Abstract:
New approach for calculating the spatial field of prospective pollution sources for remote territories has been suggested. It is based on the analysis of long-term data on air masses transport, been taken from the reanalysis data of NOAA (www.arl.noaa.gov/ready). 5-day backward air mass trajectories have been calculated to the point inside the area of Nenetzky Nature Reserve (the Pechora River delta) for each day of January and July during 10 years (2001–2010). These two months have the most contrasting climatic characteristics in a year. The results on atmospheric heavy metals concentrations at the Reserve territory showed good agreement with other estimates and experimental data for the nearest sites. The maps presented give visual information on average spatial distribution (for every month) of prospective pollution sources for the Reserve environment. Such fields for distant and protected territories can be used for comparing contributions from different existing sources and anthropogenic sources being in project, as well as from extensive sources such as fires of different origin.
