Abstract The Global Positioning System (GPS) provides a relatively inexpensive method to remotely sense atmospheric water vapor in all weather conditions. In this study, we applied the GPS meteorology technique monitor precipitable (PWV) variation during severe event (typhoon EWINIAR). Korean weighted mean temperature equation (KWMTE), customized for Peninsula, was used improve accuracy of PWV estimation. time series and comparison with images MTSAT/CMAX contour maps indicated that temporal...

This paper describes the development of a transformation grid for transforming horizontal spatial data from local geodetic datum to geocentric in Korea. We used least squares collocation as method modelling distortion that remains after application standard seven-parameter similarity transformation. In experimental tests, RMSEs latitude and longitude coordinates are ±0.016m ±0.007m, respectively, modelling, whereas it was indicated accuracy is improved about 98% by correction. reasonable...
AbstractAbstractThis paper presents GPS meteorology using observations obtained from the Korean permanent network during a severe weather condition. Our first experimental studies in Korea were based on data collected seventeen stations and four radiosonde period of Typhoon Rusa 31 August to 1 September 2002. The root mean square difference (RMSD) between Precipitable Water Vapour (PWV) radiosonde-PWV was at 7.2 mm level. In this new study, least analysis used reduce large RMSD without bias,...
인간의 활동뿐만 아니라 연안 지역의 경제적 피해와 환경 보존에 미치는 해안 침식의 영향은 여러 국가 정책 중에서 주요 관심사 중 하나이다. 본 연구에서는 거진항 지역에 위치한 해변을 대상으로 영향을 판단하기 위한 해안선 변화 및 해빈 단변에 대한 물리적 조사를 실시하였다. 조사 결과는 해수면 상승, 폭풍, 고파랑 인위적 건축물에 의한 복잡한 원인들에 의하여 거진 해변에서 명확한 침식이 일어나고 있는 것을 보여주었다. 특히, 자산천 하구 부근에서는 표사 유입으로 인한 안정된 해빈폭을 유지하고 있었으나, 나머지 구간에서는 해빈폭의 전진 현상보다는 후퇴 현상이 증가를 하고 것으로 나타났다. 따라서 GW04 지역은 해안침식에 대하여 불안정한 상태에 놓여 있다고 판단되며, DGPS와 다양한 측량 방법에 지속적인 모니터링 관찰이 필요하다고 본다. Coastal erosion and its impact on human activities as well the economic damage...
본 연구에서는 2011년 강원도 영동 지방의 폭설 기간 동안 GPS 위성 신호의 대류권 지연량 추정으로부터 대기 가강수량을 복원하였다. 폭설이 발생하는 동안에 가강수량과 신적설 발생량과의 상관관계에 대한 분석을 실시하였다. 분석 결과, GPS를 이용하여 복원한 대류권에서의 가강수량 증가가 발생된 이후에 강설량이 증가하는 추세를 나타냈다. 또한 웨이블릿을 이용한 주기 분석에서는 연구기간에 한해서 가강수량의 주기가 포화수증기압의 주기와 유사한 것으로 검출되었다. 감소와 이에 대응하는 신적설량의 증감은 두 연구 지역인 강릉과 울진에서 모두 다르게 증감하는 경향을 상관 계수는 강설이 발생하지 않는 동안의 결과와는 달리 양의 상관성을 갖는 나타났다. In this paper, the precipitable water vapor was retrieved by estimating of signal delay in troposphere during progress heavy snowfall...
Since the accuracy of precipitable/integrated water vapor estimates from GNSS measurements is proportional to Weighted Mean Temperature Model (WMTM), WMTM a significant formulation in retrieval precipitable zenith wet delay signal. The purpose this paper develop available apply for meteorology region Algeria, by using Algerian radiosonde network World Meteorological Organization (WMO). It can be concluded that which retrieved developed Equation (AWMTE) useful technique sensing after...
