数据（Pettersen、Kulie等，2020；Pettersen、Bliven等，2020；Kulie等，2021）。

大气河流（Atmospheric River，AR）数据包含标记字段，用于识别强冷季降水事件期间，大气河流是否位于马凯特周边100公里范围内。此外，该数据集还包含相关的整层水汽输送（Integrated Water Vapor Transport，IVT）与运动矢量。本大气河流数据库由Mattingly等（2018）构建并开展分析。
