Dataset Title |
YAK-AEROSIB Project: Regional airborne observations of the atmospheric chemical composition in Eurasia |
|
Dataset Purpose |
The Airborne Extensive Regional Observations in Siberia (YAK-AEROSIB) French-Russian project aims to fill the existent gap of large scale observations of the chemical composition of the Siberian air shed, Systematic observations of atmospheric concentrations in CO2, CH4, CO, O3 and aerosols over the interior of Eurasia

Dataset Abstract |
New aircraft high-precision measurements of the vertical distribution of CO2, CH4, CO, O3 and aerosol are performed in the Siberian troposphere on transects of more than 8000 km, and also new and existing datasets are analyzed. This projects builds upon the successful YAK-AEROSIB GDRE project (2003-2010). |
|
Acquisition Methodology |
Each campaign consists typically of 4 flights sampling the same transect of the troposphere, connecting Novosibirsk and Yakutsk and back. A series of around 26 vertical profiles are collected during each campaign. Each profile takes about 30 minutes, including horizontal plateaus at 0.5 and 7 km, and at 5 km on descents. The flights are performed in all-weather conditions, and flight pattern may be altered to avoid large clouds. The times of flights were dependent on logistical constraints. Diurnal variations of the BL height are expected to affect the comparability of individual profiles, but these differences tend to compensate over a whole flight, when making composite profiles.

Quality |
The quality of the measurements is linked to each individual campaign. |

Use Constraints |
Please consider the following fair-use data policy as cited in the project website:
1. Inform us, early in the research, about the expected use of the data.
2. If the research is going to be published, consider offering co-authorship to relevant PI of the project when appropriate.
3. If the research is going to be published, please cite the overview paper (Paris et al., B. Am. Meteorol. Soc., 91 (5), 625-641, 2010) and acknowledge the data source, e.g. ââ¬Ådata obtained from the LIA YAK-AEROSIB with support from CNRS, CEA and ANR in France and RFBR and RAS in Russiaââ¬Â
4. Do not distribute the data to other groups. We will be happy to provide them with the data without delay. |
