Importance of grasslands monitoring applying optical and radar satellite data in perspective of changing climate

Grasslands deliver wide range of ecosystem services such as carbon sequestration, water quality, flood and erosion control as well as biomass. But since they are impacted by climate change, there is a need for their constant monitoring. Due to climate changes the following grasslands growth conditions are modified: soil moisture, biomass and as a consequence carbon balance. Required multi-temporal and spatial observations are possible with satellite data. The objective of this paper is to present the long term observations of temperature and vegetation conditions (NDVI) of grasslands on the basis of MODIS satellite data as well as already performed and further scheduled frequent analysis of carbon balance, soil moisture and biomass performed with the application of Sentinel1 A; B and Sentinel2 A&B.
