GuMNet: Guadarrama Monitoring Network

Technical data

Technical description of the equipment

The GuMNet (Guadarrama Monitoring Network) infrastructure consists on 10 real time automatic weather stations installed in the Sierra de Guadarrama with instrumentation for monitoring the state of the atmosphere, surface and the subsurface. The atmosphere monitoring conditions satisfy the standards of the World Meteorological Organization (WMO) concerning variables such as air temperature and relative humidity, wind speed and direction, precipitation, radiation and thickness of the snow cover. GuMNet is an infraestructure proyect installed on the basis of the meteorological network of the former Natural Park Peñalara, proclaimed Sierra de Guadarrama National Park (PNSG) by Law 7/2013 of 25 June 2013.

Complementing the atmospheric measurements, subsurface infrastructure is incorporated into the network with a total of 15 boreholes of up to 20 meters deep and 9 trenches of up to 1 meter depth. In the boreholes the temperature is monitored at 8 detphs sensors placed at different depths. In the trenches they are directly inserted temperature and humidity sensors at different depths. Furthermore our team of soil scientists has characterized soil types and composition of the horizons performing a test pit at each station to provide a valuable description of the environment as metadata, enabling a better interpretation of the data observations collected by the automatic stations.

Involved equipment

  • 10 real time automatic weather stations installed in the Sierra de Guadarrama connected via GPRS.
  • Collection of soil samples taken at 5 cm depth intervals in each of the 9 trial pits practiced in 8 sites.
  • Collection of core rocks extracted along 15 boreholes carried out in most GuMNet stations.
  • Set of measuring sensors and instrumentation to monitor the state of the atmosphere.
  • Set of sensors and measuring device to monitor surface and subsurface thermodynamic evolution.
  • Human science team coordinated through various working groups.
  • GPRS connection system between each station with the central storage server through the management software for storing observations and network control.
Action data

Need and description of the action

The GuMNet (Guadarrama Monitoring Network) project was born within the Campus of International Excellence (CEI): Moncloa Campus as a collaboration between the Complutense University of Madrid, the Polytechnic University of Madrid, the CIEMAT (Centre for Energy, Environmental and Technological Research) AEMET (State Meteorological Agency) and the National Park of the Sierra de Guadarrama (PNSG).

The GuMNet infrastructure project consists in implementing an hydrometeorology observational network in the Sierra de Guadarrama, just 50 Km northwest of the city of Madrid. GuMNet lays the fundations of a network for research and climate, weather and environment in the Sierra de Guadarrama observation. This project represents a first step to provide a unique framework in an environment of high protection to be use as an observatory serving a wide range of scientific research.

The database generated by GuMNet will attract future studies concerning environmental and climate change in the context of ecosystems in middle and high mountain areas. This valuable source of data will generate a space for scientific collaboration with other national and international institutions. The diversity of potential uses of the network GuMNet will be very useful in education at all levels; from basic cycles, higher degrees and research.

Conceptually, GuMNet intend to use such a well known space such as the Sierra de Guadarrama in a laboratory for interdisciplinary research. On one hand, a space for exchange of observations and scientific discursión among researchers is generated. On the other hand, online platforms and various informative materials will allow the public to acces the results from different research lines developed around this region.


1. Provide to the newly opened Sierra de Guadarrama National Park an infrastructure of the highest quality for monitoring the state of the atmosphere and subsurface.
2. Use a space of maximum environmental protection as a laboratory to develop educational and research activities based on a comprehensive database as a matter of excellence for its extensive coverage and quality controls.
3. Generate a center of attraction of experimental science in high mountain environments in the International Campus of Moncloa. With projection for a broad spectrum of disciplines, in order to generate synergies between different groups of national and international research.
4. Install an infrastructure with a remote connection from the Campus quasi-online that allow experimentation with new sensors and instrumentation device.
5. Practical use of a software tool to manage and control network based on open source technology to enable future extensions, revisions in the sense of R+D from disciplines related to telematics, computer and radio control.
6. Use a web portal for generating products of scientific activity designed to popularize sciencie and technology for the general public. In order to improve communication between research activities and the needs and concerns of the general public.

International aspects

GuMNet consortium integrates institutions with in the Interational Campus of Excelence Moncloa: Complutense University of Madrid (UCM), Politecnic University of Madrid (UPM) and the Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (CIEMAT) joined with institutions outside the Campus: (PNSG and AEMET).
The consortium has already had contact with other international observational networks for future collaboration.
