在(zai)小(xiao)氣候調查中，例如(ru)在(zai)研究(jiu)冷氣流的(de)厚度(du)等工作時，需(xu)要觀測(ce)氣溫的(de)垂直(zhi)分布。在(zai)這種場合，可使(shi)用供遙測(ce)用的(de)溫度(du)表(biao)。這類(lei)溫度(du)表(biao)的(de)代表(biao)是熱(re)電(dian)偶和熱(re)敏電(dian)阻溫度(du)表(biao)。

熱(re)敏(min)(min)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)溫(wen)(wen)(wen)(wen)(wen)度(du)表是(shi)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)溫(wen)(wen)(wen)(wen)(wen)度(du)表的(de)(de)(de)一種。這種溫(wen)(wen)(wen)(wen)(wen)度(du)表是(shi)利用(yong)金(jin)屬的(de)(de)(de)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)隨著(zhu)溫(wen)(wen)(wen)(wen)(wen)度(du)的(de)(de)(de)變(bian)化而變(bian)化的(de)(de)(de)性(xing)(xing)質做成(cheng)的(de)(de)(de)。熱(re)敏(min)(min)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)是(shi)在(zai)幾種金(jin)屬氧化物的(de)(de)(de)粉末中加進粘土、糊劑等鑄成(cheng)。其溫(wen)(wen)(wen)(wen)(wen)度(du)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)特性(xing)(xing)表現為，在(zai)低溫(wen)(wen)(wen)(wen)(wen)情(qing)況(kuang)下電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)大(da)，而高溫(wen)(wen)(wen)(wen)(wen)情(qing)況(kuang)下電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)小。測(ce)溫(wen)(wen)(wen)(wen)(wen)用(yong)的(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)表在(zai)常溫(wen)(wen)(wen)(wen)(wen)下為10千(qian)歐姆(mu)左右(you)，溫(wen)(wen)(wen)(wen)(wen)度(du)系數為-4%左右(you)，較普(pu)通的(de)(de)(de)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)溫(wen)(wen)(wen)(wen)(wen)度(du)表要大(da)得多。因此，有導線電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)影響小、容易(yi)作遙測(ce)的(de)(de)(de)特征。在(zai)室(shi)外觀測(ce)氣溫(wen)(wen)(wen)(wen)(wen)時(shi)，跟(gen)普(pu)通的(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)表一樣，仍然(ran)需要安(an)裝防(fang)輻射罩。

一般說來，熱敏電(dian)(dian)阻的(de)(de)阻值(zhi)在(zai)幾十(shi)千歐，不到(dao)10歐的(de)(de)導(dao)線電(dian)(dian)阻隨溫度(du)變化的(de)(de)影響*可以(yi)忽略不計，但是必(bi)須注(zhu)意(yi)元件(jian)表(biao)面(mian)的(de)(de)漏電(dian)(dian)，元件(jian)表(biao)面(mian)受潮后，可能使它并聯進去一個與元件(jian)阻值(zhi)相當的(de)(de)漏電(dian)(dian)電(dian)(dian)阻，因而產(chan)生(sheng)較大的(de)(de)測溫誤差(cha)，投人使用前的(de)(de)熱敏電(dian)(dian)阻，必(bi)須在(zai)它的(de)(de)表(biao)面(mian)涂上較好的(de)(de)防潮材料，

使用熱(re)敏(min)電(dian)阻(zu)，須(xu)特(te)別注意電(dian)流(liu)(liu)對元件的(de)(de)電(dian)功率増(zeng)溫(wen)，在較大的(de)(de)電(dian)流(liu)(liu)下，熱(re)敏(min)電(dian)阻(zu)的(de)(de)負溫(wen)度系(xi)數有可能導致過熱(re)失控，電(dian)流(liu)(liu)增溫(wen)使元件阻(zu)值(zhi)減小的(de)(de)同時(shi)，將進(jin)一步增大流(liu)(liu)經(jing)的(de)(de)電(dian)流(liu)(liu)，并同時(shi)加大增溫(wen)效應。

熱敏(min)電(dian)阻溫(wen)(wen)度(du)(du)表(biao)(biao)，感應元件由幾種(zhong)金屬氧化(hua)物混(hun)合(he)燒結成的導體電(dian)阻，電(dian)阻值通常幾十千歐，其電(dian)阻溫(wen)(wen)度(du)(du)系數大，靈敏(min)度(du)(du)高(gao)于(yu)金屬電(dian)阻溫(wen)(wen)度(du)(du)表(biao)(biao)，但穩定性稍差，廣泛應用于(yu)高(gao)空遙測。顛(dian)(dian)(dian)倒(dao)溫(wen)(wen)(wen)(wen)度(du)表是一種特殊的(de)玻璃水(shui)銀溫(wen)(wen)(wen)(wen)度(du)表。可分(fen)為測(ce)量水(shui)溫(wen)(wen)(wen)(wen)的(de)閉端(duan)顛(dian)(dian)(dian)倒(dao)溫(wen)(wen)(wen)(wen)度(du)表和(he)測(ce)量水(shui)深的(de)開(kai)端(duan)顛(dian)(dian)(dian)倒(dao)溫(wen)(wen)(wen)(wen)度(du)表。由于其(qi)特殊的(de)結構和(he)制作方法，在(zai)現場觀測(ce)時，當(dang)顛(dian)(dian)(dian)倒(dao)溫(wen)(wen)(wen)(wen)度(du)表取上來后。溫(wen)(wen)(wen)(wen)度(du)表示數仍為顛(dian)(dian)(dian)倒(dao)處當(dang)時的(de)溫(wen)(wen)(wen)(wen)度(du)和(he)深度(du)，至今(jin)仍在(zai)海洋調查中使用。

