Station Network Description Pilot Balloon Data

We are processing the data. We will be adding information to this page as soon as it gets processed. Sorry for the delay.

Station Network Description.

The Salar de Uyuni Field Experiment station network was formed by 5 main sites which served as pilot balloon operation centers. Four of these sites were located near the edge of the salar, whereas a central site was located close to Incahuasi Island.

Measurements taken include hourly pilot balloon launches, higher frequency (15 minutes) 3-level temperature observations, 15-minute surface wind estimation and sky observations. The central site also took some radiation measurements as well as surface temperature measurements. Hourly rainfall and cloud photography were also performed. The temperature observation levels were 2cm, 1.5 m and 4 m.

The network was enhanced by the installation of maximum and minimum temperature thermometers at different points of the salar.

Pilot Balloon Data.

So far corrected pilot balloon sounding data are available. This information can be found in ASCII format. The archives have "COR" and "WIN" extensions, and they have been produced by the program "CORRIGE". The ascent rates considered were of 3.2 m/s for 30 gram balloons and 1.6 m/s for party balloons. However, you must take into account that the data located on this page is still being exposed to quality control, therefore we suggest to use this data just for simple qualitative analyses, but not for a deep research topic yet. We will inform you as soon as the data is totally reliable.

We have prepared a data availability table, which shows which data has been collected. To enter click here.

The following archive contains all the pilot balloon information gathered on the experiment. It is a tarred and zipped file. It has around 1 MB, therefore it can fit on a floppy disk. Again, be aware that the data is not totally reliable.
