ZWD

Former ISO 4217 code for the Zimbabwean dollar. It replaced the Rhodesian dollar following (official) independence from Britain in 1980 and was used until hyperinflation forced a change to a new currency code in 2009. It was used for the first, second, and third Zimbabwe dollars. See also: ZWL.

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 [8].
SWD([epsilon],[theta]) = m([epsilon])*(ZWD + cotg [epsilon] ([G.sub.N]*cos[theta] + +[G.sub.E]*sin[theta]) + R,
