基于探空和SSMI/S资料的AMSR-2海上大气可降水产品检验与评估
Validation and evaluation of AMSR-2-derived total precipitable water over sea surface using radiosonde and SSMI/S data
摘要
Abstract
A validation of the total precipitable water (TPW) over sea surface derived from advanced microwave scanning radiometer-2 (AMSR-2) from July 2012 to June 2016 is conducted by comparing the special sensor mi-crowave imager/sounder (SSMI/S-F16) and island radiosonde data. It is shown that the amount of TPW derived from AMSR-2 is consistent with that of the island radiosonde data with a mean difference of 0.35 mm. The struc-tures and the characteristics of monthly mean TPW derived from AMSR-2 are quite similar to those of SSMI/S-F16 in the Inter-tropical Convergence Zone, South Pacific Convergence Zone, and South Atlantic Convergence Zone from 2012 to 2016. The mean difference between AMSR-2 and SSMI/S-F16 is –0.04 mm, while the standard devia-tion is 1.21 mm.关键词
