在2012年中游试验期间，委托张掖观象台开展基于L波段探空系统的常规探空加密观测，同时收集1天2次的观测数据，从而获取8:00、14:00和20:00一天3次的探空观测资料。该数据用于支持航空遥感影像和卫星影像的大气校正工作，同时也可以支持气象分析。
观测地点：
张掖国家气候观象台，张掖城西20km沙井镇，观测点坐标为：39°5'15.68\"N，100°16'39.11\"E。\n测量仪器：
国家气象局业务L波段探空系统。\n测量时间：
2012年6月1日至8月31日共计92天连续观测，观测时间为7:00-8:00、13:00-14:00和19:00-20:00。2012年5月1日-31日和9月1日之30日观测时间为7:00-8:00和19:00-20:00。
数据内容：
风、温、湿、压等要素的大气廓线数据，观测频率为2秒钟1次，观测高度30000米左右。
