| 摘 要： | The ground-based Atmospheric Emitted Radi- ance Interferometer （AERI） was deployed in Shouxian, China in 2008 to measure down-welling infrared radiances with high resolution. Based on AERI observations, we propose a new method for retrieving vertical temperature and water vapor profiles in the planetary boundary layer （PBL）. The method exclusively uses NCEP-2, a global reanalysis data as a first-guess profile in an iterative recursive algorithm. The PBL profiles of temperature and moisture under clear sky conditions in Shouxian have been retrieved using this new method. Compared with coinci- dent radiosonde measurements, we find that AERI is able to obtain more accurate temperature and water vapor pro- files in the PBL. The retrieval results with high temporal resolution can be used to monitor the PBL stability and evolution.
