INHALE

INHALE is supported by the ANR Agence Nationale de la Recherche (ANR-15-CE01-0002-01)
It seeks to characterize for the first time atmospheric microbial life on a global scale as linked with biogeochemical cycles

Amsterdam Island is a 10km wide rock situated in the southern Indian Ocean, 3400km and 5000km downwind from the nearest lands, Madagascar and South Africa, respectively.
The Hi-vol sampler was installed at the Pointe Bénédicte station, at the northwest end of the island, 55m above sea level and 2km west of the scientific base (30 residents at most).
The 2 month campaign took place from September to October 2016 thanks to the collaboration of the French Polar Institute IPEV program (...)

From October to December 2016, we sampled aerosols at the Cape Point Global Atmosphere Watch (GAW) station (34° 21′S, 18° 29′E) which is managed by the South African Weather Service (SAWS). The laboratory is located about 60 km to the south of the greater Cape Town area. It is situated within a National Park at the southern tip of the Cape Peninsula on top of a cliff (230 m a.s.l.). The station has been in operation since 1978 and its current continuous measuring program includes Hg (GEM), CO, (...)

We have started our sampling campaign at the summit of the Chacaltaya (5320m asl) and hope to continue until next fall 2016. Chacaltaya is located in the Bolivian Andes (16°21’S, 68º07’W) close to La Paz (google map).
For this experiment, we have a strong partnership with Universitad Mayor de San Andres of La Paz (UMSA) and Marcos Andrade’s group at the LFA. This action is also coordinated with the Chacaltaya GAW observatory and with the help of the Institut de Recherche et Développement (...)

Three samples were collected at the French-Italian station Concordia (75◦06 S, 123◦20 E, 3220m above sea level) during the summer (December-January). The station is located on the Antarctic plateau, 1100km away from the nearest coast of East Antarctica.
The air temperature ranges between −20 ◦C in summer and−70 ◦C in winter, with an annual mean value of −45 ◦C. There is permanent daylight in summer and permanent darkness in winter. Snow accumulation is ∼10cm/ (...)

Nam Co site is situated on the Tibetan Plateau and run by the Institute of Tibetan Plateau Research of the Chinese Academy of Science.
The station (30°46’N, 90°59’E, 4730 m a.s.l), located in the southeast shore of the Nam Co, northern slope of the Nyainqentanglha Mts, was established by the Institute of Tibetan Plateau Research, CAS in 2005. Research in the station focuses on multisphere interactions in the geo-system.
Sampling began in May 2017 thanks to a very fruitful collaboration with Dr (...)

Thanks to our collaboration with Nicolas Marusczak and Jeroen Sonke (GET Toulouse), we have begun sampling at the Pic du Midi. The Pic du Midi is located in the South of France in the Pyrénées moutains (here) at an altitude of 2876 m. Our sampling system is housed at the Observatoire Midi-Pyrénées, a huge facility dedicated to Earth and astronomic observations.
This part of the program is linked to Microdust (IDEX (...)

1 year of intensive sampling of atmospheric microbes has recently started at the Puy de Dôme station (PUY, 45 46N, 2 57E, 1465 m asl.). PUY is a GAW station operated by CNRS and University Blaise Pascal Clermont Ferrand within the framework of the national atmospheric chemistry network. PDD is located a few tens of km from local sources of pollution and the air is representative of the synoptic-scale atmospheric composition of the regional atmospheric background.
This experiment is (...)

Storm Peak Laboratory (SPL) is a high altitude experimental facility situated in the Rocky Mountains of northwestern Colorado (3220 m M.S.L. ; 40.455 deg N, -106.744 deg W). We took samples from July to september 2017 thanks to the help of Gannet Hallar and Ian McCubbin.
The Hi-vol sampler was kindly provided by James Schauer and Christopher Worley at University of Wisconsin-Madison and we also thank Ross Edwards at Curtin (...)

Villum Research Station is a research facility at the military outpost Station Nord in high arctic North Greenland (81°36’ N, 16°40’ W).
Sampling campaign has started early march 2017 after the polar sunrise. This project is made possible thanks to the collaboration with Professor Henrik Skov at the Department of Environmental Science at Aarhus University in Denmark. We also thank Bjarne Jensen and field worker (Benny and (...)
