Huatajata weather station - Coastal monitoring
Prepared by Xavier Lazzaro (IRD/BOREA)
& Javier Maldonado Alfaro (IIGEO/UMSA)
Location, characteristics, and purpose
We wanted to compare the meteorological conditions at the water surface of Lago Menor with those on land. For this, we use the time series of the IRD Campbell weather station (owned by BOREA/IRD), including a rain gauge (Fig. 1-left), deployed in 2012 on the shore of Huatajata (lat. -16.213242º S, long. -68.690342º W), on the property of the Catari family. It is located 4 km from the buoy, in a straight line. This question is crucial, since: a) All SENAMHI weather stations are located on land in the lake basin. b) Data from these stations are used to calculate the water balance of the lake. c) If conditions at the water surface differ, could they alter the calculation of the balance? And d) The HydroMet buoy is the first meteorological station deployed over Lake Titicaca available for this purpose.
Figure 1 - Left: IRD Campbell weather station installed in 2012, on the shore line of Huatajata, 4 km from the HydroMet Buoy. Equipment: Campbell CR1000 datalogger, solar panel, anemometer, hygrometer, LiCOR quantameter, spectrophotometer and mechanical rain gauge. The data adquisition frequency is set to 15 min. Right: Map of the Huatajata coastline with the location of the Campbell weather station (in yellow) on the property of the Catari family, behind the Titi Museum of ancient navigation (i.e. aboard totora reed rafts) and the gas station.
