Determination of Water Vapour on Boga Station using Observable GPS

This work shows the goodness that GPS technology offers the possibility of estimating the amount of precipitable water vapor in the atmosphere permanently and continuously because it does not have climatological limitations as well as its low cost, which contrasts with the conventional meteorological techniques such as the radio sounding, the radiometer and the photometers, which present limitations regarding temporality and spatiality in the data taking, likewise each country has a National Geodesic Network that if it is well densified, in this type of studies it offers a greater spatial resolution. The distribution of water vapor in the atmosphere varies about latitude so that studies have determined that at higher altitudes, water vapor decreases, from this it is derived that in the poles the water vapor is 10 times smaller than in latitudes near the terrestrial equator, the water vapor also varies about the altitude, so that this decreases quickly as the altitude increases, thus concentrating in the layer of the atmosphere
