They concluded that the mean difference of ZWD
was 0.8 mm (radiosonde showing higher values).
Slant path wet delay observations are retrieved for the ZWD GAMIT determination, using the mapping function formulation (Boehm et al., 2006) implemented in our software.
The ZWD mean profiles are introduced also in the tomographic equation system as external information with a discretization on the A matrix assuming the same negative exponential decay with altitude used for the characterization of the exiting rays that cross the grid lateral boundaries.
Al respecto, el ZWD
se estimo a partir de las observaciones GPS y del modelo Wet-Niell (Niell, 1996), calculando los parametros troposfericos especificos del lugar de observacion con una resolucion temporal de 30min.
Accordingly, the percentage change in the price level in Zimbabwe equals the percentage change in the exchange rate (ZWD
per unit of USD).
The resulting Zenith Total Delay (ZTD) by processing GNSS data, which is caused by the tropospheric refraction, is divided into two components: 1) the hydrostatic part called Zenith Hydrostatic Delay (ZHD) and 2) the non-hydrostatic delay part called Zenith Wet Delay (ZWD
) (Davis et al., 1985) or Wet Tropospheric Delay (WTD).
GNSS-derived PWV is obtained from the ZWD
multiplying by a conversion factor n [21, 22] which is a function of weighted-mean temperature ([T.sub.m]) over the station .
SWD([epsilon],[theta]) = m([epsilon])*(ZWD
+ cotg [epsilon] ([G.sub.N]*cos[theta] + +[G.sub.E]*sin[theta]) + R,
The ZTD can be split into hydrostatic ZHD and wet ZWD
component of the delay:
