Jason-2高度计OGDR-BUFR风浪产品根据现有观测和ECMWF模型场进行了业务验证。Ku波段有效波高(SWH)优于JASON-1。但是，地面风速还需要改进。通过多次数值试验，证明了在ECMWF波模式中同化Jason-2 SWH的积极作用。Jason-2 SWH于2009年3月10日更换了Jason-1。在移动到一个新的轨道后，Jason-1 SWH也被证明具有有限但积极的影响，导致它在2009年6月8日重新引入ECMWF系统。
Jason-2 altimeter OGDR-BUFR wind and wave products are validated operationally against available observations and ECMWF model fields. The Ku-band significant wave height (SWH) is better than its Jason-1 counterpart. However, the surface wind speed needs some improvements. The positive impact of assimilating Jason-2 SWH in the ECMWF wave model was proved through several numerical experiments. Jason-2 SWH replaced Jason-1 operationally on 10 March 2009. After its move to a new orbit, Jason-1 SWH was also proved to have limited, yet positive impact leading to its reintroduction into the ECMWF system on June 8, 2009.
