ARM - Midlatitude Continental Convective Clouds (jensen-sonde)

A major component of the Mid-latitude Continental Convective Clouds Experiment (MC3E) field campaign was the deployment of an enhanced radiosonde array designed to capture the vertical profile of atmospheric state variables (pressure, temperature, humidity wind speed and wind direction) for the purpose of deriving the large-scale forcing for use in modeling studies. The radiosonde array included six sites (enhanced Central Facility [CF-1] plus five new sites) launching radiosondes at 3-6 hour sampling intervals. The network will cover an area of approximately (300)2 km2 with five outer sounding launch sites and one central launch location. The five outer sounding launch sites are: S01 Pratt, KS [ 37.7oN, 98.75oW]; S02 Chanute, KS [37.674, 95.488]; S03 Vici, Oklahoma [36.071, -99.204]; S04 Morris, Oklahoma [35.687, -95.856]; and S05 Purcell, Oklahoma [34.985, -97.522]. Soundings from the SGP Central Facility during MC3E can be retrieved from the regular ARM archive. During routine MC3E operations 4 radiosondes were launched from each of these sites (approx. 0130, 0730, 1330 and 1930 UTC). On days that were forecast to be convective up to four additional launches were launched at each site (approx. 0430, 1030, 1630, 2230 UTC). There were a total of approximately 14 of these high frequency launch days over the course of the experiment.

中纬度大陆对流云实验（Mid-latitude Continental Convective Clouds Experiment, MC3E）外场观测试验的核心组成部分，是部署一套增强型无线电探空（radiosonde）阵列，旨在捕获大气状态变量（气压、气温、湿度、风速与风向）的垂直廓线，以此推导大尺度强迫项，供数值模拟研究使用。
该探空阵列包含6个观测站点：增强型中心设施[CF-1]外加5个新建站点，探空施放的采样间隔为3至6小时。整个观测网络覆盖面积约为(300)²平方千米，设有5个外围探空施放站点与1个中心施放点位。5个外围探空站点分别为：S01 美国堪萨斯州普拉特市（Pratt, KS）[北纬37.7°，西经98.75°]；S02 美国堪萨斯州沙努特市（Chanute, KS）[北纬37.674°，西经95.488°]；S03 美国俄克拉荷马州维西县（Vici, Oklahoma）[北纬36.071°，西经99.204°]；S04 美国俄克拉荷马州莫里斯市（Morris, Oklahoma）[北纬35.687°，西经95.856°]；以及S05 美国俄克拉荷马州珀塞尔市（Purcell, Oklahoma）[北纬34.985°，西经97.522°]。
MC3E期间SGP中心设施的探空数据，可从常规ARM档案库中获取。在MC3E常规作业流程中，每个站点每日施放4次探空，大致对应协调世界时（UTC）0130、0730、1330与1930时刻。若当日预报存在对流天气，则每个站点可额外最多施放4次探空，大致对应协调世界时（UTC）0430、1030、1630与2230时刻。本次试验期间，共计有约14天采用了该高频探空施放方案。
