This research dedicated to the investigation of the principles and techniques that could be applicable for studying of the climate change that take part at the northern regions of Russia. The research aim is the elaboration of approach and tools for detailed climate monitoring at the territories, which are poorly covered with the ground meteorological observation network.
Due to this aim, the dependences between the XXI century climate change and condition of the non-forest land cover (i.e. shrubs, grasslands, floodplains) were investigated. Taking into account the high vegetative dynamics of these areas, we could use them as a climate indicator of the taiga zone. The 16-day averaged Normalized Differential Vegetation Index (NDVI) was used as the characteristic of land cover state. The standard NDVI product was used, which derived from Terra/MODIS space imagery (spatial resolution of 250 m/pix). The air temperature and precipitation were used as the direct climate change indicators, which were collected on meteorological stations at the study region. The temperature trends, precipitation trends and NDVI trends were calculated. These trends were used for estimation of the dependences between the NDVI magnitude and the values of meteorological parameters.
The comparison of the linear trends shows the high conformity between the dynamics of the meteorological parameters and NDVI of the non-forest land cover. The trends confirmed the hypothesis on that the monitoring of the non-forest land cover conditions and dynamics could be used for studying of the climate change.
The study was partially supported by Russian Foundation for Basic Research (RFBR), research project No. 14-05-00858 A.
