| 摘 要： | 利用甘肃黑河流域不同下垫面的近地面气象和辐射观测数据,对已有的12个晴天大气下行长波辐射参数化模型和8个云天模型进行比较.指出晴天情况下Idso模型和Dilley & Obrien模型最适用,但后者一定要进行系数校正,云天情况下Maykut模型误差最小.经过平均日变化分析表明,晴天模型能较好地抓住大气下行长波辐射的日变...

| Abstract: | Several widely used downward atmospheric longwave radiation parameterizations for both clear-sky and all-sky were tested against 10-minutes measured data from four stations at different surfaces in Heihe River Basin,northwest China.It can be inferred from the result that the Idso clear-sky equation was in good agreement with the observed data in all stations,even without adjustment to the observations,while Dilley & Obrien equation had the best result after being adjusted.Both equations were more sensitive ... |
