Observations of precipitable water vapour over complex topography of Ethiopia from ground-based GPS, FTIR, radiosonde and ERA-Interim reanalysis
Water vapour is one of the most important greenhouse gases. Long-term changes in the amount of water vapour in the atmosphere need to be monitored not only for its direct role as a greenhouse gas but also because of its role in amplifying other feedbacks such as clouds and albedo. In recent decades, monitoring of water vapour on a regular and continuous basis has become possible as a result of ...
متن کاملSystematic Errors in Global Radiosonde Precipitable Water Data from Comparisons with Ground-Based GPS Measurements
A global, 10-yr (February 1997–April 2006), 2-hourly dataset of atmospheric precipitable water (PW) was produced from ground-based global positioning system (GPS) measurements of zenith tropospheric delay (ZTD) at approximately 350 International Global Navigation Satellite Systems (GNSS) Service (IGS) ground stations. A total of 130 pairs of radiosonde and GPS stations are found within a 50-km ...
متن کاملRetrieving Precipitable Water Vapor Data Using GPS Zenith Delays and Global Reanalysis Data in China
GPS has become a very effective tool to remotely sense precipitable water vapor (PWV) information, which is important for weather forecasting and nowcasting. The number of geodetic GNSS stations set up in China has substantially increased over the last few decades. However, GPS PWV derivation requires surface pressure to calculate the precise zenith hydrostatic delay and weighted mean temperatu...
متن کاملCalculating of Radiosonde Precipitable water using MODIS Satellite images in Goorganrood basin
Deficiency of atmospheric water vapor profile data is one of most important problems in the flood hazard researches for areas flooding such as Goorganrood basin, because of no radiosonde stations. With the aim of radiosonde data generation retrieved radiance MODIS data, after Geometric and radiometric corrections, on 21 and 8 august 2005 from MODIS-Level 1, In order to make spatial TPW maps of ...
متن کاملCombined use of MODIS, AVHRR and radiosonde data for the estimation of spatiotemporal distribution of precipitable water
[1] In this paper, the atmospheric precipitable water (PW) was estimated by means of Advanced Very High Resolution Radiometer (AVHRR) thermal channels brightness temperature difference (DT), over the broader area of Greece. The AVHRR derived DT was calculated in a grid of 5 5 km cells; the corresponding PW value in each grid cell was extracted from Moderate Resolution Imaging Spectroradiometer ...
