  1. Main conclusions drawn from the analyses of calculating results are as follows : ( 1 ) the microwave absorption of atmosphere gas have obvious attenuation at the wavelengths for cloud detection, thereinto, the water attenuation effect changes greatly, so the 94ghz cloud detecting radar should have water vapor attenuation correction scheme. ( 2 ) when 37ghz and 94ghz radars detect clouds, the difference between the atmosphere and cloud attenuation and the large variety of radar reflectivity conduce the intension of the radar backscatter signals change. ( 3 ) for the thin cloud layer and low water content of cloud, 37 - ghz radar backscatter signals are not as good as 94 - ghz radar, that is to say that the 94ghz radar has better capability in thin clouds detection

    本工作得出如下結論: ( 1 )大氣氣體的微波吸收在測雲波段產生明顯的衰減,其中水汽衰減效應變化很大;即將上天的空間94ghz測雲雷達必須有水汽衰減訂正方案; ( 2 ) 37ghz和94ghz雷達測雲,由於大氣和雲衰減不同和雷達反射率的很大差異,導致雷達回波信號強弱不同; ( 3 )對雲層較薄、含水量較少的雲,在不計雷達參數的情況下, 37ghz雷達回波信號不如94ghz測雲雷達,也就是說94ghz對薄雲有更強的探測能力;對雲層較厚、含水量大的雲,由於強衰減的作用, 94ghz雷達回波信號小於37ghz雷達; ( 4 )從大氣衰減的不利因素方面考慮,空間94ghz雷達測高層薄雲的效果最好;測低層薄雲時需要考慮氣體衰減訂正;因濃厚雲的強衰減作用,探測其中下部的能力大大減弱,不僅要進行衰減訂正,而且要藉助其他信息來反演整個雲層的含水量垂直分佈; ( 5 )為了獲得從極薄到極濃厚雲的垂直分佈探測能力,未來測雲雷達系統最好採用雙波長甚至三波長(如94 、 37和13ghz ) 。
  2. ( 2 ) model correction and comparison in the process of conversion from zenith day delay to gps water vapor and precision evaluation. saastamoinen ( sa ) model and hopfield ( h ) for dry delay and bevis model for atmospheric weighted temperature are adopted

    ( 2 )模型訂正與比較在gps水汽反演過程中,一般干延遲和大氣加權平均溫度的計算是採用「普適性」模型,目前應用較多的有saastamoinen ( sa )模型、 hopfield ( h )模型和bevis模型。
  3. The paper have built the local correction models for dry delay and atmospheric weighted temperature and have made a comparison between two models for calculating actual water vapor on the basis of actual upper - air detecting data. ah results show that the conclusion is satisfied

    本研究利用實際探空資料建立了大氣干延遲和大氣加權平均溫度的局地訂正模型,並對實際水汽計算模型進行了比較,得到了滿意的結果。
