Site geographical details
High tower

Overview of the site

The Trainou tall tower (TRN) is located in France at 100km South of Paris and 20km North/West of Orleans. It is surrounded by the Orléans Forest and small cities. The 200m height tower is owned by the French telecommunication company TDF. It has been equipped in 2006 with air inlet at three elevations: 50m, 100m and 180m above the ground, and with meteorological sensors at 180m and 10m. LSCE (Laboratoire des Sciences du Climat et de l'Environnement) has installed one shelter to host several continuous analysers and one flask sampling unit. Currently there is one gas chromatograph analyzing CH4, N2O, SF6, CO, and one non-dispersive infrared analyzer for CO2. Another GC will be setup in 2008 to measure H2 and CO, and Radon measurements will be installed at the 100m level. A small aircraft is flying over the tower, up to 3000m agl, once a week for CO2 in-situ measurements and flask sampling. Internet access is available and the instruments can be remotely controlled from LSCE at Gif sur Yvette. One technician is performing routine operations once a week.
