What services do we offer?
Research & Development
interMET personnel have participated activelly in numerous research and development projects along with other companies and research groups. We trully believe in knowledge economy and we think that we have many things we could do to enhance your research project. If your are looking for outsourcing certain areas of your project and concentrate on others, do not doubt to contact us.
Mostly of the systems, methodologies and professional capabilities we can now offer to you are a consecuence of internal research and development. Here we show some of the R+D lines that we are currently working on and some related peer review publications and presentations:

For ome of them we are looking for financiation while others progress some how with self-financiation. Maybe some of them sound interesting for you and would like to participate. In that case do not doubt to contact us so we can look for sinergies.
Do you have a research project?
With the first station taking first measurements on 1998 at 2080 m height, this network was during a long time a pioneer in alpine automatic measurments. This project has been for interMET not just a project, it has been our workbench that made our human and technical skills to be taken almost to the limit.
Based on our experience in monitoring in alpine climates we were asked to design, install and maintain "the best" hydro-meteorological network that could be imagined in a mountain area. Considering how difficult it is to achieve reliable measurements in this environments we have proposed and installed a network base on gravimetric rain gauges, snow height sensors, 4 components radiation and specially designed sensors and systems for this environments.
Met masts with mechanical anemometers and wind vanes have being the standard for wind power assessment during many years. This measuring principle relies on the conversion of the wind energy into mechanical energy that anemometers and wind vanes convert to an electric signal proportional to wind speed or wind direction. Like any other measuring technique, anemometers and wind vanes have their advantages and disadvantages. One of the limitations of anemometers and wind vanes is that that they need a solid structure to be held at a certain height, the other is that they take samples of wind almost in a single point. In the last decades, size of wind turbines have grown considerably. With this increment on rotor height, a more precise assessment of the wind profile is then necessary in order to make a better production forecasting. It is possible to use tall towers with sensors all their way up to 100 meters or more, but the increase of the costs of such towers increase considerably. This fact along with others like reliability, installation and maintenance costs and environmental impact make necessary to consider other measurement techniques that do not need towers. One option is to use a SODAR (SOund Detection And Ranging). They use the heterogeneities found on air to reflect ultrasonic sound pulses and retrieve their velocity using the Doppler effect theory. SODARs are at ground level but can reach very high levels of the atmosphere, depending on their configuration. SODARs specially focused on the first hundreds of meters of the atmosphere have become in the last years very helpful on the wind energy resource area.
The objective of this project was to have a rugged, compact housing for scientific quality meteorological sensors, data logging and telecommunication equipment. This housing should be easy to install and make minimum impact on the environment: no fences, no civil work and low visual impact.
Laser based disdrometers seem complex equipment but are fantastic for measuring precipitation characteristics like size and velocity of water drops or snow flakes. Our client wanted to monitor precipitation very intensively in a small area and we were asked to install more than a dozen of these in an are of less than 8 km square! No problem on replicating the same system for several locations, but they wanted size and velocity of precipitation every minute!. Here the challenge was data logging and reporting taking into account the huge amount of data sampled. It was solved designing an ad-hoc logger that showed an excellent performance even being solar powered.
We had imagined we would have to build a wind tunnel since we have been in the wind power sector, but never thought we would have to build a fireproof wind tunnel! One good thing was working indoors. We had to think hard to solve this client's needs. They wanted to reproduce and measure wild fires in a laboratory reproducing nature. It keeps working!
