DYNAMO: Colombo, Sri Lanka Radiosonde L3.0 Data. Version 1.0

This dataset includes 258 high vertical resolution soundings from Colombo, Sri Lanka (WMO 43466) collected during the DYNAMO field campaign for 2011-12. Soundings were typically released four times daily (00, 06, 12 and 18 UTC) from 30 September 2011 to 6 December 2011. From 7-28 December soundings were released at most once per day at 12 UTC. The station utilized Meisei RS-06G radiosondes. These soundings were provided by JAMSTEC. This L3.0 version of the data set was released 15 October 2013 and changes include the application of PDF matching and correction for the relative humidity discontinuity at the 0C level. These adjustments were applied by JAMSTEC.本数据集包含258组来自斯里兰卡科伦坡站（世界气象组织（World Meteorological Organization，WMO）站号43466）的高垂直分辨率探空观测数据，采集于2011-2012年的DYNAMO野外试验期间。2011年9月30日至12月6日期间，探空观测通常每日释放四次（世界协调时（Coordinated Universal Time，UTC）00、06、12、18时）；2011年12月7日至28日期间，探空观测每日最多释放一次，释放时间为世界协调时12时。该观测站采用Meisei RS-06G型无线电探空仪，本次探空数据由日本海洋地球科技研究机构（JAMSTEC）提供。本数据集的L3.0版本于2013年10月15日发布，更新内容包括应用概率密度函数（Probability Density Function，PDF）匹配法，以及针对0℃层结处相对湿度不连续现象的修正，上述修正工作由JAMSTEC完成。
