微波輻射計是一款被動式地基微波遙感設(shè)備,微波遙感起步晚于可見光和紅外遙感。微波輻射計主要用于中小尺度天氣現(xiàn)象,如暴風(fēng)雨、閃電、強降雨、霧、冰凍及邊界層紊流。對于短時間內(nèi)生成或消散的中小尺度天氣災(zāi)害,雖然只是地區(qū)性的,但部分事件危害性較大。在目前中尺度天氣現(xiàn)象監(jiān)測過程中,探空氣球和天氣雷達(dá)是常用的手段。探空氣球會受到使用時間和空間的限制;天氣雷達(dá)資料基本局限于降雨過程無降水時的欠缺;在離地面5公里范圍內(nèi)衛(wèi)星遙感數(shù)據(jù)存在較大的誤差。被動式地基微波輻射計的出現(xiàn),*上述研究方法監(jiān)測方面的空白,是其有效的補充手段。
微波輻射具有獨立工作能力,能在幾乎各種環(huán)境條件工作, 非常適合于自動天氣站。用于反演完整的大氣廓線,反演數(shù)據(jù)和原始數(shù)據(jù)全部保存。提供完備的顧客定制或標(biāo)準(zhǔn)算法。主要應(yīng)用如下:對流層剖面的溫度、濕度和液態(tài)水,天氣和氣候模型研究,衛(wèi)星追蹤(GPS,伽利略)濕/干延遲和濕度廓線,臨近預(yù)報大氣穩(wěn)定性(災(zāi)害性天氣檢測),溫度反演檢測、霧、空氣污染,校準(zhǔn)云雷達(dá),濕/干延遲改正VLBI。微波遙感可用于地表植被、土壤水分的遙感研究。
