Measurement Sites

 

Network RAMCES consists of observatories (in-situ measurements), of flask sampling measurements in fixed surface sites, on-board small aircraft and on-board ships.

In-situ measurements

Observatories

Measurements began in 1980 at the Amsterdam Island observatory , in 1992 at Mace Head, since 2000 at Puy de Dôme and in Saclay with the LSCE. Three sites make it possible to study different environments: influence of marine currents at Mace Head, activities rural at Puy de Dôme and urban activities with Saclay.

Mace Head Observatory in Irlande

Puy de Dôme Observatory in Auvergn

Saclay Observatory near Paris

Weekly/monthly measurements

 

Air Samples are taken in pyrex bottles of 2l according to a protocol developed with the LSCE, with cooperation of CMDL/NOAA. Flasks are sampled at weekly or monthly frequency in fixed surface sites, on-board small aircrafts and during oceanographical campaigns. Approximately 2000 measurements per annum are taken.
