Abstract

Abstract. The Chilean Observation Network De MeteOr Radars (CONDOR) commenced deployment in June 2019 and became fully operational in February 2020. It is a multi-static meteor radar system consisting of three ~1º latitudinally separated stations. The main (central) station is located at the Andes Lidar Observatory (ALO, 30.25º S, 70.74º W) and is used for both transmission and reception. The two remote sites are located to the north and south and are used for reception only. The southern station is located at the Southern Cross Observatory (SCO, 31.20º S, 71.00º W) and the northern station is located at Las Campanas Observatory (LCO, 29.02º S, 70.69º W). The successful deployment and maintenance of CONDOR provide 24/7 measurements of horizontal winds in the mesosphere and lower thermosphere (MLT), and permit the retrieval of spatially resolved horizontal winds, vertical winds, and temperatures. This is possible because of the high meteor detection rates. Over 30,000 quality controlled underdense meteor echoes are detected at the ALO each day and in total ~88,000 events are detected each day over the three sites. In this paper, we present the system configuration of the CONDOR and discuss the validation and initial results of its data products. The motivations of deploying the CONDOR system also include the combination of results with other co-located ground-based instruments at the ALO, which provide uniquely cross-validated and cross-scale observations of the MLT dynamics with multiple scientific goals.

智利气象雷达观测网络（CONDOR）：多静态系统配置及与同地激光雷达的风力比较

摘要智利气象雷达观测网络（CONDOR）于 2019 年 6 月开始部署，2020 年 2 月全面投入运行。这是一个多静态流星雷达系统，由三个纬度相距约 1º 的站点组成。主（中心）站位于安第斯激光雷达观测站（ALO，南纬 30.25º，西经 70.74º），用于发射和接收。两个偏远站点分别位于北面和南面，仅用于接收。南站位于南十字星天文台（SCO，南纬 31.20º，西经 71.00º），北站位于拉斯坎帕纳斯天文台（LCO，南纬 29.02º，西经 70.69º）。CONDOR 的成功部署和维护提供了对中间层和低温层（MLT）水平风的全天候测量，并允许检索空间分辨率的水平风、垂直风和温度。之所以能够做到这一点，是因为流星探测率很高。ALO 每天检测到超过 30,000 次质量受控的低密度流星回波，三个站点每天共检测到约 88,000 次事件。在本文中，我们将介绍 CONDOR 的系统配置，并讨论其数据产品的验证和初步结果。部署 CONDOR 系统的动机还包括将结果与 ALO 的其他共址地面仪器相结合，这些仪器提供了独特的跨验证和跨尺度的 MLT 动态观测，具有多重科学目标。

期刊介绍： Atmospheric Measurement Techniques (AMT) is an international scientific journal dedicated to the publication and discussion of advances in remote sensing, in-situ and laboratory measurement techniques for the constituents and properties of the Earth’s atmosphere. The main subject areas comprise the development, intercomparison and validation of measurement instruments and techniques of data processing and information retrieval for gases, aerosols, and clouds. The manuscript types considered for peer-reviewed publication are research articles, review articles, and commentaries.