大(da)(da)氣(qi)(qi)探(tan)(tan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)按照探(tan)(tan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)方法可分為目測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)、器測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)兩類。目測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)指的(de)(de)(de)(de)(de)(de)是憑借(jie)目力(li)或借(jie)助輔(fu)助儀器進(jin)行的(de)(de)(de)(de)(de)(de)觀(guan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)，主要(yao)(yao)由(you)觀(guan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)員用(yong)肉(rou)眼觀(guan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)，主要(yao)(yao)應用(yong)于(yu)氣(qi)(qi)象臺站對(dui)云、能見度、天氣(qi)(qi)現象及其演變過程(cheng)的(de)(de)(de)(de)(de)(de)觀(guan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)。器測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)又(you)分為直接(jie)(jie)觀(guan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)和遙感(gan)探(tan)(tan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)，直接(jie)(jie)觀(guan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)指將儀器的(de)(de)(de)(de)(de)(de)感(gan)應元(yuan)件(jian)(jian)直接(jie)(jie)置于(yu)待測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)大(da)(da)氣(qi)(qi)之中，根(gen)據元(yuan)件(jian)(jian)性質的(de)(de)(de)(de)(de)(de)變化(hua)，得到描述大(da)(da)氣(qi)(qi)狀況的(de)(de)(de)(de)(de)(de)氣(qi)(qi)象參數，例(li)如氣(qi)(qi)壓表、溫(wen)度表、濕(shi)度表等；遙感(gan)探(tan)(tan)測(ce)(ce)(ce)(ce)(ce)(ce)(ce)(ce)指根(gen)據電磁波在大(da)(da)氣(qi)(qi)中傳播過程(cheng)中信號的(de)(de)(de)(de)(de)(de)變化(hua)，反(fan)演出大(da)(da)氣(qi)(qi)中氣(qi)(qi)象要(yao)(yao)素的(de)(de)(de)(de)(de)(de)變化(hua)，例(li)如氣(qi)(qi)象雷(lei)達(da)、聲(sheng)雷(lei)達(da)（聲(sheng)波大(da)(da)氣(qi)(qi)遙感(gan)）、氣(qi)(qi)象雷(lei)達(da)（激光大(da)(da)氣(qi)(qi)遙感(gan)）、紅(hong)外(wai)輻射（紅(hong)外(wai)大(da)(da)氣(qi)(qi)遙感(gan)）等。

大(da)氣(qi)(qi)探(tan)(tan)(tan)測(ce)(ce)(ce)系(xi)統(tong)(tong)按(an)照(zhao)傳感器(qi)(qi)所處位置可分為天基(ji)(ji)(ji)觀(guan)(guan)測(ce)(ce)(ce)、空(kong)基(ji)(ji)(ji)觀(guan)(guan)測(ce)(ce)(ce)和(he)(he)地(di)(di)(di)基(ji)(ji)(ji)觀(guan)(guan)測(ce)(ce)(ce)系(xi)統(tong)(tong)。傳感器(qi)(qi)在中(zhong)層大(da)氣(qi)(qi)之外的為天基(ji)(ji)(ji)觀(guan)(guan)測(ce)(ce)(ce)，主(zhu)(zhu)要(yao)由低軌衛星和(he)(he)高軌衛星以及相應的地(di)(di)(di)面應用系(xi)統(tong)(tong)組(zu)成；傳感器(qi)(qi)在地(di)(di)(di)球(qiu)(qiu)表面以上、中(zhong)層大(da)氣(qi)(qi)及以下的為空(kong)基(ji)(ji)(ji)觀(guan)(guan)測(ce)(ce)(ce)，主(zhu)(zhu)要(yao)由氣(qi)(qi)球(qiu)(qiu)探(tan)(tan)(tan)測(ce)(ce)(ce)、飛機探(tan)(tan)(tan)測(ce)(ce)(ce)和(he)(he)火箭(jian)探(tan)(tan)(tan)測(ce)(ce)(ce)組(zu)成；傳感器(qi)(qi)在地(di)(di)(di)球(qiu)(qiu)表面的為地(di)(di)(di)基(ji)(ji)(ji)觀(guan)(guan)測(ce)(ce)(ce)，主(zhu)(zhu)要(yao)由地(di)(di)(di)面氣(qi)(qi)象(xiang)觀(guan)(guan)測(ce)(ce)(ce)、地(di)(di)(di)基(ji)(ji)(ji)氣(qi)(qi)候系(xi)統(tong)(tong)觀(guan)(guan)測(ce)(ce)(ce)、地(di)(di)(di)基(ji)(ji)(ji)遙感探(tan)(tan)(tan)測(ce)(ce)(ce)、地(di)(di)(di)基(ji)(ji)(ji)大(da)氣(qi)(qi)邊界層觀(guan)(guan)測(ce)(ce)(ce)、地(di)(di)(di)基(ji)(ji)(ji)中(zhong)高層大(da)氣(qi)(qi)和(he)(he)空(kong)間天氣(qi)(qi)監測(ce)(ce)(ce)、地(di)(di)(di)基(ji)(ji)(ji)移動氣(qi)(qi)象(xiang)觀(guan)(guan)測(ce)(ce)(ce)、地(di)(di)(di)基(ji)(ji)(ji)氣(qi)(qi)象(xiang)觀(guan)(guan)測(ce)(ce)(ce)運行監控(kong)和(he)(he)技術保障(zhang)等組(zu)成。
